Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The embodiment of the application provides a control device of a bicolor lamp. Fig. 1 is a schematic structural diagram of a control device of a two-color lamp in an embodiment of the present application, and referring to fig. 1, the control device of the two-color lamp may include: a control device 101 and a two-leg two-color lamp 102 connected to the control device 101; wherein,
the dual pin, two color lamp 102 includes: a first LED 1021 and a second LED 1022, the first LED 1021 being capable of displaying a first color when lit, the second LED 1022 being capable of displaying a second color different from the first color when lit, and the first LED 1021 and the second LED 1022 being incapable of being lit at the same time;
a control device 101 for receiving a clock signal from the outside; performing frequency division processing on the clock signal to obtain a first frequency division signal, a second frequency division signal and a base frequency signal; generating a control signal based on at least the first frequency-divided signal, the second frequency-divided signal and the base frequency signal; and sending a control signal to the dual-pin dual-color lamp 102, and controlling the dual-color lamp 102 to alternately display the first color and the second color at a preset flashing frequency so as to realize mixing of a third color, wherein the third color is different from the first color and the second color.
Here, the clock signal may be a signal generated from an external signal source, such as a crystal oscillator.
Here, the control signal is used to control the dual-color lamp of the dual-pin to alternately display the first color and the second color at a preset flashing frequency. The control signal is a signal with a preset flicker frequency.
In practical applications, still referring to FIG. 1, a dual pin, dual color lamp 102 may comprise: the first pin and the second pin, then, two GPIO (General Purpose Input/Output) pins of the control device 101 need to be used to connect the control device 101 and the two-pin two-color lamp 102, so that the first GPIO pin of the control device 101 can be connected to the first pin of the two-pin two-color lamp 102, and the second GPIO pin of the control device can be connected to the second pin of the two-pin two-color lamp 102.
In practical application, in the process that the LED in the double-color lamp of the double-pin is controlled by the control device to light, if the control device controls the first GPIO pin to output a high-level electric signal and controls the second GPIO pin to output a low-level electric signal at the same time, the first LED can be lightened, the double-color lamp of the double-pin displays a first color, and if the control device controls the first GPIO pin to output a low-level electric signal and controls the second GPIO pin to output a high-level electric signal at the same time, the second LED can be lightened, and the double-color lamp of the double-pin displays a second color. Then, in order to realize lighting the first LED and the second LED in a light mixing manner, the first GPIO pin may output a high-level electrical signal and the second GPIO pin may output a low-level electrical signal at the same time at a proper preset frequency, and the first GPIO pin may output a low-level electrical signal and the second GPIO pin may output a high-level electrical signal at the same time, so that the first LED and the second LED may be lighted in turn based on the preset frequency, that is, the dual-color lamps of the dual pins may display the first color and the second color in turn, thereby achieving a light mixing effect, that is, based on a persistence of vision, the user may see a third color generated after the first color and the second color are mixed.
In a specific implementation, the control signal may include: and the first GPIO signal and the second GPIO signal accord with the preset flicker frequency, wherein the first GIPO signal and the second GPIO signal have different levels.
Further, the control device may be specifically configured to send the first GPIO signal to the first pin through the first GPIO pin and send the second GPIO signal to the second pin through the second GPIO pin, so that the dual-color lamp with the dual pins alternately displays the first color and the second color at a preset flicker frequency, and a third color different from the first color and the second color is mixed according to a persistence of vision phenomenon. Therefore, the double-pin double-color lamp can generate more than two colors by only using the two GPIO pins of the control device, and the control effect of the double-pin double-color lamp can be improved. Therefore, when the control device of the double-color lamp is applied to practical application, different colors can be displayed by controlling the double-color lamp of the double pins to indicate different information to a user, and the user can distinguish the difference easily due to the different colors, so that the user can achieve more efficient judgment, and the application effect of the double-color lamp of the double pins can be improved.
