Hello Nordic community,
I’m working on a project with the nRF52840 DK (PCA10056) using the nRF5 SDK and the S140 SoftDevice. My goal is to:
1. Read two NTC thermistors...
I am trying to write SPI code for the nRF52840 dongle. Since the nRF5 SDK does not directly provide an example for the dongle, I followed the steps defined in this tutorial...
I am trying to build using a custom board and 2.9.1, but am getting these errors:
My dts looks like this:
I have the width specified. Much of this is over...
Dear Nordic,
We’re working on a Smart Door Lock project built on custom hardware that includes an nRF5340 and several other controllers. For firmware updates, we’ve adopted...

Hi,
I have written SD & SDHC card routine for reading, writing and erasing data from SD card. It used the hardware SPI of nRF51822.
NOTE:
1)Define the PINs of SD card first before initialing.
2)Define…
