Is there any sample code for doing a 14-bit differential voltage measurement across two pins?

[David Fogelsong]

The only examples I've found have been for ordinary single ended measurements at lower resolution, and even that is a crazy number of lines of code.  Surely by now there is an API which makes it all simple?

Use NRFX_SAADC_DEFAULT_CHANNEL_CONFIG_DIFFERENTIAL and nrfx_saadc_init with a nrfx_saadc_config_t where the resolution set to 14-bit.

I don't understand.  In what sample code?  Please elaborate.

Use the SAADC example and our API documentation.
