I am using the board STM32F030R8, and I am trying to measure the voltage of two different ADC channels, one at a time. The fuction SendByte is for a multiplexer, then I have to measure some voltage, the two channels are measuring different parts of t...

I want to decrease the reference voltage of the ADC to have a better resolution, is it possible to do it?Could someone explain me how can I do this? I am using the Nucleo-64 board STM32F030R8 and CubeMX to generate the code. Do I have to configure so...

I do not know if and what I am doing wrong. I am using CubeMX and a Nucleo 64-Board. This is the while inside the main:while (1) { if(HAL_ADC_PollForConversion(&hadc, 1000) == HAL_OK){ adc_value[i] = HAL_ADC_GetValue(&hadc); media += ((f...
