Pi and stdio.h vs. what?

Hi I can program in C, have ordered a Pi, and am looking at some possible software to write. a) Is there a nice library for graphical framebuffer/vector/3D and audio which is also available on Ubuntu 10+ ? As this allows me to develop without any extra tools. b) Is there a keyboard shortcut based mo...

Re: Farnell VS RS delivery times

Just ordered from RS, they say 4th December if ordered today. I don't mind waiting, and farnell do not do visa electron. I have had no problems with RS in the past, and expect them to deliver on schedule. Are both production runs for both suppliers made in the same place? Which supplier has the high...

Re: Language for Just Pi

The reading and writing can be abstracted by the machine. Just read and write as and when. The opening and closing is the trick. Try as create and exit auto commit.

Re: Language for Just Pi

The language if useful would be copied on to more than just pi. The question of usefulness would depend on the language structure, and to a large extent, the access to a system of display, audio and calculation. I am slowly developing the jarvar language, and the embedded ScriptLanguage which is ava...

Re: Battery to power RPi and powered HUB

There could be a problem if you have significant high-frequency AC currents running on your ground lead, but the power-supply bypass caps on the R-Pi should prevent that from happening. I'm an electronic engineer, please explain as you seem to misunderstand the meaning of bypass capacitor as oppose...

Re: education

A large part of linux is from the educational system. There are many advanced research projects using it, with free and open source code. The problem as you have noted, is the lack of simple drill instructor tools, to get those kids in line for making the bank a profit :D. Have you read the magpi ma...

Re: Battery to power RPi and powered HUB

So if the HUB powers the Pi, and the Pi also sends data to the HUB via another USB cable, then an earth loop will form, if the HUB connects the power from the USB in B connector. Any reasonable design should not, as it would use isolation of the supply. Some badly designed USB HUBs may have problems...

Re: RF question

Other options for RF control include the eZ430-Chronos kit. It includes an RX/TX USB stick, which will work with Pi as a USB serial interface, and other stuff on the right band. It will maybe allow the Pi to RX the time too, or sync the Chronos to the net. A full open source gcc-msp430 compiler is a...

Most excellent mag. Just the sort of thing a noob can read. Maybe a TLA of the geek, where one Three Letter Acronym is reported and sorted.

It looks as though Oracle could not release without ARMs permission, and so ARM needs to sign off on it. As express permission to use old deprecated technology may be possible, if ARM wishes to have the maximal promotion of this ARM core. If ARM does not wish it's customers to effectively use it's e...

Re: Berryboot v1.1 - Boot menu / OS installer

Hi Just a little one, is it possible to add .elf boot, so that a single fully linked elf file can be the total system? And use the berryboot file access via a linked header file? Just wondering, as this could make bare bones code easier to develop. Some would say why not have a full kernel, but some...