For example, if the control device of the two-color lamp is applied to the field of a debugging lamp, a power button, and other server fields, it is possible to indicate different types of information with different colors, for example, in the field of the debugging lamp, a native first color may represent a power abnormality, a light-mixed third color may represent a power-on/power-off state, and a native second color may represent a Port 80 of a PCH (Platform path Controller ); in the field of power keys, a native first color may represent that a server power is turned on/off, a third color of mixed light represents that a power is abnormal, and a native second color represents that a BMC (Baseboard Management Controller) is abnormal. Therefore, the user can more intuitively and clearly know what kind of information the two-color lamp is currently representing.
In practical applications, the control Device may be implemented by an IC (Integrated Circuit) chip having a control function, such as a BMC (baseboard management controller), a CPLD (Complex Programmable logic Device), an MCU (micro control Unit), an FPGA (Field Programmable Gate Array), a PCH (Integrated Circuit), and the like. Of course, other implementations are possible, and the embodiments of the present application are not limited in detail herein.
In practical applications, because two LEDs in a dual-pin dual-color lamp have differences in color, intensity, and the like, in order to achieve a better light mixing effect, the respective lighting weights of the two LEDs need to be adjusted, that is, the respective action times of the two LEDs need to be determined, and in one pulse period, an LED with a longer action time is brighter, and an LED with a shorter action time is darker. Thus, by assigning different operation times to the two LEDs, a different third color can be mixed based on the first color of different brightness and the second color of different brightness.
In other embodiments of the present application, in order to achieve a better light mixing effect, the above control device may be further specifically configured to: generating a first arbitration signal for controlling the action time of a first LED in the dual-pin dual-color lamp and a second arbitration signal for controlling the action time of a second LED in the dual-pin dual-color lamp based on the fundamental frequency signal; acquiring mode selection information for indicating a preset flicker frequency; the control signal is generated based on the mode selection information, the first frequency divided signal, the second frequency divided signal, the first arbitration signal, and the second arbitration signal.
In practical applications, the mode selection information may be used to indicate the action mode of each LED, for example, one or more combinations of behaviors of constant on, constant off, flashing at 2Hz, flashing at 0.5Hz, and the like. The mode selection information may be set by a person skilled in the art according to actual needs, and the embodiments of the present application are not limited in detail herein.
In practical applications, the control device may be connected to an external storage device, such as a register, etc., and the mode selection information may be preset by the control device according to the requirements of practical applications. Thus, it is possible to realize the mode selection information stored in the external storage device. Next, when the behavior of the dual-pin two-color lamp needs to be controlled by the control device, the control device may read the mode selection information from the external memory device to generate a corresponding control signal based on the mode selection information, the frequency division signal, and the arbitration signal.
As an example, taking the control device to obtain the mode selection information from the temporary storage as an example, 2 bits (bits) can be used to represent the behaviors of the LED such as 2Hz blinking, 0.5Hz blinking, constant on and constant off, and 6 bits can be used if the behaviors of three colors are to be represented. In this case, an 8-bit temporary storage can be used to store the 6-bit information.
Further for example, if the control device is a BMC, the register may be set by the BMC through an I2C (Inter-Integrated Circuit) bus; if the control device is a PCH, the register can be set by the PCH through an LPC (Low Pin Count) bus or an eSPI (Serial Peripheral Interface) bus. The specific implementation manner in the practical application depends on the actual hardware condition and the user requirement, and can be set by a person skilled in the art according to the practical application situation, and the embodiment of the present application is not specifically limited herein.
In a specific implementation process, in order to generate a control signal for controlling a dual-color lamp with dual pins to alternately display a first color and a second color at a preset flashing frequency, the control device may further specifically be configured to: generating a driving signal according with a preset flicker frequency based on the mode selection information, the first frequency-dividing signal and the second frequency-dividing signal; the control signal is generated based on the drive signal, the first arbitration signal, and the second arbitration signal.
