Web2 Handmade_Octopus • 2 yr. ago I managed to get quite fast refresh rates on LVGL using DMA and double buffer with tft_espi over 80 Mhz. Of course 3.5" is too much as ili9486 doesn't support DMA but you can get 3.2" ili9341 with DMA support. Used it in my project and I am mostly happy with this library! 5 andyrocks • 2 yr. ago http://www.iotword.com/7840.html

WebFeb 13, 2024 · As far as I can see ( weefnn / pandora, if this is the code you use), the function LCD_Send_Data_DMA is hard coded for 16-bit pixel (two bytes) as you can see in line 636. That means, if you use 8-bit pixels, the function LCD_Send_Data_DMA may write more pixels as the buf2_1 provides. http://www.iotword.com/8030.html
