AWR1642: How to read the Radar Front-end of MMIC

Part Number: AWR1642
Other Parts Discussed in Thread: IWR1642

Hi Champ

There's a question that customer would like to clarify.

The following figure is the IWR1642 block diagram.

Customer would like to know if they're able to read the data of LNA, ADC values as well as PA.

They want to read the Rx value and Write Tx value through the MMIC internal register or programmable values.

Could you please let us know the method to read the Rx power and write the Tx power of the respective Antennas? i.e. let us know how to adjust the respective antenna' power strength accordingly if needed.

* How to read/write OOK, LNA, LO values of RADAR frontend? 

Regards, 

Jack

    Hi,

    The RF front end is controlled through the mmWave Link API. These APIs run always on the host. The host communicates with the sensor

    • Through mailbox for devices integrating the Programmable Processors: AWR16xx, AWR18xx, AWR29xx
    • Through SPI or I2c for sensor only gen1 devices: AWR12xx
    • Through SPI or I2c for sensor only gen2 devices: AWR22xx

     

    The source code for this API is provided in the Device Firmware Package that can be downloaded from this link.

    www.ti.com/.../MMWAVE-DFP

    For AWR1xxxx devices please download Gen1 DFP. For AWR2xxx devices please download Gen2 DFP.

     

    The documentation for available commands is provided in the Radar Interface Control (RIC) doc provided in the package:

     

    C:\ti\mmwave_dfp_0#_0#_0#_0#\docs\mmWave-Radar-Interface-Control.pdf

    Please review this document and let us know if there are additional questions
