hi all, sorry i have been off for a while, been rather busy.
i have a question/issue:
when i use legacy SPI on my teensy 3.2 to drive a SSD1351 oled screen, it works
but when i try to implement a DMA based solution, it fails.
is it that the SSD1351 doesn't like DMA or is it my code that doesn't work? (i hope it's the second, although i couldn't find a issue)
the zip files containing every bit of code i have is in the zip files (SSD1351.zip works, the SSD1351_dma.zip doesn't)

the oled with breakout board i'm using is: www.ebay.com/itm/160897462664
anyone knows what's wrong? :S
