I have problem with the result from ADC. I divide it into two problems and will try to describe them good below. First some facts about the design, software and ADC configuration.Device: STM32G0B1CCU6Software using: STM32CubeG0 MCU Firmware Package V...

In datasheet STM32G0B0KE/CE/RE/VE, DS13565 Rev 2, page 28/105 this can be read:"The embedded USB controller cannot be used on STM32G0B0KE as this device does not provide an HSE oscillator input."As it is written on same page "the clock source must us...

This is not a question, more like a statement and proposal to update datasheet.In these two datasheet:DS9716, STM32F401xB STM32F401xC, DS9716 Rev 11, page 105/139DS10314, STM32F411xC STM32F411xE, DocID026289 Rev 7, page 114/149It are specified sample...

Oh, now you find it. I was on the way to write this:I have not used that version, but maybe I anyway can recommend to check that the "USB, UCPD1 and UCPD2 global interrupts" is enabled, (System Core - NVIC).

I did a calibration before first measurement, after power up. However have now changed and always do it, before each measurement. The code sequence is like this:HAL_ADCEx_Calibration_Start()HAL_ADC_Start_DMA()Wait for HAL_ADC_ConvCpltCallback()HAL_AD...

- Buy a cheap bluepill, blackpill (or similar board) and "ST-LINK V2" from China.- Install STM32CubeProgrammer- Check that ST-Link can commuincate with your device, something like this: ~/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer.sh -c port=...

I found an application note that describe this and more about ADC:AN2834 How to get the best ADC accuracy in STM32 microcontrollershttps://www.st.com/resource/en/application_note/cd00211314-how-to-get-the-best-adc-accuracy-in-stm32-microcontrollers-s...
