Capacitive touch screen driver board

Overview

CH55 touch button capacitance detection, 3 sets of timers and signal capture and PWM, dual asynchronous serial ports, SPI and other functional modules support USB-Host host mode and USB-Device device mode. This project uses the CH554G chip. After burning the program, it can be driven. The GT series universal touch capacitive screen is low-priced and driver-free for WINDOWS, Android Linux, etc., and the effect is good!
