Texas Instruments TSC2301EVM
The TSC2301EVM circuit board is a 6 inch by 4 inch platform that contains a 16 position key pad used to exercise the TSC2301 device. The TSC2301 is an advanced touch screen controller, which communicates to a host processor through an SPI serial interface. In addition, a full stereo audio codec is included in the TSC2301, and audio data is communicated to the device over an I2 S bus. The TSC2301EVM 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 Windows 98SE, 2000, or XP.
