Thread: HELP: which lang to learn for embedded device?

Dear all,


I want to port a perl script(written by me) to C or C++ for embedded device like ADSL router, IP Camera...etc. What the script does is login a server and update the IP address of a DNS record. I do not know C or C++, so which one should I learn to do the job? Is C more popular for embedded device?

The perl scipt can be downloaded here:
3update v0.8

And a commnication example:

Yes. C can produce smaller, faster code since it dosen't have the same overheads as c++ and space/CPU speed is offen at a premium on an an embedded device.

Also many people find c easier to learn first.
