here while doing it i need the source code for serial.c ... kindly help
i was writing a program in atmel which contain #include serial.c where this program is missing in my keil compiler can you post me the program or link
"...in atmel..."
What do you mean by, "in atmel"?
"...which contain #include serial.c"
If you really wrote this program, then that would only be there because you wrote it there!
Presumably, then, you didn't actually write this program at all - you have just copied it from somewhere?
Note that #include-ing a '.c' file is not the usual thing to do at all - so it may well be preferable to find some better-written code to copy...
"this program is missing in my keil compiler "
What makes you think that it should be included?
If you want Keil examples, see: http://www.keil.com/download/file/
Also look in the C51\Examples folder in your Keil installation...
"can you post me the program or link"
There is no way to tell the content of a file just from its name; it is impossible to know which particular "serial.c" your program requires!
The documentation for the program that you're coying should tell you details like where to find this file.
