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 (Hardware Monitoring) interface,
  • use touchscreen interface with tslib API,
  • play sounds through ALSA interface

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
