can any one give me a c code for making some led's on and off
i want it to work as encoder/decoder
atleast for 13 buttons

 

In order to get help, you will need to define quite a few things before anyone can even help, for starters....

What compiler will you be using to compile the C code?
What oscillator speed did you choose?
What modulation are you using for the RF? or are you using IR?

I could go on and on with the questions, but I think you need to elaborate on what you are trying to accomplish, and with what.

IMHO, You would be better off just using some off the shelf encoder decoder pairs, those can be used without programming Pic's, check out this site >>http://www.rentron.com/PicBasic/RemoteControl.htm they have all sorts of IR and RF modules along with encoder/decoders. No need to reinvent the wheel so to speak

 

MICROC
4MHZ
am using RF 315 mhz

 

Hi, this could get you started. http://embedded-lab.com/blog/?p=148 Although he is not using the same microcontroller but you could get the idea if you'll read the whole article.
