Pretty sure that the SAADC example in the SDK uses 3 channels ... ?

How to properly post source code:

Hi James

This GitHub example explains how to configure four different SAADC channels. Please use it as a template and modify it to work with your 6 channels.

Due to the summer holidays in Norway, our support team is understaffed this week, and delayed replies must be expected. Sorry for the inconvenience!

Best regards,

Simon
