Hello All ;
I use STM32f407 ; I connect Vref to VDDA to VDD ;
but VDD is connected to super cap that can be change from 2,9V to 3,5 volt ; so my ADC reading would be change ;
Does STM32F407 has internal Refence ? I did not understand that from the manual it says it has 1,2V internal reference
if yes how can ı use it ; ?
Thank you in Advanced
