Hi.
I can't initialize faster then SPI_DIV6_SPEED, but even with only this speed, I get double the speed in slideshow that I had previously. My tft is ITDB32WD (400x240), and I load a full image in 0.37s. Without DMAC, it tooks 0.70s.
Thank you very much!!!
But about speed, how do you have it wired to be able to handle 42Mhz?
