Re: LLVM build options

Hi there,

Did you succeed in buiding llvm 3.2 with REQIRES_RTTI=1 ?
I am having troubles, actually `make test` fails.
I would like to test the "numba" JIT compiler on my raspberry,
so using the deb from testing repository will not work,
because RTTI is disabled :cry:

Re: Video4Linux2 driver ready!

Thanks a lot RpiName! as you suggested, getting only 64 x 64 tiles from the captured frame in python opencv was related to the version of opencv in the repositories. I compiled version 2.4.5 of opencv , and tada! everything runs nicely ! This is realy a milestone for my computer vision project on th...

Re: Video4Linux2 driver ready!

Thank you for developing this driver. I'm afraid it still does not work for me in python opencv : the driver only returns 64 x 64 pixel tiles of the captured frame. I tried this in ipython, using opencv 2.3 and the newest uv4l and uv4l-raspicam: In [1]: !uv4l --driver raspicam --auto-video_nr --enco...

Re: Simplecv + Camera board guide

Many thanks for this guide. Very useful. Unfortunately I am still having a problem with a small image (64x64) in SimpleCV. I have added the LD_PRELOAD variable to .bashrc but this did not solve the problem. Could you list the sequences of commands you run when starting up SimpleCV? (I have installe...

Re: Driving multiple servos from the RaspberryPi

Could you connect a local USB keyboard and a monitor/tv and see if you still get the issue? There is nothing in the driver that should pause for 30 seconds, so I wonder if the effect you are seeing is actually down to lost packets and retries on your network connection. thank you for your reply , b...

Re: Driving multiple servos from the RaspberryPi

Thak you for this usefull piece of code. :D I successfully compiled the module after modifying the source to only adress GPIO 23 and 24. All works fine, but sometimes the echo command hangs for about half a minute before execution. Someone has an idea whats the reason for this issue? As i would like...
