We use a software line with success. The soft serial library contained with the Arduino IDE is severely lacking, but Mikal Harts Soft Serial library (http://arduiniana.org/) is much more functional (although it shares a timer used to control servos,…
I forgot to mention. When we use the software serial line to communicate we do get jitters in our servos. I imagine this is because the timers normally used for holding the servos are being "borrowed" to operate the software line, but I am no expert…
Very nice work. I think a project to build an open source ground station similar to the paparazzi one would be nice. Any move on trying to fly the aircraft via a serial uplink. I wonder whether a process that basically updates the target way point v…
That is so cool!
We use a soft serial line to communicate through an Xbee (our GPS talks at 1 Hz and our groundstation talks to our AC at around 12 Hz, so it should work) to our GS. The SoftSerial that comes with the Arduino IDE is severely lacking in functionality…
So I could be wrong, but I do not think you should think of the differential pressure sensor as a pitiot tube. A pitot tube takes the static and pressure from the same air flow, but with the shield one pressure is read from the flow while the other…
I like this system. We implimented two way also, and we didnt go with a second Arduino because of cost (we are trying to build a swarm), but this opens up ports and you get to leave your I2C line open
I would be happy to share the source code for the ArduPilot and documentation on the changes made and the comm protocol but not the groundstation.
Care to share the project source code? I'd be interested in studying the graphics portion of this.
Visual Studio C++ with a QT add on for graphics
What language was the ground station software written in?
well done!! as SgtRic said, one if difficult enough so two is quite something.
Amazing work people!
I have enough trouble working with one aircraft... I never imagined trying to keep multiple in the air!
A couple of people at the University I attend and I had our first flight the other day, and we wanted to tell all of you about it.
I will start with the goals of our "team". Our goal is to create a network of UAVs that allow for mulitple users and/…
Rather than using the same serial line for GPS and telem, what we did, was simply add a software serial line to pins 8 and 11. This allows us to communicated at about 12 Hz with filtering and all that fun stuff.We have tested this system, actually c…

Our very first flight (with two way telemetry)
A couple of people at the University I attend and I had our first flight the other day, and we wanted to tell all of you about it.
I will start with the goals of our "team". Our goal is to create a network of UAVs that allow for mulitple users and/or multiple ground stations attempting to control multiple vehicles. We felt that the ArduPilot platform was perfect because we have access to source code, it is inexpensive and a vibrant community which could, hopefully, provide feedback.
We were ab… Continue
