Changing size of display buffer #305

Closed dlugaz closed 2 years ago

dlugaz commented 2 years ago

I wanted to increase the size of display buffer and change it to single buffered (from double buffered). I'm using ILI9488 via SPI. I changed the DISP_BUF_SIZE to 60*480. Code compiles, there is enough memory, buffers are declared static.

#elif defined CONFIG_LV_TFT_DISPLAY_CONTROLLER_ILI9488
#define DISP_BUF_SIZE  (LV_HOR_RES_MAX * 60)

static DMA_ATTR lv_color_t buf1[DISP_BUF_SIZE];

Code runs, but the display is ruptured. Looks as if only some of the buffers and sent correctly photo

Do you have any idea why this can happen?
