Re: Status update

Typos and divorce papers notwithstanding, that's some serious boardwork.
Take your time and do it right. We all appreciate the work you guys (and gals) are putting int this!

Re: Camera module! (And a picture of JamesH)

One thing I have noticed about folks here, if something isn't available, they go buy something that they think looks right, then try to get someone to help them get it working. This is your basic Do-It-Yourself mentality, and I think it is perfectly reasonable. Many good devices have come out of the...

Re: Maximum numbers of USB ports

The USB standard allows for 127 devices. If I had to guess, I'd say you are having trouble seeing the hubs beyond the first because the root hub can't see the third tier hub controllers through the second tier hub controller. Whether this is a problem with tier two hub, or natural behavior based on ...

Re: Default display parameters for DSI

Welp, I'm reading up on the forums, having just joined last week, so I may not be completely current, but I'll give it a go. I'll assume that the DSI/CSI interfaces were designed in because the SoC has the pins for them (according to http://www.designspark.com/files/ds/supporting_materials/Broadcom%...

Re: Touchscreens for Raspberry Pi

One possible solution (god love the people at AdaFruit): http://www.adafruit.com/products/335 They say up front that it is designed for an Arduino, but they wrote an open-source library that should be "easily adaptable." If you don't mind the smaller display area, this would be a good starting spot ...

Re: Roadstar LCD5014 5" TFT. Conversion from 4 pole 3.5mm.

Your 4-pole to RCA will work because it is just a connector conversion. Still an analog signal over three wires (the 4th is the ground). However, your RCA to HDMI should only convery RCA into an HDMI signal, not convert HDMI into RCA. (Most signal converters only work one way.) What you can do is ta...

Re: How to Turn Off Monitor/backlight (not black screen)

Excellent. I may still see about the GPIO solution once my RPi comes in, but having a working solution in hand is always good.

Re: Arduino compatible on the Raspberry Pi: AlaMode!

Wow... I had been speculating about strapping an Arduino to the Pi, so that I could use one of the touch shields. (spec.: http://www.makershed.com/2_8_TFT_Touch_ ... mkad36.htm)

can't wait to see what people come up with for this.

Re: RasPi Beagletouch equivalent

Sweet looking unit. Well, here's your pinouts for the BeagleTouch: http://elinux.org/BeagleBoardPinMux#Liquidware_BeagleTouch Wire up an adapter cable to get from the Pi's GPIO to the display. I'd recommend using outboard power, though. With video, backlight and an audio amp, it must suck up some ju...

Re: 7" monitor cabling conundrum

Twist the shielding into a wire, then solder a pigtail from that to a ground.
If you leave it hanging, it wont hurt anything, but you lose the shielding properties.

Re: How to Turn Off Monitor/backlight (not black screen)

Q: How is your backlight getting power? My thoughts: Set a timer running in the background (might have to add an RTC module, I think the Pi doesn't have one). At the 'Turn On' time, drive one of the GPIO pins high. That pin gets tied either to the backlight pin of the display (it the display can use...

Re: Touchscreens for Raspberry Pi

I've looked at those alibaba screens. THey look sweet, but the $20 - 200 per piece is just two weird for me. I'm looking at another possible solution that would open up the possibilities. Buy whatever TFT LCD (or LED, oLED, etc.) you like, then buy the touch panel separately (it's just a resistive f...

Re: dual screen

I remember good old X Windows. No clue what the current LINUX version is (MickeySoft has Mouse Without Borders). Theoretically speaking, any USB display adapter that is supported by LINUX (preferrablly Debian) would work as a secondary screen. Mind you, I'm speaking hypothetical, and can't it would ...
