I’m happy to finally publish a first working version of the FreeIMU Magnetometer and Accelerometer Calibration GUI. Currently, it should allow you to visually calibrate your accelerometer and magnetometer after you connected your IMU to a microcontroller running the FreeIMU_serial example in the FreeIMU library. NOTE: You have to use the FreeIMU_library available on the repository, not the

Testing the FreeIMU framework orientation sensing after using the new FreeIMU calibration GUI to calibrate Accelerometer and Magnetometer. As you should see, this is pretty accurate and drift free estimation.

I’m happy to inform you that I’ve finally created a community website for the FreeIMU project. You can see it at freeimu.varesano.net. Right now, it’s a simple forum website built on top of Drupal with still a pretty crude graphic.. I decided to use Drupal instead of other forum specific platforms (SMF, phpBB, vBulletin, etc..) because

Here it is, the new MS5611-01BA03, finally on my table for testing. 🙂

Just a dumb video testing digital input/output on buttons in my CC430 based project.. nothing fancy but needed testing. See the SPI LCD connector and the MPU6050 over I2C.. these will be fun! Here is the code: #include <cc430x613x.h> #include <inttypes.h> int main(void) { unsigned int count; uint8_t but0, but1; WDTCTL = WDTPW + WDTHOLD;

This is a presentation video I recorded some time ago which presents the FreeIMU project as of Autumn 2012. Hope you like it!

This is Wired Italia documentary Arduino: Creation is Child’s Play. I’m interviewed around minute 9:50 and I talk about my FreeIMU project and I fly my quadcopter. Thanks to Wired Italia, Arduino and Opificio Ciclope for the opportunity.

Simple tests on the LS013B4DN04 (3.3v version of the 96×96 Sharp Memory LCD with Flat Cable connection) using a custom made breakout board I designed etched by my friend Franco Magni. This uses this Arduino Library: http://code.google.com/p/arduino-sharp-memory-lcd-gfx-library/

I’m happy to finally publish the code for drawing nice 3D scatter plots of the incoming accelerometer and magnetometer data for the Ellipsoid into Sphere calibration available in the FreeIMU GUI. This will be soon released in upcoming v0.3 of the FreeIMU GUI but for now is available only on the repository. This will allow
