TI CC1101 Radio Project

[Zebryk]

Anyone have experience interfacing to TI's CC1101 series of radios via SPI?

Hi Zebryk,
I'm working on a project similar to yours so perhaps we can learn something from each other. My radio is a KFR transceiver from D6 Labs, and is based the SX1272 chip from Semtech. It uses SPI communications. I've searched this Forum and found the following thread which discusses SPI issues among other things:

Forum member Paul has posted some code at post #5 which I have found useful as a guide. Based on this info I have put together some code to just test the send and receive function of the Pic to the KFR radio via SPI. Unfortunately, it is not working as yet ... I'm still trouble shooting. If you are interested I can post my code ... it is very simple.

I found this whilst looking for someting else.....

Maybe of use ? :

Thanks Andy,

Quite interesting but vast.
Can you share any background?

Hi

Sorry I haven't used the radio .... I was looking for something else and remembered your post here....So posted link!

I used the 900MHz Anaren radio module that uses that chip and what a mental workout, but got it working.
I found an article in Nutsvolts that helped me structure the sequence of events in order to get it working right. The code is in C+ but was able to decipher what to do.

Attached is a copy of the article.

Texas Instruments SmartRF Studio also helped with more insight. It provides all the info on every parameter that sucker uses.

Let me know if this is relevant and need some sample code. I used it with a PIC16F685 and PBP 2.5 or so back then.
