Interfacing HY32D Display with MSP432

This repository contains a set of libs to interface the HY32D display using 16Bit parallel interface to the SSD1289 display controller and SPI interface to the XPT2046 touch controller.

Tasks:

• base code structure
• abstract display class
• SSD1289 interface class
• SSD1289 assembler functions for better performance
• XPT2046 touch controller interface
  • SPI read via DMA
  • measure multiple times
  • touch down detection
  • calibration
• code documentation
