Hi,
I am trying to rotate the Sparkfun flexible OLED display and the library does not have this function. It can mirror horizontally and vertically but I was unable to rotate it. I looked in the datasheet for the SSD1320 here:
I had some luck with changing #define SETSTARTLINE to 0xA2 from 0xA1 and it just needed to be mirrored but at that point the flipHorizontal function did not seem to work.
I have seen several other posts trying to figure this out with no luck. Any help would be appreciated!!
