How to initiate mpu–6050 for this openframeworks program #1

Closed eighteight closed 10 years ago

eighteight commented 10 years ago

Please let me know what arduino sketch I am supposed to upload to mpu–6050/arduino in order for it work with CONV_MWAS. I am using this exact hardware setup: http://www.geekmomprojects.com/geekmomprojects-wp/wp-content/uploads/2013/03/DSC_1292.jpg (taken from http://www.geekmomprojects.com/gyroscopes-and-accelerometers-on-a-chip/ ). I have tried to upload provided MPU6050_DMP6.ino and MPU6050_raw.ino, but did not receive any sensible results in the app. Thanks.

Hello! I noticed at the link you provided that there is an Arduino & Processing sketch. Do those work with your device?

If everything's good on that end, then maybe try the latest Arduino library that we used: https://github.com/jrowberg/i2cdevlib/tree/master/Arduino/MPU6050

Hope this helps!

Yes, the sketches from that page work, and I am using latest from i2cdev. I am still not sure 1) whether I need to initialize arduino with an *.ino sketch for your openframeworks program to work 2) which arduino sketch is supposed to be used in 1)?

Thanks.

In hindsight I see how this is probably confusing. Unfortunately it's been close to a year since I've worked on this and sadly no longer have access to the hardware to check for you. My suggestion would be that if Arduino & Processing sketches are working, examine those... and just swap out the Processing sketch with my openFrameworks projects and make any necessary mods -OR- re-write the Processing sketch in openFrameworks and go from there.

Hope that helps!

For the record: The things started moving. Steps I had to add for this to work:

  1. Connect Interrupt output on MPU6050 to interrupt input of the Arduino (pin #2 on Arduino UNO).
  2. Upload MPU6050_DMP6.ino sketch provided to arduino.
  3. Run executable, wait for prompt, press any key. Voila!

Awesome! :-)

I'm going to close this issue. Glad to hear you're sorted.

Do you have any suggestion as to how to use MPU6050 for position acquisition (dead reckoning)?

Thanks.
