Not with SAADC, but there is a nrfx PPI/DPPI sample in the Zephyr repository.

Hello,

Is there any working example code for this? I am having the same issue.

Thanks!

Skim.

Hi,

You need to remove the inclusion of the old PPI peripheral driver from your main.c file, as PPI is not present/supported on nRF5340:

//#include <nrfx_ppi.h>

You also need to change the nrfx_ppi APIs used in the application to use the nrfx_dppi driver APIs. Another option is to use the nrfx_gppi helper API (Generic PPI Layer), which provides a common API that can be used with both PPI and DPPI.

Best regards,
Jørgen
