pic16f877a tutorial

I'm looking for PIC16F877A sample C programs and tutorials.
Thank you very much for your help.

I wrote a great PIC16F877A tutorial for beginners.
It covers everything from how to connect the PIC, to sensors, motors, lights.

hi everyone.
i am newb here...
i just go through this forum and found it quite ineteresting.
fyi,i am a student...electronics student.
i am very interest in pic ..not only theory bt prctcally
for this week,i plan to do basic led blinking..but i dont know how to start it bcoz i dunt have any ide of c language
i plan tu use mplab n c language.
can anyone help me with the source code?
i want to study from the basic source code n develop it..really hope for that
 

You start with mickroC.it is so easy when compare others. Try it.. Free version support upto 2kb
 

I think,MPLAB Hi-tech C compiler is so easy...

PIC Simulator IDE is useful for your simulation.
