WSOD fix - slow down spi #108

Closed bentumbler closed 1 year ago

bentumbler commented 1 year ago

Re-Adding the SPI clock management at 2MHz to prevent white screens. (likely artefact of bus errors at default speed of 8MHz). Lower clock speed does not produce a white screen during testing.

Test results of different clocks 8MHz (default) - Regular WSOD 4MHz - 1 in 5 WSOD 2MHz - None seen in 20 restarts
