Re: Streaming mjpg from Raspberry Cam

Liam, Good work and thank you for making input_raspicam available. I'm currently running it on my RoombaPi robot and I am getting about 8.5 FPS. I am not seeing the picture go dark over time as others have reported. I am running up to date raspbian on a Rev b Version 2 with the camera mounted upside...

Re: Using raspivid with mjpg-streamer

That's what I ended up doing as an interim solution. I can only get about 10FPS to work in a some what reliable fashion. I'm hoping the someone will add a http server option to raspivid or a raspivid type plug-in for mjpg-streamer. Using the mjpg-streamer http server as an example, I figure that I w...

Using raspivid with mjpg-streamer

Any ideas as to how I can use raspivid with mjpg-streamer or something similar to stream video from webpage. I am also using WebIOPi if there is anything in there that would be helpful. Here's the typical html that I use to display the video stream from the RPi using mjpg-streamer and a attached USB...

Re: Driving multiple servos from the RaspberryPi

@ame, I added the change that you requested to handle larger count values based on the number of servos specified. The new limit is (cycle_ticks / num_servos - 1) although values > ~300 will not be useful and may damage your servos. I have not yet had a chance to test the changes so let me know if t...

Re: Driving multiple servos from the RaspberryPi

@rgh, Thanks for sharing the ServoBlaster source. I'm using ServoBlaster, the IPGamePad Android application and a UDP server application that I wrote to control a small servo driven robot that I demoed for the Michigan Robot Club . I did create my own fork of ServoBlaster and added a parameter to sp...

Re: Driving multiple servos from the RaspberryPi

by joan » Tue Oct 23, 2012 9:02 am I have continued my experiments with PWM for motors/leds and servos. I found memory <> memory DMA unreliable (memory <> peripheral memory seems fine) so abandoned that as a way of triggering servo pulses. Currently I'm triggering the servo pulses using a timer tic...

Re: Why am I missing about 90MB? / Stripping unneeded things

By default a certain percent of the file system blocks are reserved for root so that root can still logon and do cleanup or such should the system run out of space. You can use sudo tune2fs /dev/mmcblk0p2 -1 to see how many blocks are being reserved. And use sudo tune2fs /dev/mmcblk0p2 -r0 to free t...
