148 | Basic firmware description. This will remain with | |
149 | the driver for documentation purposes. | |
150 | ||
151 | This represents an I2C firmware file encoded as a | |
152 | string of unsigned char. Format is as follows: | |
153 | ||
154 | char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB | |
155 | char[1 ]=len0_LSB -> length of first write transaction | |
156 | char[2 ]=data0 -> first byte to be sent | |
157 | char[3 ]=data1 | |
158 | char[4 ]=data2 | |
159 | char[ ]=... | |
160 | char[M ]=dataN -> last byte to be sent | |
161 | char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB | |
162 | char[M+2]=len1_LSB -> length of second write transaction | |
163 | char[M+3]=data0 | |
164 | char[M+4]=data1 | |
165 | ... | |
166 | etc. | |
167 | ||
168 | The [len] value should be interpreted as follows: | |
169 | ||
170 | len= len_MSB _ len_LSB | |
171 | len=1111_1111_1111_1111 : End of I2C_SEQUENCE | |
172 | len=0000_0000_0000_0000 : Reset command: Do hardware reset | |
173 | len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767) | |
174 | len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms | |
175 | ||
176 | For the RESET and WAIT commands, the two following bytes will contain | |
177 | immediately the length of the following transaction. | |
