I’m trying to use the ELO touchscreen driver.
I try to start the ELO driver with
devi-elo smartset fd -d/dev/ser1 abs -c
to calibrate it (the -c says to calibrate it)
The driver responds with “cannot open calibration file…”
When I try to run the calibration utility (Calib) without the driver
running, the calib program doesn’t seem to respond (I had \to reboot to
kill calib), but I can’t run the driver because I don’t have a
calibration file! What do I do?
