Function readData

samples/Temperature_DS1820/app/application.cpp:25–52

DS18S20 example, reading You can connect multiple sensors to a single port (At the moment 4 pcs - it depends on the definition in the library) Measuring time: 1.2 seconds * number of sensors The main difference with the previous version of the demo: - Do not use the Delay function () which is discouraged by the manufacturer of ESP8266 - We can read several sensors Usage: Call Init to setup pin eg.

//   You can recognize sensors by the ID or index.
