105 | Basic firmware description. This will remain with | |
106 | the driver for documentation purposes. | |
107 | ||
108 | This represents an I2C firmware file encoded as a | |
109 | string of unsigned char. Format is as follows: | |
110 | ||
111 | char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB | |
112 | char[1 ]=len0_LSB -> length of first write transaction | |
113 | char[2 ]=data0 -> first byte to be sent | |
114 | char[3 ]=data1 | |
115 | char[4 ]=data2 | |
116 | char[ ]=... | |
117 | char[M ]=dataN -> last byte to be sent | |
118 | char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB | |
119 | char[M+2]=len1_LSB -> length of second write transaction | |
120 | char[M+3]=data0 | |
121 | char[M+4]=data1 | |
122 | ... | |
123 | etc. | |
124 | ||
125 | The [len] value should be interpreted as follows: | |
126 | ||
127 | len= len_MSB _ len_LSB | |
128 | len=1111_1111_1111_1111 : End of I2C_SEQUENCE | |
129 | len=0000_0000_0000_0000 : Reset command: Do hardware reset | |
130 | len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767) | |
131 | len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms | |
132 | ||
133 | For the RESET and WAIT commands, the two following bytes will contain | |
134 | immediately the length of the following transaction. | |
