CskZoli Posted August 5, 2023 Report Share Posted August 5, 2023 Dear All, Created an SPI variant of ILI9488 display driver. In SPI mode only RGB666 mode available, so init code was modified accordingly. Added HARDWARE_FILLS and HARDWARE_BITFILLS functionality with DMA using a small intermediate buffer (this gives a ~2x speed improvement, and CPU offload at a cost of few hundred bytes of memory). This "hack" can be implemented on other SPI based display, even with non standard RGB565 pixel format. Also added PWM backlight contolol. Tested on STM32F401 with ChibiOS 21.11 Please feel free to use it... Cheers ILI9488_SPI.zip Link to comment Share on other sites More sharing options...
