Hi folks,
I've recently discovered an interesting little 240x240 IPS display module based on the ST7789V.After hacking out the CS pin, this thing worked well with the ATSAMD21-based Arduino boards and the new Adafruit library. After discovering this library by pantata
which has DMA support for the ATSAMD21 chip I was quite impressed with the drawing speed it can acheive. Unfortunately the pantata lib was written for the ILI9341 controller and therefore contains the wrong init sequence, which leads to incorrect color representations and wrong width and height values. I tried to combine both libraries, first trying to taylor Adafruit's init sequence and the accompanying readout function into the pantata code, but failed. Trying to incorporate the DMA-relevant functions into the Adafruit library also failed.
Does anybody have experience with manipulating DMA-based tft libraries and could possibly helb me out? I can imagine that the solution is not that complicated...
Greetings,
AJ
I just got a couple of these displays and I'm trying to get them to work and have scratching my head re: the CS pin. Looks like you're further ahead, what do you mean by 'hacking out' the CS pin?
