- Basic firmware description. This will remain with
- the driver for documentation purposes.
-
- This represents an I2C firmware file encoded as a
- string of unsigned char. Format is as follows:
-
- char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB
- char[1 ]=len0_LSB -> length of first write transaction
- char[2 ]=data0 -> first byte to be sent
- char[3 ]=data1
- char[4 ]=data2
- char[ ]=...
- char[M ]=dataN -> last byte to be sent
- char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB
- char[M+2]=len1_LSB -> length of second write transaction
- char[M+3]=data0
- char[M+4]=data1
- ...
- etc.
-
- The [len] value should be interpreted as follows:
-
- len= len_MSB _ len_LSB
- len=1111_1111_1111_1111 : End of I2C_SEQUENCE
- len=0000_0000_0000_0000 : Reset command: Do hardware reset
- len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767)
- len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms
-
- For the RESET and WAIT commands, the two following bytes will contain
- immediately the length of the following transaction.