In practical applications, the frequency of the first frequency-dividing signal is related to the frequency of the flashing behavior of one LED, and the frequency of the second frequency-dividing signal is related to the frequency of the flashing behavior of another LED.
In a specific implementation process, in order to generate an arbitration signal for controlling the actuation time of the first LED and the second LED, the control device may further include: counting based on the fundamental frequency signal to obtain a count value; allocating the action time of the first LED and the action time of the second LED according to the count value; a first arbitration signal is generated based on an action time of a first LED, and a second arbitration signal is generated based on an action time of a second LED.
As can be seen from the above, the control device for a dual-color lamp provided in the embodiment of the present application, after receiving a clock signal from the outside, may perform frequency division processing on the clock signal to obtain a first frequency division signal, a second frequency division signal, and a fundamental frequency signal; and then, generating a control signal based on the first frequency-removing signal, the second frequency-removing signal and the fundamental frequency signal, finally, sending the control signal to the double-pin double-color lamp, and controlling the double-pin double-color lamp to alternately display the first color and the second color at a preset flashing frequency so as to realize mixing of a third color, wherein the third color is different from the first color and the second color. Like this, through the control device based on the control signal that clock signal after the frequency cut generated, control the double-colored lamp of double-pin and show first colour and second colour in turn with predetermineeing flicker frequency, according to the persistence of vision phenomenon, just can realize controlling the double-colored lamp of double-pin and produce the effect of mixing light, produce the third colour different with first colour and second colour promptly, thereby, can enrich the control effect of the double-colored lamp of double-pin, improve the application effect of the double-colored lamp of double-pin.
Based on the same inventive concept, the embodiment of the application provides a control method of a bicolor lamp. In practical applications, the control method of the dual-color lamp can be applied to the control device of the dual-color lamp in one or more of the above embodiments, and the control device of the dual-pin dual-color lamp includes: the double-colored lamp of double-barrelled foot includes with the double-colored lamp of double-barrelled foot that controlling means and be connected with controlling means: the LED display device comprises a first LED and a second LED, wherein the first LED can display a first color when being lightened, the second LED can display a second color different from the first color when being lightened, and the first LED and the second LED can not be lightened simultaneously.
Fig. 2 is a schematic flow chart of a control method of a bi-color lamp in an embodiment of the present application, and referring to fig. 2, the control method of the bi-color lamp may include:
s201: the control device receives a clock signal from the outside;
here, the clock signal may be a signal generated from an external signal source, such as a crystal oscillator.
S202: the control device carries out frequency removal processing on the clock signal to obtain a first frequency removal signal, a second frequency removal signal and a base frequency signal;
s203: the control device generates a control signal at least based on the first frequency-dividing signal, the second frequency-dividing signal and the base frequency signal;
here, the control signal is used to control the dual-color lamp of the dual-pin to alternately display the first color and the second color at a preset flashing frequency. The control signal is a signal with a preset flicker frequency.
In practical applications, because two LEDs in a dual-pin dual-color lamp have differences in color, intensity, and the like, in order to achieve a better light mixing effect, the respective lighting weights of the two LEDs need to be adjusted, that is, the respective action times of the two LEDs need to be determined, and in one pulse period, an LED with a longer action time is brighter, and an LED with a shorter action time is darker. Thus, by assigning different operation times to the two LEDs, a different third color can be mixed based on the first color of different brightness and the second color of different brightness.
Then, in order to achieve a better light mixing effect, in other embodiments of the present application, the step S203 may include the following steps 2031 to 2033:
step 2031: the control device generates a first arbitration signal for controlling the action time of a first LED in the dual-pin dual-color lamp and a second arbitration signal for controlling the action time of a second LED in the dual-pin dual-color lamp based on the fundamental frequency signal;
here, the operation time of the first LED and the operation time of the second LED may be the same or different, as required. The method can be set by a person skilled in the art according to the actual application, and the embodiments of the present application are not limited in detail.
