It's been a while since the announcement of the first FreeIMU v0.4 prototype built and you may be asking what I've been doing with it..
Well, the tests I've been doing so far with my v0.4 prototypes have been completely successful.. the unit works great. Unfortunately, I've been able to only test the 6 axis (gyro & acc) sensor fusion of the DMP in the MPU6050. As far as I know, Invensense only released software examples for that and documentation and code for a complete 9 axis DMP sensor fusion is still not available. So, I haven't been able to test the accelerometer, magnetometer and gyro on DMP sensor fusion. Please, if you happen to have more documentation or code for this please let me know!
My original plan was to build other v0.4 prototype boards and send them to various developers working on this kind of application so that, by sharing efforts, we would be able to provide good software for the new sensors.
Unfortunately, me and Jussi have had a lot of troubles with our suppliers. Both the MS5611 and MPU6050 have been almost unfindable for about 3 months while we had a lot of troubles with the HMC5883L that ACAL sent us. It seems that at ACAL they don't know how to properly store/ship moisture sensitive devices as we had many issues with them: they once even shipped them unsealed!
This kind of troubles really slowed down my progresses of building some prototype boards for developers, that's why the v0.4 testing didn't progressed much in the past month.
Fortunately, it looks like we are again on track again with the prototype boards and I hope to have them ready before Christmas. I'll announce later this or next week the availability of FreeIMU v0.4 prototypes for developers.
Meanwhile, we are also starting organizing the production run of the boards. I'm already in contact with local SMD assembling factories so we are now in the process of sourcing all the components and finalizing the designs so that we can start the production.
This is actually the first time I deal with organizing a factory made production run of a board, yes last time they were all hand made by me, so this is really an interesting experience and I'm really learning a lot.
I'll leave you with a picture of all the components I just received. As you can see, these are reels of components: hundreds of caps, resistors and sensors! Great!
I'll keep you posted on the production progresses.
