RF Transmitter with CC1100 Development

cc1100 pcb

I try to send data via RF with CC1100. After I read Datasheet with carefully and try to develop it.

I not much knowledge in RF. I don't understand most configulation bit. I Use SmartRF Studio to help. But it still not work.

I found some problem.

1. I not have spectum analyzer to check that signal. It make me doult the problem from Transiver or Receiver path.

2. Anyone have the library of this module in CCS. If yes can u give that code for me.

Thank you for all.

cc1100 sample code

You can read "CC1000 debugging hints and troubleshooting" for reference.
It is not possible to do low level RF design without some basic RF instruments,like RF signal generator,spectrum analyser etc.

cc1100 source code

At first, RF is not easy...

CC1100 is a Chipcon's product, but the company belongs to TI.
refer to the site **broken link removed**

1. Check the PCB layout
: recommend exactly same as the reference design.
gerber file is opend. review this first.
PCB Antenna pattern is opened, too.

2. the passive elements, such as R/L/C, is important at the RF analog part...
: recommend exsactly same as the reference design.
a little difference would cause the errors.

3. Understand the operation of the IC.
4. port the other MCU's open source code to PIC...


the CC1100 is the same structure as CC2500.
but the difference of PCB pattern and schematics is reasonable...

I've ported the C51 or MSP430 source to dsPIC.
It's not difficult, but be careful about some difference of MCUs.
