[Solved] How to use SPI?


What SPI pins are the default from the BLE Nano? SPI0 or SPI1?
Have I use any resistors for pullup/pulldown?

I am trying to run waveshare epaper but without success.

Please help :confused:


Hi andreisk,
In the pin_map you can see Nano2 use SPI0 as default.


I am using shiftOut instead of SPI now. It’s working.
