NewPing not working when using pins D5-D8.

Module: WeMos D1 R2 mini

CPU Frequency: 80Mhz
Upload Using: SERIAL

Sketch

#define PIN     D6     // Not working
// #define PIN     D3     // Working

uint32_t _triggerBit = digitalPinToBitMask(PIN); // Get the port register bitmask for the pin.
volatile uint32_t *_triggerOutput = portOutputRegister(digitalPinToPort(PIN)); // Get the output port register for the pin.
volatile uint32_t *_triggerMode = (uint32_t *) portModeRegister(digitalPinToPort(PIN)); // Get the port mode register for the pin.

void setup() {
  *_triggerMode |= _triggerBit; // Set trigger pin to output.
}

void loop() {
  *_triggerOutput &= ~_triggerBit; // Set the trigger pin low
  delay(1000);
  *_triggerOutput |= _triggerBit;  // Set trigger pin high
  delay(1000);              // wait for a second
}

pinMode(PIN,OUTPUT);
works

*_triggerMode |= _triggerBit;
does not

I am also having trouble doing the same thing with a capsense sketch I am testing.

On the esp don't you have to set gpio mode also ? I do not see how this is being done,I tried debugging this but once i got to the register definitions I was lost...

@vermut please use pinMode instead of the low level register handling.
This looks like user error to me, closing.
