~160 fps update rate. Shifting right by 1pixel each frame. 128px wide.
Checked SPI output on logic analyzer. 166 frames of data being clocked in each second on 3MHz SPI bus. Turned up refresh rate on OLED driver and tried 12MHz SPI and its about twice as fast (there’s some overhead in the PIC before sending out each byte… it’s running at 12MIPS = 48Mhz clock / 4). 12Mhz violates the min clock width in the OLED driver specs but it seems to work fine
