Duncan McIntyre / UniGraphic

My controller identifies as an ILI9328, but only works if initialised as an ILI9325. This fork includes a fix to force 9325 initialization when a 9328 is detected.

Revision:
34:091b954c3205
Parent:
31:4d15eb940be7 
Updated to include latest changes from upstream

Added a class to provide an interface for my MINI-STM32-V3.0 board.

This class uses direct GPIO access to achieve decent update speeds.
