In this video, I have demonstrated how to create a simple project in CubeMX for an ADC application with multiple input channels, both internal and external one. First, we're gonna measure the chip temperature using internal temperature sensor of the STM32F0 chip. We also use the Vdd voltage that we got from previous video for our calculation. Then, an analog signal from a potential meter is measured using an ADC external input channel. The conversion result was more than I expected although there was no filtering algorithm applied. The detailed explanation will be updated at: https://letanphuc.net/2016/07/stm32f0-adc/
