CC1125: FEC implementation in CC1125

christy jude

Part Number: CC1125
Other Parts Discussed in Thread: CC1200

I have used CC1125 module for our RF communication.FIFO based data transfer has been used in our project.

We used 4kb file for data transfer,While receiving of packet ,CRC error happening in some packet,so we have decided to implement the Forward error correction (FEC) to solve this CRC error

And I have gone through the TI website we have found DN504 and DN507 application note implementation of FEC.

I have implemented this code in my project.In decoding method 4 bytes of RXFIFO data has been read to decode the data.

so that we missed some packets while faster communication.Is there any option to read whole bytes of RXFIFO to decode the data.

please help me in this issue.

Hi,

You can also try using DSSS PN mode for better sensitivity.

See section 5.2.5 of user guide http://www.ti.com/lit/ug/swru295e/swru295e.pdf

Hi,

I am afraid the app notes are the only examples we have for FEC. You could try some open source libraries.

You could also use CC1200 which has a FEC hardware block. CC1125 and CC1200 devices are also pin compatible.
