I'm using a STM32F072 Discovery Board. I'm trying to use Channel 1 (PA_1) and Vref being supplied externally at VDDA(Pin number 13) .
I have disabled internal Vref using the function call ADC_VrefintCmd(DISABLE);
Even in register window Vrefint is not tick marked, but the ADC Count doesn't vary with the new Vref being set externally.
Kindly do the needful
