NodeMcu v2 - app does not show correct state on GPIO when it INPUT_PULLUP

Need Help With My Project

Never said it won’t work… just basically pointing out that some pins have peculiar issues.

As for the Sonoff Basic, no problem using the built-in button on GPIO0.

I have some Blynkified Sonoff code here that I started with, but it does have some issues with “switch bounce”.

I have since then improved with more reliable anti-bounce code that I found in the tubes, for said button… but all mine now work on Virtuino instead of Blynk, so that is the only code I have handy and do not feel up to editing and testing my existing Blynk code right now.

But here is a snippet of the button monitoring with anti-bounce that you can probably merge if desired…

uint32_t start, dbStart;
const byte pysBtn = 0, led = 13, rly = 12, dbTime = 15;
bool pinState = true,
     btnState = true,
     prevBtnState = true,
     latch = false;

  pinMode(pysBtn, INPUT);  // Button
  pinMode(rly, OUTPUT);  // Relay
  pinMode(led, OUTPUT);  // LED

void PhysButton() {
// Monitor and Debounce Physical Button
  if (digitalRead(pysBtn) != pinState) {  // get state of GPIO 0
    dbStart = millis();      // reset db timer
    pinState = !pinState;    // now they are equal, won't enter
  }                          // here again unless pin state changes
  if (millis() - dbStart > dbTime) {  // db timer has elapsed
    btnState = pinState;  // button state is valid
  }
  if (btnState != prevBtnState && btnState == HIGH) { // btnState changed
    // if button pressed and NOT latched
    if (!latch) {
      latch = true;    // prevents entry while latched
      digitalWrite(led, HIGH);  // LED ON
      digitalWrite(rly, LOW);  // Relay OFF
    } else {
      // if button pressed while latched,
      latch = false;
      digitalWrite(led, LOW);  // LED OFF
      digitalWrite(rly, HIGH);  // Relay ON
    }
    if (latch) {
      V_memory[1] = 1;  // Update Virtuino Button Widget ON
    } else {
      V_memory[1] = 0;  // Update Virtuino Button Widget OFF
    }
  }
  prevBtnState = btnState;
}
