Widget ADXL345

Hi, which widget could i use for my adxl345.
It is working on the Arduino Plotter but I dont find the right widget.

You’d need to build up the [x,y,z] string

Cayenne.virtualWrite(12, [x,y,z], "accel", "g");

you mean in this position? Which Widget should i use?

//Default function for processing actuator commands from the Cayenne Dashboard.
//You can also use functions for specific channels, e.g CAYENNE_IN(1) for channel 1 commands.
CAYENNE_OUT(1)
{
//Cayenne.virtualWrite(1, millis());
Cayenne.virtualWrite(12, [x,y,z], “accel”, “g”);
}

 CAYENNE_OUT12)
 {
 Cayenne.virtualWrite(12, [x,y,z], “accel”, “g”);
 }

it will auto create the widget.

do you have the complete code? Because now with this change I get:
xwas not declared in this scope

Here my code:

Store the acceleration value in the variable x, y, z and create the sting.

    float x;
    float y;
    float z;

  buffer[0] = '[';
  size_t offset = 1;
  dtostrf(x, 1, 3, &buffer[offset]);
  offset += strlen(&buffer[offset]);
  buffer[offset++] = ',';
  dtostrf(y, 1, 3, &buffer[offset]);
  offset += strlen(&buffer[offset]);
  buffer[offset++] = ',';
  dtostrf(z, 1, 3, &buffer[offset]);
  offset += strlen(&buffer[offset]);
  buffer[offset++] = ']';
  buffer[offset] = 0;
  Serial.println(buffer);

Cayenne.virtualWrite(12, buffer, “accel”, “g”);

Hi, I get some complex with your code.
How could I link this 3 codes in one function? See the picture attached, there are the 3 values in the Dashboard but i need in one graph15

Cayenne.virtualWrite(1, event.acceleration.x);
Cayenne.virtualWrite(2, event.acceleration.y);
Cayenne.virtualWrite(3, event.acceleration.z);

the above code which i gave does the thing. it creates a single widget with all three values.

This is the last part of the code with your support but i become some error codes. Sure i have to delete some codes but i´m not sure

//Cayenne.virtualWrite(1, event.acceleration.x);
//Cayenne.virtualWrite(2, event.acceleration.y);
//Cayenne.virtualWrite(3, event.acceleration.z);

}
}
//Default function for processing actuator commands from the Cayenne Dashboard.
//You can also use functions for specific channels, e.g CAYENNE_IN(1) for channel 1 commands.
CAYENNE_OUT(12)
{

buffer[0] = ‘[’;
size_t offset = 1;
dtostrf(x, 1, 3, &buffer[offset]);
offset += strlen(&buffer[offset]);
buffer[offset++] = ‘,’;
dtostrf(y, 1, 3, &buffer[offset]);
offset += strlen(&buffer[offset]);
buffer[offset++] = ‘,’;
dtostrf(z, 1, 3, &buffer[offset]);
offset += strlen(&buffer[offset]);
buffer[offset++] = ‘]’;
buffer[offset] = 0;
Serial.println(buffer);

//Cayenne.virtualWrite(1, millis());
Cayenne.virtualWrite(12, buffer, “accel”, “g”);

}

CAYENNE_IN(12)
{
CAYENNE_LOG(“CAYENNE_IN_DEFAULT(%u) - %s, %s”, request.channel, getValue.getId(), getValue.asString());
//Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError(“Error message”);
}

you can delete the entire CAYENNE_IN(12) function

Do it, but i get the error: stray \342in program, see picture

you can delete the entire CAYENNE_IN(12) function

Hi, i have delete the entire CAYENNE_IN(12) function as you can see in the picture above without result. I get the fault stray \342 in program

delete the (double quotes)" from "accel" and"g" and retype them.
