The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

The embodiment of the present application provides a control device for a bi-color lamp. FIG. 1 is a schematic structural diagram of a control device for a two-color lamp in an embodiment of the present application. Referring to FIG. 1 , the control device for a two-color lamp may include: a control device 101 and a two-pin dual-color lamp 102 connected to the control device 101 . ;in,

The dual-pin dual-color lamp 102 includes: a first LED 1021 and a second LED 1022, the first LED 1021 can display the first color when it is lit, and the second LED 1022 can display the first color when it is lit. Two colors, and the first LED 1021 and the second LED 1022 cannot be lit at the same time;

The control device 101 is used 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; based on at least the first frequency division signal and the second frequency division signal signal and fundamental frequency signal to generate a control signal; send the control signal to the two-pin two-color lamp 102, and control the two-pin two-color lamp 102 to alternately display the first color and the second color at a preset flickering frequency to achieve mixed output. A third color, wherein the third color is different from both the first color and the second color.

Here, the above-mentioned clock signal may be a signal generated from an external signal source, such as a crystal oscillator.

Here, the above-mentioned control signal is used to control the two-pin two-color lamp to alternately display the first color and the second color at a preset flickering frequency. The above-mentioned control signal is a signal with a preset flickering frequency.

In practical applications, still referring to FIG. 1 , the two-pin two-color lamp 102 may include: a first pin and a second pin, then, two GPIOs (General Purpose Input/Output) of the control device 101 need to be used , general-purpose input/output) pins, can realize the connection between 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 with the two-pin two-color lamp 102 The second GPIO pin of the control device is connected to the second pin of the dual-pin dual-color lamp 102 .

In practical applications, when the control device controls the LED in the dual-pin dual-color lamp to light up, if the control device controls the first GPIO pin to output a high-level electrical signal, and controls the second GPIO pin to output a high-level electrical signal at the same time A low-level electrical signal can light up the first LED, so that the two-pin two-color lamp displays the first color, and if the control device controls the first GPIO pin to output a low-level electrical signal, and controls the second GPIO pin to output a low-level electrical signal The GPIO pin outputs a high-level electrical signal at the same time, so that the second LED can be turned on, so that the two-pin two-color light can display the second color. Then, in order to light up the first LED and the second LED in a mixed light manner, the first GPIO pin can output a high-level electrical signal at a suitable preset frequency, and the second GPIO pin can output a high-level electrical signal at the same time. Low-level electrical signal, and let the first GPIO pin output a low-level electrical signal, and the second GPIO pin output a high-level electrical signal at the same time, so that the first LED and the second LED will be based on presets. The frequency of the two-pin two-color lights will alternately display the first color and the second color, so that the mixed light effect can be achieved, that is, based on the visual persistence phenomenon, the user can see the first color and the second color. The third color produced after mixing.

Then, in a specific implementation process, the above-mentioned control signal may include: a first GPIO signal and a second GPIO signal conforming to the preset flickering frequency, wherein the levels of the first GIPO signal and the second GPIO signal are different.

Further, the above control device can be specifically used 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 The two-pin two-color lamp alternately displays the first color and the second color at a preset flickering frequency, so as to realize the mixing of a third color different from the first color and the second color according to the visual persistence phenomenon. In this way, by using only two GPIO pins of the control device, the dual-pin dual-color lamp can generate more than two colors, which can improve the control effect of the dual-pin dual-color lamp. Therefore, when the control device of the two-color lamp is applied to practical applications, it can be realized by controlling the two-pin two-color lamp to display different colors to indicate different information to the user, and the different colors can make it easier for the user to display different colors. By distinguishing the differences, users can make more efficient judgments, and the application effect of the two-pin two-color lamp can be improved.

At this time, an 8-bit temporary register can usually be used to store the 6-bit information.

For further example, if the control device is a BMC, the register can be set by the BMC through the I2C (Inter-Integrated Circuit) bus; if the control device is a PCH, the register can be set by the PCH through the LPC (Low Pin Count, low pin count) bus or eSPI (Serial Peripheral Interface, serial peripheral interface) bus to set. In practical applications, the specific implementation manner depends on actual hardware conditions and user requirements, and can be set by those skilled in the art according to actual application conditions, which are not specifically limited in the embodiments of the present application.

In this way, by controlling the control device based on the control signal generated by the frequency-divided clock signal, the two-pin two-color lamp is controlled to display the first color and the second color alternately at the preset flickering frequency. According to the visual persistence phenomenon, it is possible to realize Controlling the two-pin two-color lamp to produce a mixed light effect, that is, generating a third color that is different from the first color and the second color, thereby enriching the control effect of the two-pin two-color lamp and improving the two-pin two-color lamp.

In practical applications, since the two LEDs in the two-pin dual-color lamp are different in terms of color and intensity, in order to achieve a better light mixing effect, it is necessary to adjust the two LEDs. The respective lighting weights need to determine the respective action time of the two LEDs. In a pulse cycle, the LED with a longer action time will be brighter, and the LED with a shorter action time will be darker. In this way, by assigning different action times to the two LEDs, different third colors can be mixed based on the first color with different brightness and the second color with different brightness.

In this way, the mode selection information can be stored in the external storage device. Next, when the behavior of the dual-pin dual-color lamp needs to be controlled by the control device, the control device can read the mode selection information from the external storage device, so as to be based on the mode selection information, frequency division signal and arbitration signal to generate the corresponding control signal.

As an example, taking the control device to obtain the mode selection information from the temporary register as an example, 2 bits can be used to represent LED behaviors such as 2Hz blinking, 0.5Hz blinking, constant on and constant off, etc., then, if you want to represent three types of LEDs The behavior of the color can be used in 6bit.
