Description.
The present invention is mainly by micro controller module (MCU), and (One-Time Programmable ROM, can be primary by OTPROM
Program read-only memory) module, (Multiple-Time Programmable ROM can repeatedly program read-only storage to MTPROM
Device) module, MTP control circuit module can multiple programmable memory control module, infrared module, that is, signal transmitting and receiving module and hard
Part scan module etc. constitutes (as shown in Figure 1).
Micro controller module major function be by processes such as Instruction decoding, deposits, generate corresponding control signal and when
Sequence completes the corresponding function of program institute.
OTPROM module is mainly used for storing the pattern data of program and certain fixations, it is the read-only of support write-once
Memory.
MTPROM module is mainly used for the pattern data that storage learns, it is the read-only memory for supporting repeatedly to be written.
MTP control circuit module mainly include MTP_ADR (address register), MTP_DAT (read-write data register),
Three groups of registers of MTP_CON (control register), are respectively used to the value of the address of storage MTP, MTP write-in or reading, and
The control signal of MTP.The value that this three groups of registers are controlled by MCU can be completed to MTPROM writing, reading or erasing
Etc. processes.
Infrared module is mainly used for the transmitting of remote signal and receives decoding process.
Hardware scanning module is mainly used for cooperating the wake-up of the complete paired systems of software and determines effective key.
The process (as shown in Figure 2) of study:
1, learning state, and the key of specified study are entered by peripheral key；
2, after determining learning key, by the key, corresponding space is wiped in MTP；
3, the extraneous remote signal learnt is received by infrared module decodes, according to " 0 " (low level), " 1 " (high electricity
It is flat), level width and carrier frequency etc. form pattern data；
4, by corresponding program, make MCU to control the write-in that MTP completes related pattern data.
The process (as shown in Figure 3) of signaling:
1, remote controler presses some key, judges which key is pressed by hardware scanning module and software；
2, if it is common key-press, then the corresponding pattern data being stored in OTP are read；If it is study key, then read
Take the corresponding pattern data in MTP；
3, by the pattern data read by the processing of MCU, then launch via infrared module.
In the present invention, the space according to needed for one pattern data of the capacity of MTPROM and storage, by MTPROM points
At 16 sectors, each sector stores the pattern data of a key, therefore can could support up 16 learning-oriented keys.
To the process (as shown in Figure 4) of MTPROM erasing:
It 1, will be in the first address write-in MTP_ADR register for the sector that need to wipe；
2, the erasing position in MTP_CON register is enabled by MCU, MTPROM starts to carry out erase process；
3, after 65ms, the erasing move to designated sector is completed.
To the process (as shown in Figure 5) of MTPROM write-in:
1, the address being written will be needed to write in MTP_ADR register；
2, the data being written will be needed to write in MTP_DAT register；
3, the write-in position in MTP_CON register is enabled by MCU module, MTPROM starts to carry out writing process；
4, after 150 μ s, the write activity to specified address, specified data is completed.
The process (as shown in Figure 6) that MTPROM is read:
1, the address read will be needed to write in MTP_ADR register；
2, the reading position in MTP_CON register is enabled by MCU module, MTPROM starts to carry out readout；
3, after 10 μ s, the reading operation to specified address is completed, the value of reading is saved in MTP_DAT register.
Common study remote controller is learnt using MCU governor circuit and signaling, the code of external eeprom circuit storage study
Type data, due to using two circuits, scheme is at high cost, the present invention built-in MTPROM in MCU governor circuit, outer for substituting
The eeprom circuit connect reduces scheme cost；
Common study remote controller MCU and EEPROM communication at least occupies two I/O ports, and the present invention can reduce occupancy two
I/O port keeps MCU programming more flexible；
Common study remote controller MCU and EEPROM use serial communication, and data throughout is small, MCU and MTP in the present invention
Between parallel communications, data throughout is big.
Built-in MTPROM can be substituted for built-in FlashROM (flash ROM) etc., but the cost meeting of the latter
Height is a bit.
Using built in the invention can multiple programmable memory learning-oriented remote-control circuit structure and learning method, tool
It has the advantages that:
1, it reduces and uses a circuit, and simplify peripheral circuit, so that remote controler overall cost declines；
2, more two common I/O ports under equal conditions, so that supported increased by bond number；
3, internal parallel communications improves the read or write speed of memory, simplifies programming complexity.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
