I am relatively new to working with ESP32 devices and am experiencing an issue with the touchpad on one of my ESP32 boards. Here are the details:
Problem Description
Wake-Up Difficulty: The touchpad does not reliably wake the device unless I am touching a large metal object.
Observations
Touching Metal: When I touch a large metal object while attempting to wake the device, it reliably wakes up, suggesting that the touchpad’s sensitivity is significantly improved with this additional capacitance.
Consistency Across Devices: The same code works perfectly on other ESP32 devices of the same model, but not on this specific device.
Steps Taken
Adjusted Sensitivity: I have tried adjusting the touchpad sensitivity settings in the configuration.
Ensured Proper Grounding: Made sure that the device is properly grounded.
Request
Given my inexperience, could someone please provide guidance on what might be causing this issue with this specific device and how I can resolve it? Any insights or recommended practices for improving the touchpad’s sensitivity and reliability would be greatly appreciated.
Thank you for your assistance!
