CCS/AWR1443BOOST: High Speed Interface (LVDS/CS12) and using Communication Interface callbacks

Saad Ahmad

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1243, AWR1443

Tool/software: Code Composer Studio

Hi,

I had two quick questions. I was watching the mmWave radar programming model video and it said LVDS/CS12 was used with the AWR1243 since the ADC data needs to be sent to the external processor. Does that mean we don't need to use it for the 1443? How would we communicate with the front end?

My second question is what does it mean when it says "The mmWaveLink framework is ported to different platforms using mmWaveLink client callbacks"? I found this in the "Porting" section of you Doxygen documents for mmWavelink. What platforms does the framework need to be ported to and why?

Thanks in advance

    Hello Saad,
    The AWR1243 device a front end only MMIC. The ADC data is sent out to an external processor and all the processing is performed on that. AWR1443 is a single chip radar sensor, along with the front end it also has Hardware FFT accelerators and user programmable R4F micro controller . This enables basic objection detection and some processing to be done within the AWR1443 device.

    The mmwave Link framework is something that would be used in AWR1243 context on an external processor and hence its mentioned it can be ported onto external processor of your choice.

    To add to my above comment, incase of AWR1443 the front end is programmed using the code written on the R4F within AWR1443.

    Oh i see so since the AWR1243 needs external processing power, it needs to use a High Speed Interface to communicate with it?
    Whereas the 1443 already has a programmable micro controller on board and a front end.

    That is correct.
