Summary Touch Sensor refactoring to be based on IDF 4.4. Adds support to ESP32S2 and future ESP32S3. Adds some new APIs: For all chips: void touchAttachInterruptArg(uint8_t pin, void (*userFunc)(void*), void *arg, uint32_t threshold); This function allows the user to add and pass a void* parameter to the ISR user callback. void touchDetachInterrupt(uint8_t pin); This function detaches ISR call back for the touch pad pin. Only ESP32 chip void touchInterruptSetThresholdDirection(bool mustbeLower); This function allows the user to set if the ISR callback will be activated when the touch sensor readings are lower or higher than the threshold defined. See example TouchButton.ino. Only ESP32-S2 and ESP32-S3 chips bool touchInterruptGetLastStatus(uint8_t pin); This function reports if the touch pad pin is touched or untouched. It can be used with ISR to identify when it is touched and untouched (released). See example TouchButtonV2.ino. Impact None. ll original APIs and examples now run on ESP32 and ESP32-S2.
