Yes OK -- I will check. But as far as I know the 0xfe-answer from the touchscreen means: "Please resend the last command". And 0xfc means: "Error I didn't get that".
I also checked my original standalone-driver: Because of this behaviour I always retried the last command 3 times if the responce from the device was 0xfe or 0xfc.
