AWR1243BOOST: mmwavelink_example configuration

Part Number: AWR1243BOOST
Other Parts Discussed in Thread: AWR1243

I am using mmwavelink_example to configure and run 1243. In my config file txPhaseShifter of rlProfileCfg_t is equal to 0 while I found this in AWR1xx_Radar_Interface_Control.pdf: 

So I am not sure how to set up this one... Is this one going to have an influence on the phases between different tx antennas?

    Hi Tiancong,

    The txPhaseShifter settings can only be used with AWR1243P - this part is not yet released. On this part, you will be able to set phases individually on each TX antenna in steps of 5.6 degrees.

    With the regular AWR1243 device, you can only program these fields to values of 0 or 180 degrees. Each phase shifter is controlled by a 6 bit setting (bits 7:2, bits 15:10, and bits 23:18) of the 32-bit txPhaseShifter word, and the other bits need to be set to 0.

    Hope this helps.

    Best Regards,
    Anand
