Arduino-ESP32 has modified the Mbed TLS library so that it uses ESP32 hardware acceleration. However, there is a 512-byte limit to the size of the variables used in an exponential modulo calculation. One of the steps in the SRP code used a 768-byte variable, which cannot be handled in version 2.0.0 though it works fine in version 1.0.6. Solution was to simply reduce the 768-byte variable by modulo N prior to performing the exponential modulo calculation.
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.
Simplified enableAutoStartAP() so it no longer takes any arguments. It now simply enables the auto launch of the WiFi Access Point at start-up if WiFi Credentials are not found.
New method setApFunction() will now be used to set an alternative method for the WiFi Access Point. This will be called anytime 'A' is typed into the CLI, which also covers the auto-launch of the AP at start-up a well as starting it via the Control Button, since both of these functions call processCommand('A').
