Debian system
Calibrating the touchscreen
$ TSLIB_TSDEVICE=/dev/input/event0 ts_calibrate
Running example Qt Apps
Run demos with touch-screen as input device:
$ QWS_MOUSE_PROTO=Tslib:/dev/input/event0 /usr/qt/demos/demoname/demoname -qws For the Qt-Browser change demoname to browser
Run demos with a usb-mouse as input device:
$ QWS_MOUSE_PROTO=Auto:/dev/input/mice /usr/qt/demos/demoname/demoname -qws
Login/Shutdown system
Login: Name: root password: foo Shutdown: $ shutdown -h now
How to control the GPIOs

- Export
echo <GPIO#> >/sys/class/gpio/export
- Set direction
echo in >/sys/class/gpio/gpioXX/directionecho out >/sys/class/gpio/gpioXX/direction
Initialize and test CAN
Initialize: $ ip link set can0 up type can bitrate 500000 Send test message via cansend (part of can-utils): $ cansend can0 100#11.2233.44556677.88
