I had a hard time finding the repo, but I finally did it. To save others the trouble, here is how you clone it: git clone git://git.openpilot.org/OpenPilot.git --branch brian/crazyflie After that you can build it like this: make crazyflie I haven't gotten around to actually flashing it, but I'll pos...

Hi, I'm trying to port the arming function over from OpenPilot, but I ran into a problem: The arming process requires the controller to be helt at a certain position for a certain amount of time. Whenever the stick leaves "the arming corner" the arming process is reset. While I was scratch...

how easy/hard would it be to port this code to the Crazyradio? Frankly, I have no idea, as I haven't really looked at neither, chip nor code. It shouldn't be too hard, though, after all the CR is able to run the nRF communication and a PPM decoder at the same time (although I've never managed to ma...

Hello! I've tested your code. Hover parameter is setting correctly. But when I set it, crazyflie goes crazy (jumping). How to control crazyflie in hover mode? Which range are valid for setpoint.thrust ? Maybe this behavior has something to do with the fact that on a RC remote the throttle stick doe...

Hehe.. first bragging about it and then forgetting to push the changes to github.
It's all there now.

Cheers.

Great work ali! This is something we have wanted to do for a long time but never got the chance to. Great to see that someone else did! Funny thing I found this http://www.airspayce.com/mikem/arduino/NRF24/crazyflie_client_8ino-example.html only hours after I got mine working. ;) And it's from 2012...

Wow! Great! How about alt hold mode? I think I've got it. Now PPM channels are assigned as follows: 1: Yaw (Rudder) 2: Pitch (Elevator) 3: Thrust (Throttle) 4: Roll (Aileron) 5: Arm/Disarm (simply realized by setting setpoint.thrust=0 if PPM input is < 50%) 6: Hover/AltHold (if PPM input > 50% flig...

I guess it could be done by assigning switches on the remote to spare PPM channels and having the module firmware send custom commands like alt-hold or arm/disarm.

I'll look into it.

Hi, I've written a little AVR program to control the Crazyflie without a PC or even the Crazyradio. All you need is a RC transmitter with trainer port or TX module slot that will put out a PPM signal, an AVR (almost any kind of AVR based Arduino will do, I developed this on an Arduino UNO), and a nR...

Hi, it's been almost a year, so I thought I'd ask if there was any progress on this subject. I've found a few resources on the web where people are building their own modules for the popular 9x tx and others (see http://www.rcgroups.com/forums/showthread.php?t=1564343 or http://forums.openpilot.org/...
