Re: CommodorePi Problem

- 99% of the people here will not know what CommodorePi is, its polite to not force us to google for it. You will probably get more help from the developer of CommodorePi, but since there has been no updates for over year that might not be easy either. If you think you have a hardware problem then ...

CommodorePi Problem

I have this on a SD and hooked it into my Pi model B the question is: How do I get it to work? or do I just keep waiting? I waited for about 5 minutes but it didn't work all it had was a blue screen that had text flash and move down the screen too fast for me to get a good look at it... as well as w...

I need to mount a flash drive or have some way of getting the flash drive be the main thing I save to without having to go through menus or the file system. All I need to do is make the pi boot from the SD and save to the USB flash drive

Re: Raspberry Pi, GPIO, and other CPUs

I guess the PI could be used as the "Graphics output device" for a far more powerful ARM based system, as in fact the PI is mostly a GPU with a small CPU tacked on, but its USB "pipeline" may become a bottleneck, I doubt its fast enough to transfer live vide signals through it. Then again you could...

Re: Raspberry Pi, GPIO, and other CPUs

Almost an impossible proposition! The only "High speed" connection the PI has is USB (and through USB Ethernet). None of the PI's GPIO interfaces really provides enough throughput to provide fast enough data interchange with another CPU to create a workable DUAL-CPU system. The SPI interface is the...

Re: Raspberry Pi, GPIO, and other CPUs

Hi, control another processor to give the Pi more processing power. A solution that comes to my mind is to use several RasPis networked together (Ethernet). Various boards with some processors (microcontrollers) could be attached to GPIO, but generally speaking, this hardware doesn't have significa...

Raspberry Pi, GPIO, and other CPUs

I need to know if the pi can hook to an GPIO expansion board and then to some sort of circuit to control another processor to give the Pi more processing power. Also would like to know if there are more single board PCs that could accomplish this feat.

Is this for saving to the hard drive and booting from the SD? That is what I would like to do, I could have more memory and be able to use the SD only for booting.

If not, you might be able to hack it and run the whole lot from 5V.
I have no idea if it is regulated down the board or not

Powering a 7" 9v LCD display from 5v

I want to power a lcd for a project but I want the battery to power both the pi and the display I have rca input and it runs on 9v to 12v at one amp. Is there anything I can use to boost the voltage and amperage?
