This allows the "src.ino" test file to once again properly compile without requiring modifications to any existing HomeSpan sketches. This was needed to ensure src.ino can find object code in "extras", which is now required to use the new statusDevice() method. Since the Arduino IDE only copies files that are in "src" folders, "extras" needed to be moved to "src/extras". For backwards compatibility with all other sketches, the "extras" directory now contains stubs for the ".h" include files.
Also add getPin() to RFControl (which is used by SK68XX Class) as well as boolean operator overrides for both RFControl and PwmPin/ServoPin so that instances can be checked for validity.
New IDF parameter in 2.0.0 for LEDC allows PWM signal to be inverted! Need to ensure flags.output_inverted is set to 0!
Also: Deleted old PWM class, which was saved for backwards compatibility. This "breaks" HomeSpan for those using the old PWM class (instead of LedPin).
Also: Added checks to ensure that frequency is achievable (for S2 and C3, the 14-bit duty resolution is insufficient to allow frequencies slower than 5 Hz - this is not a practical limit when using LedPin to drive actual LEDs and lights).
Should now work with ESP32-S2 and C3. Allows for as many LEDs and Servos as there are channels and timers across low and high (esp32 only) modes. Allows LED to be set with floating point precession instead of just uint8. Allows specification of LED frequency for each LED (1-65535 Hz). Automatically provides maximum duty resolution for frequency chosen.
Both classes check that total number of combined instantiations does not exceed 16. ServoPin() has additional limit of only 8 instantiations.
DEPRECATED: PwmPin(). Keep for backwards compatibility only.
TO DO: Update Tutorial Examples to replace PwmPin with LedPin, and update Extras.h documentations with LedPin and ServoPin.
This is a replacement for PwmPin(). It keeps track of channel numbers internally, which greatly simplifies the user interface. Starts by using the 8 Low Speed Timer channels and then moves to the 8 High Speed Timer channels if more than 8 LedPins are instantiated. Throws a non-fatal error if more than 16 LedPins are instantiated, and ignores any attempts to set the duty cycle of those channels.
Removed need to include channel number in set() method. Why was this ever there? Need to update Examples and PwmPin docs. But keep stub method that includes channel for backwards compatibility.
Transtioned to all getter methods: getVal(), getNewVal(), updated(), using templates for all floats.
Finalized templates for getVal and getNewVal, including making <int> default so it does not have to be set for most getVal() and getNewVal() calls. Works for booleans as well. TO DO: Re-work and check ALL prior examples to ensure they use getVal, etc., and DON'T access value, newValue, isUpdated, directly.
