I have had 1-wire devices set up and working successfully for some years but have problems with a new Louis Swart 20x4 LCD.
My setup is a Sheepwalk Electronics DS2482-800 i2c based RPI3 host adapter on a Raspberry Pi2 currently running raspbian jessie and default owfs-2.9p8. Logging/control is with fhem, a perl based home automation application. Connecting the LCD to the bus correctly identifies it. I can send text strings to it but it misses the first character and adds || to the end eg. sending fred displays red||. In order to turn the backlight on I have to send two digits such as 11, a single 1 is ignored. A net search reveals a few similar scattered reports but no solution as far as I can see. I have set up another Pi with an earlier 26 pin version of the same host adapter. A raspbian jessie install (owfs-2.9p8) shows the same as above - to be expected. A raspbian wheezy install (default owfs-2.8p15) shows all characters sent correctly, with no trailing ||. Replacing owfs-2.9p8 files with owfs-2.8p15 versions on jessie shows all characters sent correctly, with no trailing ||. I have also tried armhf owfs-3.1p1-2 versions on jessie but that shows the same issues as owfs-2.9p8 I borrowed a perl script from elsewhere on this list, running it from an AMD jessie desktop to the Pi server produces the same results as above ie. owfs-2.8p15 OK, owfs-2.9p8 amd owfs-3.1p1-2 not OK. I don't have any hardware to set up 1-wire on anything other than the Pi unfortunately. Any thoughts on where I should go from here?
