Texas Instruments TSC2101EVM
The TSC2101 is an advanced touch screen controller, which communicates to a host processor through an SPI serial interface. In addition, a mono-input/stereo-output audio codec is included in the TSC2101, and audio data is communicated to the device over an I2S bus. The TSC2101EVM accesses both of these buses through the use of a USB microcontroller, which provides a way to generate data for both buses from a PC running Windows 98SE, 2000, or XP.
