Mindsensors AbsoluteIMU-ACG

[Stone]

Hi,
I was wondering if someone has interest in implementing the mindsensors AbsoluteIMU-ACG in the lejos API.
Because I wan't to buy that sensor from mindsensors but I haven't yet the knowledge to make my own classes for using this sensor.

I'm interested in this too. I might take a shot at implementing this myself if I don't hear anything.

Send me the sensor and I will write a driver for it.

Best,

Rudolf Lapie started writing a driver last October. But I haven't heard from him since. I contacted him.

Actually, parts of this seem to be done already. If you look in the API, there is a CompassMindSensor and AccelMindSensor:

At first glance, I believe these will work with the ACG model. The only thing I can't seem to find is a Gyro implementation. So creating a full driver under one class should be easy, as you could simply use the code from the above two classes, and then implement the Gyro side of things. There is code in NXC for it as well that could be used as a reference while you do it in Java.

I just ordered my AbsoluteIMU-ACG yesterday and plan on doing just that once it arrives. I'll let you know how it goes.

Hello,

I started developing a driver for the Absolute IMU and a test program to check its function.

Usage : The driver has 4 inner classes (one for each sensor : accelerometer, tilt sensor, gyroscope and compass). Simply create those that your model supports to start reading its values. The testprogram shows all values from the 4 sub-sensors. It shows the actual values on the screen of the brick and shows a chart on the PC for historic data. Before starting you will need to setup a bluetooth connection on the PC to your brick. Then run the program on the brick, start 'nxjchartinglogger.bat' (in the bin subfolder of the LEJOS program) and connect to your brick from nxjchartinglogger. This should start showing 10 lines with the data. Now shake your IMU and the charts should go bezerk.

Let me know if you have any issues with it or made enhancements to the driver.

Kind regards,
BlueHaze.
