The TSC2100EVM is designed to demonstrate the features of the TSC2100 touch screen controller. One feature of the controller is the use of an SPI interface to communicate to a host processor. In addition, a mono-output/stereo-output audio codec in the TSC2100, communicates audio data over an I2S bus. The EVM accesses both of these busses through the use of a USB microcontroller, which provides a way to generate data for both buses from a PC running WindowsTM 98SE, 2000,or XP.
