STM32F303 Discovery board ADC offset
Posted on June 13, 2013 at 09:18Hi, I've configured ADC1 to sample one of the channels like PA1 (Channel 2). However, when I connect a power supply to the input, there is a large offset. For example, connecting 2V I can see around 200-250mV offset. ...
STM32F3 Discovery - ADC Offset
Posted on July 10, 2013 at 23:04I'm working on getting the ADC fully integrated with the rest of my code. When I'm testing out my ADC, however, I keep getting an output of about 300-400 from ADC1->DR when I'm inputting a voltage of 0 to the pin. I...
