| I am trying to data transfer through two cc2420 zigbee modules using pic18f4550 but it is not happening, the cc2420 module is not recognizing. Please help me with it. |

first steps....
You should post either a schematic (through a 3rd party service) or a link to the modules you're using. All Zigbee devices are 3V and the PIC is a 5V device. So I need to know how the hardware is connected.
2nd....
Have you got your PIC to run the '1Hz LED' test program? This is just a simple 'toggle' and LED on a pin to confirm your hardware is correctly wired, that the proper 'fuses' have been chosen and that the compiler/programmer are functioning right. Since the 4550 has internal USB, it also has a LOT of possible 'clock' configurations so it is very, very important to confirm you can toggle an LED !!
3rd....
Once all that works, consider connecting the two PICs without the Zigbee modules. Again there are several ways to use them, however the serial ttl is perhaps the simplest and easiest to test, though I never had any good luck with them, gave up and they're collecting dust...

You're keeping us in the dark by drip feeding information.
You must tell us how you KNOW what is working and not working.
Start by answering Jay's questions.

I don't think a driver file exists for the cc2420 and the CCS compiler.
Some people try to convert Microchip C18 compiler code to CCS:
http://www.ccsinfo.com/forum/viewtopic.php?t=42920
But you are asking the same question on the Microchip forum:
http://www.microchip.com/forums/m836213.aspx
I don't think you have the CCS compiler or the Microchip C18 compiler.
I think you googled for cc2420 and found two forums that mentioned the
cc2420.
I think you should search the net for a complete, working project with
the cc2420. Find someone who has done the whole project and posted
the code and the schematic for download. Then just copy it. |
