Hello ; We use internal temperature sensor of microcontroller . When we use just internal temperature sensor code we get true adc values and degrees . In our project we do pull-up for some pins . When we pull-up with (for example) " pinMode(PE_3, INPUT_PULLUP); " we get wrong adc values . If we dont pull-up , ADC is working true . Is ADC effected from pins or what is a problem ? Does anyone have idea ? Sincereley
