This commit addes an example showing how to receive messages using the TWAI
driver interface and a CAN transceiver. Specifically, the example demonstrates:
- How to configure and install the TWAI drvier
- How to poll for TWAI events (i.e., alerts) using twai_read_alerts()
- How to handle the various events (such as TWAI_ALERT_RX_DATA)

The original code assumes 100Hz FreeRTOS tick rate and just supplies vTaskDelay with the assumed number of ticks required for the wanted delay. This patch simply fixes it to use portTICK_PERIOD_MS, thereby working correctly regardless of what tick rate FreeRTOS has been configured to run at.
* Removed option to change CHANNEL
* Revert "Removed option to change CHANNEL"
This reverts commit b2ec27de1d2d4703a15f6397550a46896413828a.
* Fixed the ability to change CHANNEL
* WiFi scan only on selected channel
* Improve RGB LED Driver
Replaces the use of the `LED_BUILTIN` variable by creating a new variable called `RGB_BUILTIN`. On boards with both a regular LED and RGB LED, this change provides functionality to control either LED.
The `LED_BRIGHTNESS` variable is changed to `RGB_BRIGHTNESS`, which aligns more closely with the `RGB_BUILTIN` variable name.
`BOARD_HAS_NEOPIXEL` is no longer necessary; it is replaced by `RGB_BUILTIN`.
* Update BlinkRGB example
Update example code for changes with the RGB driver:
- Replace `LED_BUILTIN` and `BOARD_HAS_NEOPIXEL` with `RGB_BUILTIN`
- Replace `LED_BRIGHTNESS` with `RGB_BRIGHTNESS`
* Update board variants
Update board variants for changes with the RGB driver:
- Remove `BOARD_HAS_NEOPIXEL`
- Define `RGB_BUILTIN` pin
- Replace `LED_BRIGHTNESS` with `RGB_BRIGHTNESS` to align with `RGB_BUILTIN` name

Description of Change
Original code does not work (crashing) - related issue #6832 - now fixed.
Extended description to be more helpful.
Added options to modify the setup at the top of the code via constants.
Added option do plot with Arduino Serial plotter.
Even if the crashing was solved alone the ledc PWM would not output any signal.
Tests scenarios
Tested on ESP32 with oscilloscope and signal generator.

* Initial implementation of RGB driver via digitalWrite
* Moved constants to pins_arduino.h
* Changed pin definition + added example
* Wrapped BlinkRGB in #ifdef BOARD_HAS_NEOPIXEL
* Removed forgotten log from example
* Moved RGBLedWrite to new file esp32-hal-rgb-led and created pinMode in variatn.cpp
* Updated example - lowered single channel brightness to LED_BRIGHTNESS
* Changed function name from RGBLedWrite to neopixelWrite + code polishing
* Moved pinSetup portion related to RGB back to common file
Summary
Added compiler.warning_flags to all chips in platform.txt to reflect users setting of warning level output during compilation (set up in Arduino IDE preferences)
Impact
When a warning is set to none the compilation will no longer display warnings

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.

Summary
This PR is refactoring of SigmaDelta HAL in order to use IDF instead of current Register manipulation approach.
Impact
Change in API:
uint32_t sigmaDeltaSetup(uint8_t channel, uint32_t freq);
changed to -->
uint32_t sigmaDeltaSetup(uint8_t pin, uint8_t channel, uint32_t freq);
void sigmaDeltaAttachPin(uint8_t pin); removed, no longer needed. Pin is attached in sigmaDeltaSetup()
Summary
RMT HAL refactoring based on IDF.
Impact
Improves RMT by adding IDF v4.4 support.
Receiving RMT can handle any size of data.
rmtInit() has a new parameter - RxBufferSize - to hold any number of data when receiving RMT.
rmtWrite() has a new parameter - wait_tx_done - to block writing until sending all data.

## Summary
Arduino ```setup()``` and ```loop()``` run under a Task with a fixed Stack size of 8KB.
Users may want to change this size.
This PR adds this possibility by just adding a line of code, as for example:
``` dart
ESP_LOOP_TASK_STACK_SIZE(16384);
void setup() {
}
void loop() {
}
```
## Impact
None. It adds a new functionality to ESP32 Arduino.
If ```ESP_LOOP_TASK_STACK_SIZE(newSize);``` is not declared/used, it will compile the sketch with the default stack size of 8KB.

Thanks @igrr for the suggestion!
A typographical error is corrected in the 2nd line of the comment.
From = " This is un example howto use Touch Intrrerupts "
To = " This is an example of how to use Touch Intrrerupts "
This is very much still work in progress and much more will change before the final 2.0.0
Some APIs have changed. New libraries have been added. LittleFS included.

* Add an aditional (void *) arg to the RMT callback - to allow more flexible handling of the callback (e.g. by passing a private struct or a class pointer). Same pattern as used by the Ticker() and many others. Example updated & new example with a trapoline added.
* Fix example for new API
* Fix lint warnings
* Add a second missed example.
* Correct timeout & improve socket error handling.
* ESP.getChipModel() returns model of the chip
* ESP.getChipCores() returns the core count.
* Example gives chip model, revision and core count.
* Read efuse for chipmodel

They are all broadly similar, all being based on the ESP32-D0WD core, but have
some subtle differences between variants around PSRAM inclusion and camera pin
mappings.
The ESP32CAM "unit" product (SKU: U007) has no PSRAM and maps the
"Pixel Data 0" (Y2 GPIO/OV2640 D2) camera pin to IO17 rather than IO32 as is
the case with most other M5Stack ESP32 camera devices.
The ESP32CAM also requires the "hmirror" and "vflip" camera configuration
bits setting in order to capture a true image.
The relevant M5Stack pin configuration documentation can be found here:
https://docs.m5stack.com/#/en/unit/esp32cam?id=pinmap
The boundary delimiter (_STREAM_BOUNDARY) needs to be send before the
body part (_STREAM_PART) too follow RFC2046. This caused ffplay/ffmpeg
to fail to open the MJPEG stream.
Fixed bit shift in demo application of using RMT peripheral. Init data array to be transmitted was off by one, as for the first iteration (i==0) the mask was 1<<8, which results in shifted RGB value in color variable
Closes https://github.com/espressif/arduino-esp32/issues/2921
* Properly allocate string and remove warning
The former way generates the following warning:
ISO C++ forbids converting a string constant to 'char*'
This change makes a character array the size of the string with null ending. It's clearer and gets rid of the warning.
* Better way
Since this is technically immutable, the type should reflect this too.
