I am experiencing an issue with the STM32 microcontroller used in a Battery Management System (BMS) application.
Issue Details:
- I am using ADC to measure Temperature using NTC and voltage.
- When a specific GPIO pin is detected as HIGH, all ADC channel values get stuck at the same reading.
- The issue is resolved only after resetting the microcontroller.
- This behaviour occurs randomly and is not consistent across all boards, making it difficult to reproduce.
- I am using FreeRTOS in the microcontroller.
Additional Information:
- The system is running FreeRTOS.
- I am using channels 5 to 16 on ADC1.
- ADC configuration: Sampling time is set to 24.5 cycles, and the mode is Single-Ended.
- A filtering circuit is connected to the GPIO to handle noise and transients.
Has anyone encountered a similar issue or could provide guidance on debugging this problem? Any advice on potential root causes or solutions would be greatly appreciated.
Thank you!
