Good afternoon all,I have an STM32 controlling a 320x240 LCD using an ILI9341 controller and communicating over a SPI interface. It all works perfectly, using my own interface routines, and almost works perfectly under my initial basic integration of...

Afternoon all,I got it all working, so thought I would outline it here for anyone who stumbles across this thread in the future....First off, the ST documentation is confusing when it comes to support for byte-swapping. The STM32H7 datasheet says it ...

Thanks HP - I am getting closer! I added DMA2D as an intermediate step to a secondary frame buffer that I then send to the SPI. The sequence works, and the new frame buffer is sent to the display just fine. The problem is that it does not appear to a...

Hi HP,Yes - static image test has everything where it should be, just enjoying a pretty psychedelic colour palette!I was looking at the best way to do it in my transmit. I was hoping to use DMA on SPI just to send that existing frame buffer out witho...

Hi HP,I am pretty sure (always leave room for error!). I made a test with 3 strips of pure red, green, and blue. The red and blue looked pretty close to complete swaps, but the green was a different colour altogether. As it is RGB565 if the red and b...
