hi guys

i am trying to develop a security system that could be armed and disarm wireless
the code to arm the system would be transmitted using a simple pushbuttom connected to the microcontroller.when you press the button the choosen code to arm the sysyem is transmitted serial to the other pic.i am using rf module in this so i have tested the code but it can correspond with the reciever.

i have atteched the receiving code.

thanks in advance

here below:

You say you use the 16f84. But you have included the header file for the 16f887. Your code will not work because of this. The config bits also belong to the 16887. You can find the correct config bits option for the 16f84 at the end of the 16f84 include file
Also then you post code, please use the code option described here http://forum.allaboutcircuits.com/misc.php?do=bbcode it will make your post more easy to read. You can edit your postings in this forum

 

and also post a circuit schematic.... this could also help in determining if your code is correct....

No the header was just a mistake coz i have change the template without noticing.

This is exceedingly confusing. Please edit your first post so the code is correct. You can not expect to get any help before this is done. And while you are editing use the code option described here http://forum.allaboutcircuits.com/misc.php?do=bbcode#code
And your schematics is also strongly sought after

 

If you would kindly edit your first post and add the CODE and /CODE delimeters around your code. It makes navigating and cutting and pasteing your code multitudes easier.
