Embodiment
In order to more clearly describe technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
The present invention is primarily of micro controller module (MCU), OTPROM (One-TimeProgrammableROM, can one-time programming ROM (read-only memory)) module, MTPROM (Multiple-TimeProgrammableROM, can repeatedly program read-only memory) module, MTP control circuit module can repeatedly programmable memory control module, and infrared module and signal transmitting and receiving module and hardware scanning module etc. form (as shown in Figure 1).
Micro controller module major function is by Instruction decoding, the process such as deposits, and produces corresponding control signal and sequential, the function that the program that completes is corresponding.
OTPROM module is mainly used in storage program and some fixing pattern data, and it is the ROM (read-only memory) supporting write-once.
MTPROM module is mainly used in storing the pattern data learning to arrive, and it is the ROM (read-only memory) supporting repeatedly to write.
MTP control circuit module mainly comprises MTP_ADR (address register), MTP_DAT (read and write data register), MTP_CON (control register) three groups of registers, be respectively used to the address of store M TP, MTP write or the value read, and the control signal of MTP.The value being controlled these three groups of registers by MCU can be completed processes such as MTPROM write, reading or erasings.
Infrared module is mainly used in transmitting and the receipt decoding process of remote signal.
Hardware scanning module is mainly used in coordinating software to complete waking up and determining effective button system.
The process (as shown in Figure 2) of study:
1, enter learning state by peripheral button, and specify the button of study;
2, after determining learning key, by space erasing corresponding in MTP for this key;
3, extraneous by the remote signal that learns by infrared module receipt decoding, form pattern data according to " 0 " (low level), " 1 " (high level), level width and carrier frequency etc.;
4, by corresponding program, MCU is made to complete the write of relevant pattern data to control MTP.
The process (as shown in Figure 3) of signaling:
1, certain button pressed by telepilot, judges which button is pressed by hardware scanning module and software;
2 if common key-press, then read the corresponding pattern data be stored in OTP; If study button, then read in the corresponding pattern data in MTP;
3, by the process by MCU of the pattern data read, then launch via infrared module.
In the present invention, according to the capacity of MTPROM and the space that stores needed for pattern data, MTPROM is divided into 16 sectors, the pattern data of each sector storage button, therefore can support at most 16 learning-oriented buttons.
Process (as shown in Figure 4) to MTPROM erasing:
1, will need in the first address write MTP_ADR register of the sector of erasing;
2, by the erasing position in the enable MTP_CON register of MCU, MTPROM starts to carry out erase process;
3, after 65ms, the erasing move to designated sector is completed.
Process (as shown in Figure 5) to MTPROM write:
1, will the address of write be needed to write in MTP_ADR register;
2, will the data of write be needed to write in MTP_DAT register;
3, by the write position in the enable MTP_CON register of MCU module, MTPROM starts to carry out ablation process;
4, after 150 μ s, the write activity to assigned address, specific data is completed.
Process (as shown in Figure 6) to MTPROM reads:
1, will the address read be needed to write in MTP_ADR register;
2, by the reading position in the enable MTP_CON register of MCU module, MTPROM starts to carry out readout;
3, after 10 μ s, complete the reading operation to assigned address, the value of reading is stored in MTP_DAT register.
Common study remote controller adopts the study of MCU governor circuit and signaling, and external eeprom circuit stores the pattern data of study, owing to using two circuit, scheme cost is high, the present invention is built-in MTPROM in MCU governor circuit, for substituting external eeprom circuit, reduces scheme cost;
Common study remote controller MCU with EEPROM communicates and at least takies two I/O ports, and the present invention can reduce and takies two I/O ports, MCU is programmed more flexible;
Common study remote controller MCU and EEPROM adopts serial communication, and data throughout is little, and parallel communications between MCU and MTP in the present invention, data throughout is large.
Built-in MTPROM can replace to built-in FlashROM (flash ROM) etc., but the cost of the latter meeting height a bit.
To have employed in this invention built-in can the repeatedly learning-oriented remote-control circuit structure of programmable memory and learning method, has following beneficial effect:
1, reduce use circuit, and simplify peripheral circuit, telepilot holistic cost is declined;
2, many two common I/O ports under equal conditions, make supportedly to increase by bond number;
3, inner parallel communications improves the read or write speed of storer, simplifies programming complexity.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
