"I like this project a lot, I'm a huge fan of STM32. I think the real question here is programming language not IDE. Java based or portable C code. If you use Java based it limits functionality as these don't support DMA and multitasking which will…"
"Hi Sergey,
I've gotten your messages, I've not ignored you. My new job has halted progress on my projects, but I would love to share some information to help you out. I will reply via email this weekend at some point with more info. Thanks for being…"
"Are these sensor designs open source as with everything else? I would be interested to see the schematic of how they are designed. You say we can make our own, and provide a link to digikey, I would like to see the schematics if all possible. Also,…"
"See my implementation of a BLDC RPM sensor here: BLDC Hall Effect Sensor. The sensor simply uses at least one magnet (I use 4 to get higher update rate) and a hall switch (about $.40 on digikey).
"200 Hertz for 9 degrees of freedom + filtering + DCM / Quaternion calculations is more than sufficient for anything I can think of, since the data is already filtered you need to take that into account.
"I believe the documentation / protocol you point to is over the wireless bluetooth (I don't see anything related to I2C adresses / registers and motionplus), has there been anything done towards listening on the I2C, and getting the data straight…"
"Hmm... Apparently I2C / SPI can read analog voltages since the accelerometers don't seem to be connected to ADC's like the external gyros in their block diagram."
"I think you could definitely clean the pressure data up a lot using a moving average filter, thanks for pointing out the BMP085 to me, looks like a good simple cheap sensor.
IDG500 is showing about .8 deg/sec RMS drift rate from what I see,…"
