3.2" 320x240 Resistive Touch LCD (D)

This is a generic (not device-specific) resistive touch LCD from Waveshare, offering a 320x240 resolution with 256K colours. The LCD has an onboard touch control chip (XPT2046) and LCD controller (ILI9341), with an 8080 16-bit interface + SPI. It comes with online documentation covering the pinout/interfaces and includes example code for STM chips (specifically the STM32F103RCT6). Whilst hardcore programmers will enjoy figuring out the interface to use this display with various development boards, this display is likely not ideal for beginners as 'quick n easy' example code is limited. Note: this product is intended for MCUs with 2.2V~3.6V IO voltage only. Features
