Informations about the hardware interface between the i.MXL and the TSC2102. This chip will be available on the DevFull board but anyone should be able to add it to it's DevLight.
Introduction
This chip is a "SMART" 4-Wire Touch Screen Controller with Stereo DAC with HP Amplifier.
Interface
Touchscreen
Configuration and data exchange is done through the SPI bus n°
Audio
Configuration through SPI bus and data exchange through SSIA
Signals
