Finally after some month I run my little board
Check it out!
SPI overclocked to 40MHz
Nice done, thank you for share, I have run the ST7789’s spi at 90 Mhz and works just fine. I also have tried 120Mhz, but it have had some issues and artifacts.
Do you use DMA in
I use default settings. Just increase a buffer to 32Kb
As I see in lvgl_spi_driver_init
esp_err_t ret = spi_bus_initialize(host, &buscfg, dma_channel);
Do you know the SPI frequency? I thought it should be a little bit faster on 240x240.
I tried 80MHz and it run faster. Kinda more smooth
