S-FSK / FSK API for TMDSPLCKIT V3

Other Parts Discussed in Thread: AFE031

Hallo,

I'started a PLC-project with the TMDSPLCKIT V3 and can't find a S-FSK / FSK API in PLCSuite.

I only got PLCsuite for OFDM-based communication.

So my question is: Where can I get a API for SFSK / FSK communication and what is with the AFE031? Do I need a special API for driving the AFE031 with SFSK / FSK Modulation?

best regards

    Hi PG_, 

    Currently, we are not maintaining the SFSK packages but we have a low-cost OFDM based solution named PLCLite (

    our proprietary solution). The plclite supports low data rate with great improvement on PHY robustness.  You can find the PLCLite s/w package from www.ti.com/plc. Thank you.

    Hi Wonsoo,

    PLCLite is not a good solution for my application, because I have only a few seconds to communicate from one Master to lot of Slaves.

    Is it possible to use the TI_plcSUITE_hal_api of the AFE031 independent to OFDM based communication?

    Hi Wonsoo Kim,

    Why did you write on the TMDSPLCKIT V3 page that:

    PLC software supporting OFDM (PRIME, G3 and FlexOFDM) and SFSK communication

    Our company bought this kit to easily develop SFSK applications, and we where disappointed.

    Hi Mateusz, 

    Sorry for not updating the info.  I am still not very clear why you have to use SFSK solution for your application to meet the goal below. 

    " I have only a few seconds to communicate from one Master to lot of Slaves." 

    I believe that to achieve the goal OFDM technique would be more proper solution in respect with robustness and data rate. If you can share with us your target application and deployment environment details, we will provide you more details. 


    Thanks.

    Hi Wonsoo,

    Sorry for not explanation, but I represent other company than PG_.
    We wanted to use the TMDSPLCKIT V3 to communicate with the device that has implemented the SFSK (a model of smart meter).

    Hi Wonsoo,

    the apllication use 30 (best would be up to 70) devices, which need to be checked in a cyle smaler then 2 seconds. I have a independent DC Powerline and all Device on it are well known (only from own company). So I want tu use a FSK, not SFSK to check device at the same Timestamp in parallel on different frequencys. For speciel Signals I have only 0.5s which schould be send over an other Frequency.

    I think the OFDM scheme PCLLite is developed to be used in one frequency range. So it would not fit my problem.

    So back to my Question about the the HAL-API for the AFE031. Is it possible to use this API with own Modulation schemes? Or is the API designed for OFDM only?

    Regards

    Hi PG, 

    Yes, you can. The HAL lib provides general API to control peripherals so that the lib is not limited for OFDM only.

    Hi Wonsoo,

    is any example for using the hal_api available? Something like bring a defined sinus function on the powerline using the DAC?
