Hello, I'm back with my LiDE 90 !
I see in my windows logs the following sequence for gpios (reg 0x6C) : 02 12 0e 1a 0a 0e/3e (3e for half ccd log) (seems to be scanning moment) 0e 0a 0e/3e (3e for half ccd log) 02 With tests I identifies GPIO11 as home switch (with 1 scanner doesn't see home position any more) and GPIO14 as half CCD. But it doesn't seems to be so simple. Why windows driver plays with home switch ? Why did I have half image with GPIO13/14 to 0 ? Subsidiary question : where in the code to play to modify default 0x6C register value before calibration, before scanning and after scanning ? Regards Guillaume
