/* ---------------------------------------------------------- README ------------------------------------------------
* This doc is aimed at explain some important code block and do some records for the test result, if developer or
* test-owner has some question in reading this code implementation, please read it first.
*
* CODE Block:
* `code-block-1`: Touch Element lib need some time to finish the initialization so as to configure the right threshold.
* Since some hardware issue(Must to pass 2 times "meas_done" interrupt), Touch Element lib will spend
* some time(Maybe <30ms) to finish the initialization, every operations (interrupts) happen to touch
* sensor will be ignored before initialization. That's why "vTaskDelay()" could be saw in after call
* "touch_element_start()". However, this just for the unit test, in the real application, users don't
* need to delay something.
*
* NOTES:
* `Simulator`: Currently the event simulator depend on the touch sensor driver and play some "hack" in some register so
* as to raise a FAKE interrupt. It means that Touch Element lib test case must be burned on dev-kit and keep
* the touch channel as clean as possible, ESP32-S2-Saola is good test board. //TODO: Remove the dependent of touch sensor driver.
