OneWireNoResistor
A slight update of the popular Arduino 1-wire library for AVR-based arduinos that...
-
Eliminates the need for the extra pull-up resistor (the big show)
-
Adds a busFail() function to let you test for a shorted bus
-
Slight updates to comments and formating
New branch is for the ESP8266 and was contributed by Antoine here..
