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. */ struct XC_TV_STANDARD { … };
