    Hi Bruno,

    I don't understand what do you mean by impossible to use ADC on several Channels....

    I have update your code to use the Potentiometer (RV1) channel9, the microphone as external analog input channel11 (U8) and the BNC connector as external analog input channel12 (CN3) and it works fine

    You can find attached the project updated

    Regards

    mozra

    Hi Mozra,

    I have found the problem: The VREF+ and VREF- pins were left unconnected on my STM8, so ADC was measuring the entropy of the universe.

    Thanks for your help,

    Bruno
