How to use the MPU6050 Accelerometer Gyro Temperature robot skill
The MPU6050 EZ-Bit module is an all-in-one Gyro/Accelerometer/Temperature sensor over an i2c connection. This ARC control will read data from the sensor and set EZ-Script Variables, respectively. The control will require an Initialization (INIT) before the sensor will return data. If the sensor is not connected, the EZ-B v4 will lock up. This control will not read data automatically. We have provided a ControlCommand() for querying the device and setting the variables. Each time you wish to receive data from the MPU6050, you must ask the control to RUN ONCE with ControlCommand().Here is an example code for looping every 100 milliseconds to request data from the MPU6050. The data from the MPU6050 will be stored in EZ-Script Variables. You may press the CONFIG button on the control to see what variables are being set with data. Ensure you have an MPU6050 ARC control added and an MPU6050 connected to the i2c of the EZ-B, and paste this code into an EZ-Script control. When this script runs, the MPU6050 will continually update the specified variables with data every 100ms... Check the Variable Watcher to view the data from the sensor.
ControlCommand("MPU6050", Init)
:loop
ControlCommand("MPU6050", RunOnce)
sleep(100)
goto(loop)
In this video below, I am using the JD project with MPU. The project can be found on the EZ-Cloud as JD With MPU6050 Accelerometer.

Can anyone at Synthiam in the development team provide the details about the MPU6050 class being used in this service? Are these values YAWPITCHROLL or QUATERNION or EULER or REALACCEL or WORLDACCEL?
You’re looking at the code that you pasted. There is no class. That is the class. It reads the values and assigns them to variables as you can see.
it appears from reading the code that there is 14 bytes read and they’re split into different variables that have names which explain what they are.
Thanks, DJ sorry for the stupid question. This is just bringing back raw data from the MPU6050.
