This page details the installation and the usage of the Linux drivers for the TSC210x touchscreen & sound chip. Sound (ALSA) specific part can be found here.

[hide]Driver Installation
Drivers are now installed by default in standard Armadeus rootfs. Following instructions are only given as references or if you want to remove these drivers from your configuration.
$ make linux26-menuconfig

$ make
Then reflash your Linux kernel and your Rootfs...

Usage
- load all the needed drivers:
# modprobe tsc2102_ts TI TSC2102 driver initializing input: TSC2102 Touchscreen as /class/input/input0 TSC2102 touchscreen driver initialized
Touchscreen
Before to be used, the touchscreen has to be at least one time calibrated:
# ts_calibrate
Then it can be tested with:
# ts_test
If it does not work you can quickly check driver fonctionnality, touch the screen and check that tsc2102 interrupts count is increasing:
# cat /proc/interrupts

Audio
play sounds through ALSA interface
Miscelleanous
- get temperature and voltage with hwmon (Hardware Monitoring) interface. For example:
# modprobe hwmon # cat /sys/class/hwmon/hwmon0/device/temp1_input -- result in m°C
