    I have never used an STmcu before and I was wodnering how the 10-bit ADC's are configured. I am trying to determine the conversion time adn i can't seem to find any information i nthe datasheets.

    thanks

    The ADC conversion time is always marked in the electrical characteristics section at the end of the datasheet. Which S7 datasheet have you got?

    I found in the ST7 user manual that it takes 64 clock cycles- clock cycles being the core clock frequency of the device. I am using a 4MHz resonator.

    Please refer the section ''10-bit ADC characteristics'' in the datasheet.
