Chip Select with GPIO

[Ukoolele]

Hi,

I am using a Sparkfun nRF52832 Breakout board with the Arduino IDE. My objective is to control 3 SPI digital potentiometer. The problem is I don't know how to select the Chip Select pins (one for each potentiometer). I read on the DevZone I have to use a GPIO pin but how I can configure it ?

In general, I don't understand how to use SPI with this chip. Can anyone help me ?

Bye !

You mean this: https://www.sparkfun.com/products/13990 ?

If you're using the Arduino IDE, that has nothing to do with Nordic - so you will have to ask in the appropriate forum for that.

The Arduino Blink example on Sparkfun's "Hookup Guide" page uses GPIOs:
