Implementation of digitalFASTread() possibility

[JoJos1220]

I wanted to avoid digitalRead()/digitalWrite() operation within my Project. Therefore I made a split-up of the tick() function - to enable the possibility to read the Encoder-State within my loop function and the usage of a digitalFASTread() Operation and overload it to the tick function directly.

I made successfull Comissioning on ESP32-WROOM by implementing: encoder.tick(digitalFASTRead(encoderPinB), digitalFASTRead(encoderPinA)); Instead of: encoder.tick(); And it worked to me perfectly. My used digitalFASTREAD() function I used is: /*-----------------------------------------------------------------------------

• digitalFASTRead(): Function to read a GPIO Pin State as fast alternative to digitalRead()

• ---

  */ int digitalFASTRead(uint8_t pin) { if (pin < 0 || pin >= 40) { // Pinnumber outside of valid area! return false; }

  uint32_t bit = digitalPinToBitMask(pin); uint32_t port = digitalPinToPort(pin);

  if (port == NOT_A_PIN) { // Invalid Pinnumber return false; }

  // Pointer on GPIO-Register volatile uint32_t *reg = portInputRegister(port);

  // Read Pin State bool state = ((*reg) & bit) != 0;

  return state; }
