Re: gpio-keys and gpio-mouse driver source code

I'm looking to use this with AdvMAME on Raspbian. I have an old C64 era joystick hooked up to the GPIO, and everything is checking out OK on the hardware side (using the WiringPi gpio command line utilities). Where should I start on the software side - I can't find bcm2708.c anywhere on the filesys...

Re: fswebcam stops working

I'm connecting to my pi via ssh -X this enables X11 forwarding, so guvcview runs from the pi through my ssh session on my main pc, this should at least allow you to try different framerates. I think that basically, higher resolutions (or changing from the default that the camera starts in) make the ...

try guvcciew, I found that I could start my webcam (philips SPC900NC) @ 160x120 resolution, any change of resolution would cause the timeout issues.

Not sure if that's the same patch? As it's from 6th July and gordons post on here mentions his fixes on 21st that haven't been pushed yet.

I get this error with fswebcam but instantly, it just does not capture any frames at all.

Re: How can I change back to Openbox window manager?

Also, if you set raspi-config so that you boot straight into X, you can then logout of openbox (exit I think), from the login prompt you can also choose your window manager session from there, log back in and everything will be as you want it.

Re: OpenGL?

The pi uses open gl ES (2 I Think), which is not the same as openGL, your mileage will vary, apparently stellarium does work, or at least it did, maybe jamesh can tell us how he got it installed?

I also have this error using a phlips spc900nc camera, I get lots of usb resets when I use the camera, my hub is pretty solid with it's own 2amp psu, 2amp solid 5v psu for the pi, it does attempt to capture a frame using fswebcam but it times out.

Re: Safe Mode

What happens to that pin once the pi has booted? Does it then become available for GPIO or is it permanently used for safe mode? Just thinking you would want to be fairly careful what you had connected to that pin, especially if you're using i2c devices.

Re: Frustrating problem once the pi has moved between displa

I suspect that the ethernet may not have a great deal to do with it, it's possible that the TV is pulling power in some way, try a different power supply if you can. Did you also check the current rating on your keyboard? It might be printed on a label on the base, if it's greater than 100ma then th...

try the keyboard in a powered usb hub? Make sure that measuring between tp1/tp2 is reading >4.75v. Does the network come up? do you see the 3 right-hand leds lights come on?

can you still do longer exposures with that camera james? I know that you said before that you'd managed to get a reasonably long exposure out of it (compared to the 'normal' framerates?).

Re: [BareMetal] USB

You could use one of the teensy boards or a v-usb solution to convert ps2 keyboards/mouse to serial. You can also use gpio-keys as a keyboard driver and gpio-mouse as a mouse driver but for a decent keyboard matrix you'd probably need a shift register or 2. see here for gpio-mouse/gpio-keys informat...

Re: Model B with 128MB of memory?

It's easy to see whether you've got the correct ram chip, check the part number that is printed on top of the chip. It should read K4P2G324ED-AGC1, the relevant part of that part code is the '2G' this a 256MB chip (2Gbit/8= 256MB).

I also wonder whether this can be extended to a single/dual trace scope of some sort? I've seen circuits on diy boards that use an ADC connected to 8/16 digital pins, which are then read and converted. Probably a bit of a simplification but from memory it's not far off that.
