It's possible to make some changes to the configuration of the CPT devices to aid in incremental improvement in the capacitive sensing performance:

1. Increase the oversampling OR reduce the Debounce to 2 or 1

2. Make sure that the touch delta is as per the new board revision

  • Touch Delta = closest multiple of 16 of [Active Threshold - Inactive Threshold])
  • Threshold values can be found in the Capacitive Sense Profiler

3. Active mode scan type should be set to "Free Run Mode"
