I am using the Teensy SPI code (https://github.com/btmcmahan) and it's working and transferring data from an Yun to the Teeny 3.1. The odd thing is th CS has to be held peramently low and switch the CS from the Yun during the SPI transfer does not seem to work.
My scope has just broke, so I cannot check the CS switching from Yun but I know it's simple GPIO switching on/off. Therefore; how does the SPI transfer work when the CS line is not switching & peramently low? or is it okay to keep the CS line low?
Many thanks
