Re: Need API support to provide micro seconds delay

Hi. Did you manage to get it work? In Nodemcu for esp32 (currently in development stage) they implement OneWire interface for esp32 using RMT. I plan to use it for DS18B20 since I don't like the idea of using delays for communication protocols. NodeMCU OneWire implementation for esp32 - https://gith...
