Himax HX8357-D display panel. 24bpp/RGB888 only. No ESP-IDF esp_lcd component exists for this
|
|
controller, so this driver speaks the panel's raw SPI command protocol directly (bit-banged
|
|
DC line, blocking spi_device_transmit()) rather than wrapping esp_lcd_panel_io/esp_lcd_panel.
|
|
No bgr-order property: unlike the RGB565 panels (ili9341-module, st7789-module), there is no
|
|
DISPLAY_COLOR_FORMAT_BGR888 in the kernel model, so a BGR-wired panel isn't representable here.
