thanks for reading!
I'm using a ILI9341 2.8" LCD screen via SPI with a ATSAMD21. Using DMA with a 24Mhz SPI. I'm being able to fill screen buffer in about 60mS. So, around 18fps.. It's all good. But I'm seeing the display refresh!!! it takes like 300mS to refresh the entire display.
I'm sending a white screen, then waiting for a second, then sending a black screen, and looping this.
I attach a video...
ANY HELP OR IDEA about what's happening is more than welcomed. I don't understand. I've been researching without any luck.
