Re: Newb sensory

Don't forget a heat gun and some freeze spray.
Very handy to get quick temperature extremes.

Where are you measuring that frequency?

Re: Programming the ARM chip

ALL the USB-RS232 converters are based on the FTDI chipset. No they are not, many use the Prolific chipset. http://www.prolific.com.tw/eng/products.asp?id=59 Many of the available USB to serial converters are based on these and most Linux distros come with the drivers for them. From the Prolific we...

Re: Pi Emulator?

Thanks but QEMU+Debian is for a Virtual Machine, I'm looking for an emulator. Errrr, and the difference is??? You do realise what the "EMU" in QEMU stands for?! ;) OK, but does QEMU completely mimic the Pi so if I want to try out a bare metal OS and don't have a Pi yet, I could use the emulator to ...

Re: Pi Emulator?

Search for Qemu. You should be able to find a link where you can download a ready-to-run Qemu+Debian install for Windows. just a case of unzipping the download and then running the contained batch file. Sorry but I do not have the URL to hand. Thanks but QEMU+Debian is for a Virtual Machine, I'm lo...

Pi Emulator?

Anyone know if a Pi emulator exists (for Linux or Windows) or if
someone is working on one?

Did a quick search on the forum and only found Speccy emulators.
What I would like to have is an emulator that mimics the Pi either under
Linux or Windows.

Re: Bare Metal Robots

That code sample has made me nostalgic as it does resemble BBC basic - ahh - the smell of an overheating powerpack, loading from tape, flashing colors that could induce epilepsy, economic programming ... simpler times ... how did it all get so ... complex? If DexOS can let us have FBasic_L.inc as a...

Re: Assembly Code

I suppose we could discuss/argue over the benefits of assembler ad nauseum
but let's leave it as some people think it's great, some will use it now and again
whilst others think it's a waste of time.
Vive la différence.

Re: Assembly Code

Wouldn't it be easier to teach them C with embedded assembler? IMO, no. C can be very off putting to a beginner and over complex, both in the syntax and the compiler directives. It's much easier (and nooby friendly) to ease them into programming using BASIC like macros and when they have built up e...

Re: Programming the ARM chip

@tufty
Quite right.
Just mentioned FASMARM as an alternative to gcc if using assembler.
Most folks would probably try gcc simply because it's included with the
Debian Distro.

The drawback with Eclipse is it's size.

Re: Programming the ARM chip

@mole125 Makes sense to me. I also found FASMARM which is FASM for ARM. http://arm.flatassembler.net It can produce Linux elf executables and straight binaries. EDIT: Been playing around with FASMARM and rather like it as it has two advantages over gcc (IMHO): Syntax is much less convoluted then usi...

Re: Programming the ARM chip

For native RasPi development I believe the Debian release includes GCC so you don't need to cross compile and don't need to build a tool chain. Can gcc produce straight binary (compiled) ARM bytecode which would run as is much like NASM? (i.e. no elf headers, relocation code, bss,data & code sectio...

Using VirtualBox with Debian image

Hi all

I have downloaded the Debian image and unzipped it.
When I try to open the .img with VirtualBox it says non supported image.
Can anyone please tell me what I'm doing wrong.
I'm using XP.
