Well, there is the OWFS sources. I can help you understanding the sources.
The relevant code for reading the DS2423 counter pages is in
owfs/module/owlib/src/c/ow_memory.c, line 142ff and
owfs/module/owlib/src/include/ow_transaction.h:
Actually, after selecting the DS2423 chip (e.g. by doing Match ROM + 1W
address) owfs writes 3 bytes
0x00 0xa5 (read memory+counter)
0x01 address low byte
0x02 address high byte
then reads 11 bytes
0x03 throw_away
0x04 data0
0x05 data1
0x06 data2
0x07 data3
0x08 data4
0x09 data5
0x0a data6
0x0b data7
0x0c CRC16 low byte
0x0d CRC16 high byte
Maybe you missed the throw_away byte in your implementation? I vaguely
remember others which had the same problem.
Kind regards
Jan
