This changes was tested on a Teensy 3.2 running at 96 MHz and using the native SPI interface. That speed usually result in garbage on the OLED screen. Using a SPI transaction to limit the speed of the communication result in a correct display.

hiya we just tested latest version on teensy 3.6 so we think our SPI refactor has fixed it,
