Hi all,

I'm doing a project on wireless sensor networks. So i have designed sensor nodes using 16f877a micro controller (without using existing sensor nodes). I have written a program node to an en ...

Hi all,

Due to the limited memory on micro controllers, it is better if i can used dynamic arrays which can grow at run time, rather than having fixed size arrays.

I need to create a dynamic arr ...
