STM32 and ILI9488, ILI9341 TFT LCD touch displays

Описание: This functions library, for STM32 under HAL, handles SPI touch displays driven by ILI9341 (320x240 displays) and ILI9488 (480x320), having XPT2046 touch sensor driver.
Library provides fast data transfer to display and touch sensor poll. That will let an efficient integration to TouchGFX GUI framework.
