Here's a look at the latest iteration of my Parallax Propeller based quadrotor. The current implementation uses an ITG-3200 3-axis gyro as the only stabilization sensor.
The primary flight loop and PID code is written in SPIN. All the sensor, motor, and R/C interfacing is done in assembly. The code is available in this post:
I haven't decided if I'm going to keep it open or not, but I probably will. I'm mostly doing this for my own enjoyment. The Propeller is a great platform for this kind of thing. Not having to code interrupts makes a lot of things much simpler than they'd be otherwise.
Hey Jason, wonderful work! I am a newbie to quadrotors but a long time user of props. I have been curious to see an implementation using the propeller platform for a longtime. Do you plan on keeping the code base open?
Hi Jason - Well Done! As an early proponent of the Propeller platform, I'm glad to see it used for a Quad. My Propeller-asperations were shortened when the Arduino came marching along with its user base (which I also appreciate!). You are a far better programmer than I to create the entire implementation from scratch.
Did you use SPIN or assembler primarily? Are you open sourcing it?
