| 144 | Basic firmware description. This will remain with |
| 145 | the driver for documentation purposes. |
| 146 | |
| 147 | This represents an I2C firmware file encoded as a |
| 148 | string of unsigned char. Format is as follows: |
| 149 | |
| 150 | char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB |
| 151 | char[1 ]=len0_LSB -> length of first write transaction |
| 152 | char[2 ]=data0 -> first byte to be sent |
| 153 | char[3 ]=data1 |
| 154 | char[4 ]=data2 |
| 155 | char[ ]=... |
| 156 | char[M ]=dataN -> last byte to be sent |
| 157 | char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB |
| 158 | char[M+2]=len1_LSB -> length of second write transaction |
| 159 | char[M+3]=data0 |
| 160 | char[M+4]=data1 |
| 161 | ... |
| 162 | etc. |
| 163 | |
| 164 | The [len] value should be interpreted as follows: |
| 165 | |
| 166 | len= len_MSB _ len_LSB |
| 167 | len=1111_1111_1111_1111 : End of I2C_SEQUENCE |
| 168 | len=0000_0000_0000_0000 : Reset command: Do hardware reset |
| 169 | len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767) |
| 170 | len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms |
| 171 | |
| 172 | For the RESET and WAIT commands, the two following bytes will contain |
| 173 | immediately the length of the following transaction. |
