OK. I try to modify a config file with the Modus addresses of the PAC. I think the development is better on a Linux machine. Later i like to use...

This solution ist flexible: int row_offsets[] = { 0x00, 0x40, _cols, 0x40 + _cols };

PAC2200 is in the device list

on my Raspi is the folder /sys/class/backlight/10-0045/actual_brightness. I change the three folder in the timeout.c and do a new make and it's work
