RA8875 seems that does not work with lvgl. Something is problematic with the setup i suppose. The problems that i have is the one presented but not solved in the github issue
As summary in my case i just have black screen.
When using SIO and full-duplex the memory clear operation times out, which warns the controller may be unresponsive except if the SPI frequency small like 1MHz where not error comes but program does nothing expect logging the it Enables Display.
When using DIO/QIO and half-duplex, the error about DMA comes up
Someone else is saying that there is problem with SPI Mode where there is not setup for RA8875 in lvgl_spi_conf.h so program takes SPI Mode 0. He says that proper mode is 3 but i do not see also this working
#if defined (CONFIG_LV_TFT_DISPLAY_CONTROLLER_ST7789) #define SPI_TFT_SPI_MODE (2) #else #define SPI_TFT_SPI_MODE (0) #endif
I am using v4.3 esp-idf and the lv_esp32_port example to check how it works.
Is there any solution cause the github issue is closed before one year
