Description
Current ST7789 Driver code takes around 20.18 ms to push prepared frame buffer. which results in refresh rate locked to 49.57 FPS at 80MHz SPI Clock. Engine is capable of rendering complex scenes with lot of sprites at >100FPS so there is lot of wasted potential, Currently we are facing bottleneck in driver itself. I think we should now try to optimize driver and implement mechanism with DMA to push data as fast as possible.
