Hello!
Sorry for using an old thread, but I'm running into the same performance issue as M3Michi.
I would like to use SPI DMA in my project with STM32F4 and ili9341. I can imagine the architecture of the solution, but having an example of implementation from M3Michi I would do it much faster.
Could you please update the link to M3Michi's project or publish his implementation of the "gdisp_lld_ILI9341" driver?
I sure this example would be very useful for everyone who want to use combination of DMA and ili9341 in STM32.
Thanks for your uGFX!
