as far as I know the Rpi board cannot be programmed to work as an SPI Master. I am wondering if the novel CM3, having more signals routed on the connector, can instead behave as an SPI Master. Any advice ?
Moreover, up to now I have programmed the Rpi SPI in C by means of the bcm2835 library by Mike McCauley. Does this library still work with the BCM2837 of the CM3 ? Any other programming option ?
Many thanks in advance,