Step 2032: the control device acquires mode selection information for indicating a preset flicker frequency;
in practical applications, the mode selection information may be used to indicate the behavior mode of the LED, for example, the mode selection information may be one or more combinations of behaviors of constant on, constant off, flashing at 2Hz, flashing at 0.5Hz, and the like. Then, when the dual-color lamp with the dual pins needs to be controlled by the control device to mix other colors, the control device can acquire the mode selection information for indicating the preset flashing frequency.
In practical applications, the control device may be connected to an external storage device, such as a register, etc., and the mode selection information may be preset by the control device according to the requirements of practical applications. Thus, it is possible to realize the mode selection information stored in the external storage device. Next, when the behavior of the dual-pin two-color lamp needs to be controlled by the control device, the control device may read the mode selection information from the external memory device to generate a corresponding control signal based on the mode selection information, the frequency division signal, and the arbitration signal.
As an example, taking the control device to obtain the mode selection information from the temporary storage as an example, 2 bits can be used to represent the behaviors of the LED such as 2Hz blinking, 0.5Hz blinking, constant on and off, and 6 bits can be used if the behaviors of three colors are to be represented. In this case, an 8-bit temporary storage can be used to store the 6-bit information.
Further for example, if the control device is a BMC, the register may be set by the BMC via the I2C bus; if the control device is a PCH, the register can be set by the PCH through the LPC bus or the eSPI bus. The specific implementation manner in the practical application depends on the actual hardware condition and the user requirement, and can be set by a person skilled in the art according to the practical application situation, and the embodiment of the present application is not specifically limited herein.
Step 2033: the control device generates a control signal based on the mode selection information, the first frequency-divided signal, the second frequency-divided signal, the first arbitration signal, and the second arbitration signal.
As an example, in order to generate the arbitration signal for controlling the action time of the first LED and the second LED, in a specific implementation, the step 2031 may include the following steps 2031a to 2031 c:
step 2031 a: the control device counts based on the fundamental frequency signal to obtain a count value;
step 2031 b: the control device distributes the action time of the first LED and the action time of the second LED according to the count value;
step 2031 c: the control device generates a first arbitration signal based on an action time of the first LED and a second arbitration signal based on an action time of the second LED.
As an example, in order to generate a control signal for controlling a dual-color lamp with dual pins to alternately display a first color and a second color at a preset flashing frequency, in a specific implementation, the step 2033 may include the following steps 2033a to 2033 b:
step 2033 a: the control device generates a driving signal which accords with a preset flicker frequency based on the mode selection information, the first frequency eliminating signal and the second frequency eliminating signal;
in practical applications, the frequency of the first frequency-dividing signal is related to the frequency of the flashing behavior of one LED, and the frequency of the second frequency-dividing signal is related to the frequency of the flashing behavior of another LED.
Step 2033 b: the control device generates a control signal based on the drive signal, the first arbitration signal, and the second arbitration signal.
S204: the control device sends a control signal to the double-pin double-color lamp, and the double-pin double-color lamp is controlled to alternately display the first color and the second color at a preset flashing frequency so as to realize mixing of the third color.
Wherein the third color is different from both the first color and the second color.
Thus, the process of controlling the dual-pin dual-color lamp is completed.
As can be seen from the above, in the control method of the dual-color lamp provided in the embodiment of the present application, after the control device receives the clock signal from the outside, the clock signal may be subjected to frequency division processing to obtain the first frequency division signal, the second frequency division signal, and the fundamental frequency signal; and then, generating a control signal based on the first frequency-removing signal, the second frequency-removing signal and the fundamental frequency signal, finally, sending the control signal to the double-pin double-color lamp, and controlling the double-pin double-color lamp to alternately display the first color and the second color at a preset flashing frequency so as to realize mixing of a third color, wherein the third color is different from the first color and the second color.

In practical application, the double-leg double-color lamp is integrated with the first LED and the second LED, the first LED can display a first color when being lightened, the second LED can display a second color different from the first color when being lightened, and the first LED and the second LED cannot be lightened simultaneously.
