I'm working on page 30 of the STM tutorial for the B-G474E-DPOW discovery kit at this link

https://www.st.com/resource/en/application_note/dm00706304-buck-current-mode-with-the-bg474edpow1-discovery-kit-stmicroelectronics.pdf

 

I get this warning when I try to follow the directions

Can someone explain how to fix this so I can move to the next step in the tutorial.

I've tried looking up codegen in the reference manual and also how to manipulate ADC12.

Thanks

Dave

Hello @decook1110 

In order to set the [PLLP Clock] or [SYSCLK] as source Clock for the ADC12 or ADC345, just change the clock Prescaler to Asynchronous clock mode in the ADC_Settings.

Best Regards.
