This user's guide describes the operation of the TSC2117EVM-K evaluation module (EVM). The EVM
features a TSC2117 touch screen controller with stereo audio codec, amplifiers for speakers and
headphones and a digital signal processing module. Together with the USB-MODEVM board, the
TSC2117 Control Software and a PC running Windows™ XP it is a plug-and-play solution to evaluate the
capabilities of the TSC2117.
