Yes, I do have projects in mind. One is the drone(s) that I
mentioned. Another is IMU and navigation in airplanes that I fly
in. Another is in road vehicles so I have a pretty cheap G-meter
:). The G-meter may wind up costing more but I have a whole lot
more fun programming and making it myself than I would opening a box
with a completed unit inside.<br>
<br>
By airframes, you mean you have several drones?<br>

<div bgcolor="#FFFFFF" text="#000000"> I just have to get by
the shop and solder in the pins before I can play with
them. I have 4 other IMU's to tinker with but this is the
first (too bad it had to be Bosch) that has the "sensor
fusion" already built-in. What Bosch did was include an
embedded uprocessor and developed their own code. I
cannot find out if they used Kalman filtering or not, or
exactly which algorithm they selected. I *greatly* enjoy
not having to write that code and optimize it for an
embedded box so if this works, I consider it money well
spent. However, Bosch does not have a great track record
in that respect. Plus, the more cpu load I can offload
from the BBB, the better I like it. :)<br>
I'm also using the Adafruit "ultimate gps" board (MTK
3339) for the same environment. Running tests now to
determine the lowest processor overhead involved with just
talking to the danged thing. Read() a char at a time, or
string at a time. Which method uses the least overhead?
And worse, getting a line at a time doesn't know when to
stop because the gps out uses Winblows CR/LF instead of
the UNIX/Linux '\n.' Using read() with fixed buffer size
is reading PAST the end of line into the next line because
of that. Grrr. Searching for problem resolution now.<br>
Minicom source has both methods in it's algorithm but I
can't determine which is used in their runtime. Their
output from the serial GPS strings looks correct but I
can't get my program to do that in canonical (get string
mode) to do that. Probably "programmer head space" error.<br>
<br>
This toy has applications in several areas, including
drones and etc.<br>
<br>
I want a drone so bad...<br>

<br>
Any comments about the device? They're a
bit less than $35 for a Teensy 3.1
compatible board. I plan to use them with a
Beaglebone Black. They are 3.3V units and
use I2C.<br>
