| 113 | Basic firmware description. This will remain with |
| 114 | the driver for documentation purposes. |
| 115 | |
| 116 | This represents an I2C firmware file encoded as a |
| 117 | string of unsigned char. Format is as follows: |
| 118 | |
| 119 | char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB |
| 120 | char[1 ]=len0_LSB -> length of first write transaction |
| 121 | char[2 ]=data0 -> first byte to be sent |
| 122 | char[3 ]=data1 |
| 123 | char[4 ]=data2 |
| 124 | char[ ]=... |
| 125 | char[M ]=dataN -> last byte to be sent |
| 126 | char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB |
| 127 | char[M+2]=len1_LSB -> length of second write transaction |
| 128 | char[M+3]=data0 |
| 129 | char[M+4]=data1 |
| 130 | ... |
| 131 | etc. |
| 132 | |
| 133 | The [len] value should be interpreted as follows: |
| 134 | |
| 135 | len= len_MSB _ len_LSB |
| 136 | len=1111_1111_1111_1111 : End of I2C_SEQUENCE |
| 137 | len=0000_0000_0000_0000 : Reset command: Do hardware reset |
| 138 | len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767) |
| 139 | len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms |
| 140 | |
| 141 | For the RESET and WAIT commands, the two following bytes will contain |
| 142 | immediately the length of the following transaction. |
| 143 | |
