Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is there a post anywhere that indicates what are the allowed speeds in the
SPI OPEN speed command.
I had a quick look in the manual but did not see anything.

The speeds that will actually be set are CPUspeed/2 divided by 1 to 256

Thanks.

Suggested update to Appendix D
  Quote  
Appendix D - SPI Communications
‘speed’ is the requested speed for the SPI clock. Any value can be requested, the firmware will select the next speed that can be achieved that is equal to or slower than the speed requested. The speed that will actually be set is CPUspeed/2 divided by 1 to 256.
