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:

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 graph
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
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.
