<![CDATA[M5stack and DS18B20]]>I wanted to measure temperatures with DS18B20 and M5stack using OneWire. Which pin do I need to connect the DATA wire (yellow)?

you are more or less free in choosing a GPIO/pin as long as it hasn't been used internally and is available on the M5Stack bus or Groove port. The OneWire library should have a means to define the GPIO/pin to be used.

Check out M-BUS section on this page. GPIO2 or GPIO5 should be free to use.

Thanks
Felix
