TM4C1294NCPDT Internal Temperature Sensor Get Confused

Recommended Posts

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 ?
