Hi all,
I try to use 2 UNO board + 2 nRF24L01 + DS18B20
I refer to the Tiny code.
Source:
I have installed the following libraries
DallasTemperature
mirf85
Narcoleptic
OneWire
RF24
SPI85
verify got error message:
digitalWrite(ONE_WIRE_GND, LOW); // set GND pin low

Hi,
Please post your code here;
Please use code tags.. See section 7 http://forum.arduino.cc/index.php/topic,148850.0.html
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf?
You can do all that on the forum without having to post it off site.
If posting is too big then attach it useing "Additional Options" tag.

ONE_WIRE_GND
is defined where?
got other errors
So? Fix the problems.
Do NOT post pictures of errors! Post the damned text.
You can't have both power(HIGH) and ground(GND) on the same pin.
#define ONE_WIRE_POWER 9
#define ONE_WIRE_GND 9
Why put it on a digital pin and not on one of the three GND pins or the one on the ICSP header?
You can't have both power(HIGH) and ground(GND) on the same pin.
Sure you can...he just did! Lesson learned: You can't put blue smoke back into the part that caused it.
