Handheld software development
Posted by binary-nomad@hotmail.com on April 27th, 2006


Hello!
Can someone tell me if there is any way to replace the "OS" that
manufacturers provide on various types of handheld devices, eg. the
Gizmondo, PSP, different PDAs....., and replace it with something else?
Also, where is information on these devices (technical docs) and how to
program them? (I'm just a hobbyist, not a big software company of any
kind). I'd like information, for example, on what CPU it has, how much
memory, is there a ROM of some kind and what does it have on it, and
also how to program any other hardware that may be there, eg. a USB
port, or camera etc.


Thanks.

It depends widely on the device. There is an active project getting
Linux to run on Ipaqs (google for linux ipaq for information). It
used to be possible to get an SDK for the Palm Pilot; presumably
that's still the case.

I looked into this a couple of years back; it was at that point a somewhat
immature project, and not exactly ready for prime time. But it showed
promise, and seemed to have some official support. However at that point it
seemed nothing had happened for a fair while...

OTOH, the iPAQs (amongst others) run WinCE Pocket PC, for which a VC++ dev
environment is a free download from Microsoft, along with emulators and
various other bits. Works well. One downside is that certain things like
Bluetooth use 3rd-party stacks, for which the APIs are not free - we made do
(for a prototype) with a nagware version, which worked fine (if you ignored
the nag screen...).

The closest thing to an open-architecture programmer-oriented handheld
you can get is the GP2X (http://www.gp2x.com/)

The GBA itself has no OS, is easy to program (in an emulator), and well
documented too.

You can also look at the host of Linux projects for various PDA's. Most
of the source code are great fun(in a sadistic sense) to read.

It very much depends on the device and how "open" it is.
I think it is quite easy for PDAs, more complicated for PSP.

Google.

Gameing handhelds which are easy(1) to program (even with simulators
on PC) that come to mind: Atari Lynx, GP32, Gameboy (various), Sega
GameGear.

(1) "easy" in the sense of "you get a lot of information". For some
of these you need to have some experience writing assembler :-)

I'm still toying with getting one of these myself. I do like a retro game
and Mario Kart on SNES is gameplay perfection - no-one has ever made a
better game IMHO.

However, Nokia bring out the N80 next month and that looks like fun to play
with as well. Not so much for the gameplay but using the wi-fi to get TV
progs I've stored on my PVR to watch on the phone on the train is going to
be great.

Yes.
I ran linux on an Ipaq for a while.
