What is the difference between pulsein=True and pulsein=False? #100

I'm using it on pi 5 and i disabled pusein since the 2rd executing issue still persist. As example shows the usage of pulsein=False i can confirm that this fixes the 2rd executing issue.

I just want to know the difference between pulsein=Ture and pulsein=False How does it work when pulsein=False? I've read that pulseio is the main component that does most of work of reading IR receiver pulses then how does it read without pulseio?

It reads the pulses by polling the data pin: https://github.com/adafruit/Adafruit_CircuitPython_DHT/blob/cec6795c87c32624946994664cdce4332ca0b44e/adafruit_dht.py#L151.

Could you explain what you mean by the "2rd executing issue"? Is there an open issue that is what you mean?
