[Touch Sensor] The TOUCH_SCAN_DONE_INT Interrupt Raw Data Value Is Undefined
Description
For ESP32-S2’s touch sensor, the raw data value is undefined for the first two TOUCH_SCAN_DONE_INT interrupts.
Workarounds
Users are suggested to skip the first two TOUCH_SCAN_DONE_INT interrupts, then turn them off and stop using them.
This issue has been bypassed in all versions of ESP-IDF through this method.
This issue has been bypassed in the Touch Element component (touch_element) in ESP-IDF (introduced in ESP-IDF release version v4.3). If you are directly developing on the lower-level touch sensor driver, please follow the implementation provided within the Touch Element component and the recommendations mentioned above to bypass the issue.