In the embodiment of the present application, the arbitration module is specifically configured to allocate an action time of the first LED and an action time of the second LED according to the count value; a first arbitration signal is generated based on an action time of a first LED, and a second arbitration signal is generated based on an action time of a second LED.
For example, for a dual-pin dual-color lamp integrated with a green LED and an amber LED, assuming that the clock signal is a clock signal with a frequency of 25Mhz generated by an external crystal oscillator, then after the frequency-dividing module receives the clock signal with a frequency of 25Mhz from the external crystal oscillator, three signals with frequencies of 2Hz, 0.5Hz, and 1KHz can be obtained, and then the signal with 2Hz can be used as a first frequency-dividing signal to be sent to the LED behavior control module, the signal with 0.5Hz can be used as a second frequency-dividing signal to be sent to the LED behavior control module, and the signal with 1KHz can be used as a fundamental frequency signal to be sent to the counting module, that is, 2Hz and 0.5Hz are frequencies of the LED blinking behavior. Thus, the control signal of the waveform pattern shown in fig. 4 can be generated based on the signals of three frequencies of 2Hz, 0.5Hz and 1KHz, and the control signal is sent to the double-pin double-color lamp, so that the amber LED can be independently lightened, the green LED can be independently lightened, and the amber LED and the green LED can be alternately lightened at a preset flashing frequency.
In practical applications, the frequency dividing module, the counting module, the arbitration module, the LED behavior control module and the LED driving module may be implemented by an IC chip having a control function, such as BMC, CPLD, MCU, FPGA, PCH, etc. Of course, other implementations are possible, and the embodiments of the present application are not limited in detail herein.
As can be seen from the above, an embodiment of the present application provides a control device, including: the LED driving module comprises a frequency eliminating module, a counting module, an arbitration module, an LED behavior control module and an LED driving module, wherein after the frequency eliminating module receives a clock signal from the outside, the frequency eliminating module can eliminate the frequency of the clock signal to obtain a first frequency eliminating signal, a second frequency eliminating signal and a base frequency signal, and sends the first frequency eliminating signal and the second frequency eliminating signal to the LED behavior control module and sends the base frequency signal to the counting module; then, after receiving the fundamental frequency signal sent by the frequency-dividing module, the counting module can count based on the fundamental frequency signal to obtain a count value, and send the count value to the arbitration module; after receiving the count value sent by the counting module, the arbitration module may generate a first arbitration signal for controlling an action time of a first LED in the dual-pin dual-color lamp and a second arbitration signal for controlling an action time of a second LED in the dual-pin dual-color lamp based on the count value, and send the first arbitration signal and the second arbitration signal to the LED driving module; after receiving the first frequency-dividing signal and the second frequency-dividing signal sent by the frequency-dividing module and receiving mode selection information from the outside and used for indicating a preset flicker frequency, the LED behavior control module can generate a driving signal conforming to the preset flicker frequency based on the mode selection information, the first frequency-dividing signal and the second frequency-dividing signal and send the driving signal to the LED driving module; and finally, after receiving the first arbitration signal and the second arbitration signal sent by the arbitration module and the driving signal sent by the LED behavior control module, the LED driving module can generate a control signal based on the driving signal, the first arbitration signal and the second arbitration signal, and send the control signal to the double-color lamp with double pins, and the double-color lamp with double pins is controlled to alternately display the first color and the second color at a preset flicker frequency so as to realize mixing of a third color, wherein the third color is different from the first color and the second color. In this way, the control device is used for scanning and controlling the double-color lamp, and the double-color lamp with the double pins is controlled to alternately display the first color and the second color at the preset flicker frequency. Therefore, according to the phenomenon of visual persistence, the effect of controlling the double-color lamp with double pins to generate mixed light can be realized, namely, a third color different from the first color and the second color is generated, and then the control effect of the double-color lamp with double pins can be enriched, and the application effect of the double-color lamp with double pins is improved.
