Hi,
I'm porting an application from nRF5 SDK (v16.0.0) to nRF Connect SDK (v2.9.0) to be able to work with the nRF54L15. While porting our ADC functionality, I noticed that it seems that not all gain settings mentioned in the datasheet seem to be supported (yet?) in Zephyr/ncs, specifically 2/4, 2/6, 2/7 and 2/8. Since it's just a matter of setting a value to a register, I was wondering how the mapping of ADC gains is done on the nRF54L15 in our version of the SDK?
Is it just a matter of setting the mathematical equivalent (e.g. instead of GAIN_2_6 which is not supported, use the supported GAIN_1_3)? And if that's the case, how would you be able to use the 2/7gain? Not that we use it, but I just feel that this may be a documentation issue.
Best,
Wout
