If the current file offset is at or past the end of file, no bytes are read, and read() returns. The other channels are OK, but incidentally the driver tests the channel 0 upon device activation. At this stage it should be possible to set the pins of the PCF chip with the I2Cset command (didn't try if its possible to read - i2cget - but it should work fine as well). I made some tests with i2cget and i2cset and I found I have two channels, 0 and 4 (corresponding to w1_bus_master1 and w1_bus_master5 in Linux), which give Logic Level 0 upon reset of the device, hence a status of 0x10 and not 0x18. com> 4CA37C1C.
