Hi,
I'm new to the forum. I've been working with Uno and nano for a little while, but just got a NodeMCU (ESP-12E) and am programming it with the Arduino IDE.
The module reads analogue data and sends it to thingspeak without problem. However when I try and add a DS18B20 onewire sensor to a digital pin I get an error I don't understand when compiling.
The error is:
In file included from C:\Users\Al\OneDrive\Arduino\ESP8266_DS18B20_temperature_sensor_REST\ESP8266_DS18B20_temperature_sensor_REST.ino:16:0:
C:\Program Files (x86)\Arduino\libraries\OneWire/OneWire.h:108:2: error: #error "Please define I/O register types here"
#error "Please define I/O register types here"
I got this code from the web and have stripped out all the wireless lines to try and isolate the problem. My code should now only print to screen.
Can anyone help please.
Thanks

oldTemp = -1;
}
void loop() {
float temp;
do {
DS18B20.requestTemperatures();
temp = DS18B20.getTempCByIndex(0);
Serial.print("Temperature: ");
Serial.println(temp);
} while (temp == 85.0 || temp == (-127.0));
if (temp != oldTemp)
{
oldTemp = temp;
}
delay(1000);
