https://devzone.nordicsemi.com/f/nordic-q-a/126535/spi-neopixel-required-clockhello, I have a neo pixel running on my nrf52840 using SPI. I still require the SPI clock pin to be configured to a pin even though it is unused. This wastes a pin, is there a way round this?

I do like contributing to zephyr so might be a fun side quest when I&#39;m free,&nbsp; I may look into the PWM peripheral for this.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/558787?ContentTypeID=1Thu, 15 Jan 2026 11:29:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f4281c9-f8b8-4204-b9d6-2626bf906a30Turbo J<p>Nopers. The SPIM refuses to work when it can&#39;t clock out the SCK signal.</p> <p>Probably a good idea to write a driver for the ws2812 LED stuff that actually uses the PWM peripherial properly, but I don&#39;t see one yet. If you really needed to save that one pin, that would be your task to do here...</p><div style="clear:both;"></div>
