Also to put it into context why DMA is important, on the AtMega2560 arduino with the same display + i2c backpack the delays inherent to the HD controller meant the...

Sounds plausable. I2C using a NRF52. I work around it by DMA'ing a row in 4 goes with a timer and counter. You should be able to easily replicate it,...

I generally use Arduino as a last resort, but since the firmware is embedded I don't see why you can't implement and include a patch file (in the rare case...

I2C, NRF52. I currently implement a screen buffer of 4x20 bytes which I write to and push out to the display. Apart from the other issue that I mentioned in...

Time for a version 2.0 then. Solve all these problems and you have a one stop product for more professional use cases (DMA). ;)
