Compile Error

Hey Ther

I have a problem compiling my sketch…
I get this error:
exit status 1
Error compiling for board Arduino/Genuino Uno.

What dos that mean?

My code looks like this:

Cayenne Ethernet Example

This sketch connects to the Cayenne server using an Arduino Ethernet Shield W5100
and runs the main communication loop.

The Cayenne Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.


  1. Set the token variable to match the Arduino token from the Dashboard.
  2. Compile and upload this sketch.

For Cayenne Dashboard widgets using digital or analog pins this sketch will automatically
send data on those pins to the Cayenne server. If the widgets use Virtual Pins, data
should be sent to those pins using virtualWrites. Examples for sending and receiving
Virtual Pin data are under the Basics folder.

//#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
#include <CayenneEthernet.h>
#define virtuel_co2 V0 //set output to Virtuel Pin V0

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token = “------------”;

void setup()
int co2in = analogRead(A0); // declare input
float virtuel_co2 = co2in * (2000.0 / 1023.0); //Calculation




void loop()


Is that the only error, or is there more above it?

What version of the IDE and what version of Windows and was it installed through the Windows Store?
