Additional Tips:
Use an oscilloscope: Always use an oscilloscope to monitor the crystal’s output signal. This will help you determine if the crystal is oscillating correctly. Firmware Debugging: If you have access to debugging tools, check the STM8S207CBT6’s register values to ensure that the external oscillator is selected as the clock source. External Interference: Ensure that there are no sources of electromagnetic interference ( EMI ) close to the crystal that could affect its performance.By following this step-by-step troubleshooting guide, you should be able to identify and resolve issues with the external crystal oscillator on the STM8S207CBT6.
