Minimize Signal Noise

ADC performance can be heavily affected by external noise on the analog input signal.

Solution: Use proper grounding and shielding techniques to reduce noise. You may also add a small capacitor (e.g., 100nF) between the input pin and ground to filter high-frequency noise.

Conclusion:

By following these steps, you can effectively diagnose and resolve issues with the STM32F051C8T6 ADC not working. Start by checking the configuration of the ADC, clock settings, GPIO pin modes, and power supply. Make adjustments based on the recommendations provided to ensure stable and accurate ADC operation.
