Datasheet
No Clock Signal at the SCL Pin of Sparkfun nRF52832 Breakout Board
If you are not getting a clock signal at the SCL pin of your Sparkfun nRF52832 Breakout Board, there could be several possible causes. Here are some troubleshooting steps you can follow:
1. Check your connections
Ensure that all the necessary connections between your board and the clock source (such as an external crystal oscillator or an on-board crystal) are properly made. Double-check the wiring and ensure that there are no loose or disconnected wires.
2. Verify clock configuration
Make sure that the clock configuration settings in your code or software are correctly set up for the nRF52832. Check the datasheet or reference manual for the correct settings and compare them with your code.
3. Check power supply
Insufficient or unstable power supply can cause issues with clock signals. Verify that your board is receiving a stable power supply within the recommended voltage range. You may also want to check for any power supply-related issues such as voltage drops or noise.
4. Test with a different clock source
If possible, try using a different clock source (e.g., a different crystal oscillator or a different board) to rule out any potential issues with the current clock source. This will help determine if the problem lies with the clock source or the breakout board itself.
5. Measure signal with an oscilloscope
Use an oscilloscope to directly measure the SCL pin’s signal. This will help you verify if there is indeed no clock signal or if it is too weak to be detected by other means. It can also help identify any abnormalities in the signal waveform.
6. Consult the manufacturer or community
If none of the above steps resolve the issue, consider reaching out to the manufacturer’s support or consulting relevant online communities or forums for assistance. They may have encountered similar issues before and can provide specific guidance or solutions.
