Installation
$ make linux-menuconfig
Architecture
Touchscreen (tsc2102_ts.ko) | HWmon | ALSA |

TSC2102 Main driver (tsc2102.ko) | ||
Linux API |
Usage
# insmod /mnt/host/lib/modules/spi_imx.ko # insmod /mnt/host/lib/modules/tsc2102.ko # insmod /mnt/host/lib/modules/evdev.ko # insmod /mnt/host/lib/modules/tsc2102_ts.ko
Then:
- get temperature and voltage with Hwmon interface:
- use touchscreen interface with tslib
- play sounds through ALSA interface: http://www.alsa-project.org/
Quick test
To quickly check driver fonctionnality, 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 #
