Start burning, after 0x0000 is burnt to first chip interior 0x3bfe, sequence number increases to 0x0001；
0x0001 is burnt to second chip interior 0x3bfe by burning again, and sequence number increases to 0x0002；
It circuits sequentially, when Serial No. 0xfffe, burning is completed；
If need to continue burning, in order to avoid 0xffff, sequence number manually re-enters 0x0000.
2, the burning sequence number inside host chip
When host chip (preferably auspicious Sa R7F0C905) burning program, burned 16 bit sequence in the address portion 0xbbfe in the chip
Number.
Programming method is as follows:
Sequence number is manually entered, and after a piece of chip of burning, the increased amount of sequence number is controlled by the value of increment control algorithm.
Citing: starting sequence number inputs 0x0000, and increment control algorithm inputs 0x01, and initial address inputs 0xbbfe.
Start burning, after 0x0000 is burnt to first chip interior 0xbbfe, sequence number increases to 0x0001；
0x0001 is burnt to second chip interior 0xbbfe by burning again, and sequence number increases to 0x0002；
It circuits sequentially, when Serial No. 0xfffe, burning is completed；
If need to continue burning, in order to avoid 0xffff, sequence number manually re-enters 0x0000.
Two, remote controler and host are all made of A7105 radio-frequency module and are communicated (existing normal mode).
A7105 radio-frequency module is configured to receive mode or sending method, and a moment can only use one mode.
Remote controler needs sequence number consistent with host, could normal pairing work.
These are the prior art.
Three, remote controler and host match code process:
1) remote controler communicates the format for sending information to mainboard:
2) format of the host response to remote controler information:
3) match code
Remote controler single-chip microcontroller at the time of initialization, 16 bit sequences of burning is read out from the address chip interior 0x3bfe
Number, and most-significant byte and least-significant byte are splitted into, then remote controler sequence number most-significant byte and remote controler sequence number least-significant byte are stored to remote controler
In the temporary storage of single-chip microcontroller.16 bit sequence number of host is read out from the EEPROM inside single-chip microcontroller (if do not matched before
Code is crossed, then reading is 0xffff), and most-significant byte and least-significant byte are splitted into, then by host sequence most-significant byte and host sequence number low 8
Position storage is into the temporary storage of remote controler single-chip microcontroller.
Host SCM at the time of initialization, 16 bit sequence numbers of burning is read out from the address chip interior 0xbbfe,
And most-significant byte and least-significant byte are splitted into, host SCM then is arrived into low 8 storages of host sequence most-significant byte and remote controler sequence number
Temporary storage in.Read out from the EEPROM inside single-chip microcontroller 16 bit sequence number of remote controler (if not matching code before,
Then reading is 0xffff), and most-significant byte and least-significant byte are splitted into, then by remote controler sequence number most-significant byte and remote controler sequence number least-significant byte
It stores in the temporary storage of host SCM.
4) with before code, remote controler is in transmission state, and mainboard is in reception state.
When needing with code, the command byte curriculum offering in temporary storage is 0x03 by remote controler, is then sent,
After being sent, remote controler enters reception state.
Mainboard receives the information, and the order in information is 0x03, then by high 8 of remote controler sequence number in information and distant
Control device sequence number least-significant byte extracts, and inserts high 8 of the remote controler sequence number and remote controler sequence number of mainboard temporary storage
In least-significant byte.In this way, just containing the sequence number of remote controler and the sequence number of mainboard in mainboard temporary storage.Host will order
Byte content is changed to 0x83, and subsequently into the state of transmission, information is sent.After being sent, host enters reception state.
Wait the confirmation signal that remote controler is sent in 3 seconds.The confirmation signal that remote controler is sent is not received after 3 seconds, then again from EEPROM
In read out before 16 bit sequence number of remote controler (if not matching code before, reading be 0xffff) that stores, and split into high by 8
Position and least-significant byte, are then stored in the temporary storage of host SCM.
Remote controler distribute with code information enter reception state under at most wait 1 second；In 1 second, if receiving the life of host
The information for being 0x83 is enabled, then the sequence number most-significant byte of host and host sequence least-significant byte is extracted, is stored in remote controler
In EEPROM, while inserting host sequence number in remote controler temporary storage high 8 and being gone with host sequence least-significant byte, in this way,
The sequence number of remote controler and the sequence number of mainboard are just contained in remote controler temporary storage, are then returned to transmission state.It is distant
Command byte content is changed to 0x01 by control device, indicates the sequence number for acknowledging receipt of host and stored, and information is sent out
It goes.More than 1 second, then this was abandoned with code.
Host receives the information of remote controler, if command context is 0x01, extracts in remote controler temporary storage
Mainboard sequence number most-significant byte, mainboard sequence number least-significant byte, remote controler sequence number most-significant byte, remote controler sequence number least-significant byte, and and host
The sequence number of same position is matched in temporary storage；If exact matching, then by remote controler sequence number most-significant byte, remote control
Device sequence number least-significant byte is stored into EEPROM.
It is completed with code.
The information received later, host will check remote controler sequence number and host sequence number, and exact matching could handle distant
Control the information of device.
