DMA support #75

Closed StefanvdPas closed 8 months ago

Very nice library! But for practical usability it would greatly benefit from DMA support. Now lots CPU cycles are wasted, but worse the loop in ssd1306_UpdateScreen() burns so much time that introduces much latency in a simple round robin schedule.

Absolutely. Please feel free submitting a pull request.

Ok, let see if I can find some time. I suppose it will be handy to add a conditional compilations switch?
