Hi,
I've been experimenting using the MPU9250 on a number of development boards, for example the arduino's and the Particle Photon. I've been able to get the MPU9250 working and get the raw data off.
One of the key features of the MPU9250 is that it is able to use Fusion techniques on board to take the processing tasks off of the processor, but to configure them I need to use the Motion Studio softwear to define my required required outputs, create my firmware and upload it to the 9250. Now I know that it not possible to do with the lower end arduinos, and possibly the Photon. So I will have to expand my horizons atleast to create the firmware.
My question is once I have configured my 9250, will it loose its firmware on each power cycle?
I know I can save on to the 9250 some calibration values, but if it retains it firmware as well, then I can configure the 9250 on one platform but still use in in my intended builds, which for other design reasons have already been set.
Whilst I've been reading around the issue of using the motion driver tools, an answer to this question will save a tonne of development time.
Thanks
Liam
