HopeRF RFM22B transceiver (868MHz legal in Europe)

Started this discussion. Last reply by Martint BuildYourOwnDrone.co.uk Jan 1. 3 Replies

Hi all, I'm wiling to write the Arduino code required to replace the expensive and illegal (in Europe) 900MHz XBee  telemetry modules with the un-expensive and legal HopeRF RFM22B modules. But for…Continue

"you do know that the ArduPlane code supports it, right ? All you need to do is to configure one of the auxiliary channels (5, 6 or 7) to have the flaperon function. The wiki explains a bit better how to do it using the APM planner GUI"

"Hi there Greg, Yes, I'm still working on the camera stuff, but not as mutch as I would like. The most recent version of the code is in the APM_Camera git branch. It contains libraries to control the mount (AP_mount) and the camera…"

"Hello Cory, I don't know if you have looked at the 868 MHz band in detail but there is an issue with using that here in the UK & EU, there is a limit to the time they can operate, it's known as the "Duty cycle", another…"

"Amilcar, How is this going? Any progress on Arduino code? I'm working on a Arduino based RF module that uses the RFM22B (433, 868 or 915) http://blog.ckdevices.com/?p=119 There are lots of possibilities for this module, but one use would be to…"

Amilcar Lucas commented on Michael Oborne's blog post New! APM Planner 1.0
"Martin, Jim We have some experimental code where you trigger the camera via a mavlink message from the GCS mission planner, or via a mission command. It supports both servo, relay, or a camera electronic trigger signal.   But the code is still…"

Amilcar Lucas commented on Adam Rivera's blog post Object Tracking - Proof of Concept
"This is pretty cool. We now have a method to control a model mounted camera via MavLink. So your code can control the camera movements on the model.   Good luck with the implementation. It's you PhD. work right ?  "

Amilcar Lucas commented on Owen Booth's blog post Sonar mount on Pan/Tilt mechanism?
"I'm pretty sure you can do this with the AP_Mount code in the APM_Camera branch.   Most probably without changing a single line of code.  "

"Davey the code fits fine in the 1280, you just need to disable cli.   Doug, did you take a look at my patch a3f75347295a in the APM_Camera branch ? I think it fixes some cases where the flaps are configured as channel 8.  "

"Hi,   Nice work. I wanted to use the RFM22 modules a while ago, I even bought a couple of them, but I did not use them yet.   I took a quick look at your files and have some questions: 1. Why not move the common rfm22.pde file to a library…"

About Me:
An Electrical Engineer who majored in control and robotics.
Worked with FPGAs for the past 10 years.

Professionally designs and programs real-time embedded systems for high resolution image processing and automotive applications.
Tell us a bit about your UAV interest
I like slow fliers, and as much hightech as possible.
I'm working on improving the camera mount code to provide tracking and stabilization.
Later on I might even try to do some image processing, the FPGAs are getting cheaper day by day. Optical target tracking anyone ? ;)

I installed Eclipse IDE for C/C++ Developers on Mac OSX 10.58.

I want to setup for Arduino IDE and svn use on Google, I use terminal commands to get current svn builds from DIYDrones but want to be able to create new repository for my changes and do quick compares to integrate new designs as the appear on DIYDrones. I loose to much time manually going thru the code changes from all the contributors. I like to use X-Code to review code too. Thanks for any help or direction to a good source of online help. It is a lot to get these sw tools working together, but will be much better for fast development and trouble shooting. Cheers
