I'm partial to the STM32 (ARM CORTEX-M3 based uController) line of uControllers, not only for their hardware mul/div instructions, but also for their ability to have the ADC converter continually scanning and pushing to memory its conversion results from a series of analog devices.
Some more progress on the GCS. I integrated a line builder and line manager. The line builder contains the editor to edit GPS coordinates of the line, as well as options for line thickness and color. The line manager imports these coordinates as a set, and given a name. This clears up the line builder, allowing multiple lines to co-exist.
The Line builder can import a list of GPS coordinates from a text file with the format: lat lon
For a class project, we built a quadrotor using the Sparkfun Razor IMU and a Atmega32U4 running the PID controls. After about a month of work, we successfully flew it with great results (alright, it wasn't super stable, but it stayed up!). Check it out at www.wyvernupenn.blogspot.com.…
I'm still working on the next installment on my SAGAR drone, however my progress has slowed, as I suddenly find myself in Boston for 7 weeks. Life can be very exciting when you work for the Department of Defense.
In the mean time, I have been asked by a few people over at SocietyofRobots.com on how SAGAR's micro-controller (an Axon) communicates with LabView. Instead of a bland answer, I spent s little time writting about the different problems hobbyist can run… Continue
