Can you shed a light on the road map here. I have the SPI panel (tiny) based on the ILI9341 and I'm using actually mi0283qt driver. With yours we will have 3 (three!) drivers for the same chip. I really do not want this. Without road map on the prospective of these all drivers, NAK. -- With Best Regards, Andy Shevchenko
