Resolved! My ADC outputs values from 970 and above
I 'm making a voltmeter - amp meter, this one...I 'm using an STM32F030K6T6.But when nothing is connected to the input, instead of outputing 0, the ADC gives me a value around 980.VDDA is tied to VDD.Boot0 is tied to GND.These are the ADC 's settings...
