Hello, I am having the same problems with "1-wire" on IOT2040 in general. I am trying to run a temperature sensor (DS18B20) and/or a temperature-humidity sensor (DHT11) attached to an IOT2040 without success. I tried several output pins (D0 - D7), but neither of the is working. The same setup works like a charm with "arduino nano" and "esp-12f" boards. I suspect, that the GPIOs of the IOT2040 are not able to switch between INPUT and OUTPUT as fast as it is required for "1-wire". If I pull the data pin to low (with a resistor) just for testing, I see that the input (data pin) seem to react to changes of the physical world. (The "1-wire" libary "SimpleDHT" shows different error codes.) with best regards, Ford. ------------------------------------------------------------------------------------------ |
