Touch-Sensing Platform Evaluation Board
NXP's Ready Play Solutions integrate functionality to different applications, allowing customers to add features while reducing development cost, simplifying design cycles and enabling scalability in applications and systems.
NXP's EVBCRTOUCH is a low-cost development board that allows quick connection between any standard 4 and 5 wire resistive screen. The board also features four capacitive electrodes which enables a quick ramp up. The board also provides a USB-to-Serial bridge to allow a connection to any host processor or PC via USB.
CRTouch is a resistive touch screen controller that enables 4-wire resistive touch screens to handle basic gesture recognition. CRTouch allows also the addition of up to four capacitive electrodes to your system. It supports 4-wire and 5-wire touch screens and communicates over UART and IC communication protocols.
