[Tinyos-help] Project on TinyOS

[Urs Hunkeler]

Hi Vaibhav,

The full source code of TinyOS is probably already installed on your
computer. For the implementation of the module that controls the leds,
try looking for a file called LedsC.nc. There are probably multiple
versions because different platform require different implementations.
There is also a file called Leds.nc, which is the interface description
of the module.

I don't know what kind of project you're working on. But trying to build
a whole hardware platform plus software, etc. seems a bit
over-ambicious. If you really want to build all the hardware yourself, I
would still use TinyOS and just write a port for your new platform
(you'd only have to rewrite the lowlevel hardware dependent parts).

However I think it would be MUCH simpler to just use one of the already
existing hardware platforms and just add the sensors that you need. Most
of them (if not all) offer some kind of connector where you can connect
additional hardware. You'd have a ready-made communications platform
that you just would have to extend to your special needs.

Cheers,
Urs
