This page details the installation and the usage of the Linux drivers for the TSC210x chips (touch & temp/voltage control). Sound (ALSA) specific part can be found here.
Contents
Driver Installation
These drivers are now installed by default in standard Armadeus rootfs. Here you will find instructions to know how we configured Linux to activate these drivers (may be useful if you want to deactivate them).
Architecture
Usage
- Load all the needed drivers:
# modprobe tsc2102_ts TI TSC210x driver initializing TSC2101 detected input: TSC210x Touchscreen as /devices/platform/mxc_spi.1/spi1.0/tsc210x-ts/input/input0 TSC210x Touchscreen driver initialized
Touchscreen
Before use, 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 functionality; touch the screen and check that tsc2102 interrupts count is increasing:
# cat /proc/interrupts CPU0 26: 0 MPU IMX-uart 29: 17 MPU IMX-uart 30: 22 MPU IMX-uart 35: 12 MPU imx-mmc 39: 14 MPU I2C_IMX 40: 16 MPU imx-spi.2 41: 0 MPU imx-spi.1 59: 3682 MPU i.MX Timer Tick 60: 0 MPU DMA 61: 0 MPU DMA 110: 0 GPIO eth0 168: 0 GPIO tsc2102 <<<<-------- Err: 0 #
More informations concerning the Tslib can be found here.
Audio
You can play sounds through ALSA interface.
Miscellaneous
- get temperature and voltage with hwmon (Hardware Monitoring) interface. For example, get board temperature from TSC210x:
# modprobe hwmon # cat /sys/class/hwmon/hwmon0/device/temp1_input -- result in m°C
