Texas Instruments TSC2100EVM
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.
