https://devzone.nordicsemi.com/f/nordic-q-a/125977/ppi-not-initiating-spiI&#39;ve got an example code to turn on an LED with a button, it works. When I change it to send an spi command, it doesn&#39;t work anymore. Could you check if you see something I did wrong with SPI? I&#39;ve been around this issue for a day.
