Hi,

I'm reposting my question in this group from comp.arch.embedded - as
it was suggested to me that it might be better to do so. In advance to
all reading: this is meant mostly for people who code in C++ for
microcontrollers such as AVR.

So here it goes:

I am making a school project for PocketPC which is to send some data
to mechanic robots controlled by AVRs or other types of microcontrollers
(mostly AVR). The data I send is own designed packet, which includes its
own 16bit CRC. After some googling I found the CCITT ( poly 0x1021 with
0xFFFF init) and other types of 16bit CRCs (XModem, ARC) - I chose to go
with CCITT, but still can go with other type if it makes it easier.

To the subject now - I have no idea what type of compilers are
available for such microcontrollers (AVR etc). What I'd like to know is
there any library with CCITT (or other) calculation function. I'm aware
there are many source codes for that on the web, but I'd still would go
with the library function (just easier for the people to use it) - the
speed is not an issue. It's just easier to point other people to the lib
function in the documentation instead of making them type some code I
present in the doc.

Hope I made myself clear. Thanks for any help, regards
