Hi,
I've made a board under assumption that any digital pin can be used as chip select pin (my board uses 14 digital pins for 14 NOR flash modules). Unfortunately, it doesn't work at all. I've tried setting all 14 HIGH before SPI.begin(). But they refuse to work together. In the SPI library code there is only one CS pin for T4.0.
I'm wondering what the problem is and if there is a way to use my 14 CS pins...
Thanks.
