i'm trying to extend the capabilities of the Sparkfun SAMD21. My question is, which pins do I have to share? I mean, I understand that MISO, MOSI and SCK are shared, but CS connects each to a different pin, am I correct?
I connect my CS_RAM to the D10(PA18 on SAMD21). and i connect my CS_FLASH to the D6(PA20 on SAMD21)
