5. communication protocol (uart protocol)
communication between isdb-t module with external mcu by the uart port or i2c port, the uart protocol detailed as below: (bps=115200)
the mcu controller just need send 3 bytes to the module:
cmd: 0xaa + key code byte + 0x55
byte0 = 0xaa
byte1= key code byte
byte2 = 0x55
mcu receive isdb-t module command
start cmd (0xab) key code byte end cmd (0x55)*
key code byte list below:
key name
value
wake wakewup
0x1b+0x31+0x31(key code byte)+0x7e
应答：0xaa+0xfe+0x55
sleeep
0x1b+0x31+0x32(key code byte)+0x7e
应答：0xaa+0xff+0x55
rec start
0x1b+0x31+0x33(key code byte)+0x7e；不应答
rec stop
0x1b+0x31+0x34(key code byte)+0x7e；不应答
* if any side of both communication started want target confirm response signal,the end cmd should be
equal 0x56 and response 0x55aa signal back.
