MMWCAS-RF-EVM: BPM-MIMO setting

Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: MMWCAS-DSP-EVM,

Tool/software:

Hello,

I am currently using MMWCAS-RF-EVM+MMWCAS-DSP-EVM.
mmwave_dfp_02_02_04_00, mmwave_studio_03_00_00_14

Please provide me details about BPM-MIMO setting. I have gone through PDF document available about BPM-MIMO but still needs more clarity.

I have checked the following thread:
e2e.ti.com/.../tdm-mimo-and-bpm-mimo

The .lua script obtained from the above thread was not a cascade setting.

How to set BPM in mmwave studio, I mean more specific settings (***.lua script).

Regards,
Tsuda

    HI,

    Pleas start with a LUA script for cascade board and modify it with the bpm mimo lua script provided in the thread

    --Create Chirps
    ar1.ChirpConfig(0, 0, 0, 0, 0, 0, 0, 0, 1, 0)
    ar1.ChirpConfig(1, 1, 0, 0, 0, 0, 0, 0, 1, 0)
    ar1.ChirpConfig(2, 2, 0, 0, 0, 0, 0, 0, 1, 0)
    ar1.ChirpConfig(3, 3, 0, 0, 0, 0, 0, 0, 1, 0)

    --Apply BPM settings to chirps
    --Apply 0 degree phase shift to chirps 0 and 1; apply 180 degree phase shift to chirps 1 and 2
    ar1.BpmConfig(0, 0, 0, 0, 0, 0, 0, 0)
    ar1.BpmConfig(1, 1, 0, 0, 0, 0, 0, 0)
    ar1.BpmConfig(2, 2, 0, 0, 1, 1, 0, 0)
    ar1.BpmConfig(3, 3, 0, 0, 1, 1, 0, 0)
    Thank you

    Hello,

    Thank you for your reply.

    In the case of a cascade board, do I need to set all RadarDevice?

    ar1.ChirpConfig(0, 0, 0, 0, 0, 0, 0, 0, 1, 0)　→　ar1.ChirpConfig(15, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0)
    ar1.BpmConfig(0, 0, 0, 0, 0, 0, 0, 0)　→　ar1.BpmConfig(15, 0, 0, 0, 0, 0, 0, 0, 0)

    I have an additional question.
    For the BPM shown below, are the following settings correct?

    --Create Chirps
    ar1.ChirpConfig_mult(15, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1)

    --Apply BPM settings to chirps
    ar1.BpmConfig_mult(1, 0, 0, 1, 1, 0, 0, 0, 0)
    ar1.BpmConfig_mult(2, 0, 0, 1, 1, 1, 1, 1, 1)
    ar1.BpmConfig_mult(4, 0, 0, 0, 0, 0, 0, 0, 0)
    ar1.BpmConfig_mult(8, 0, 0, 1, 1, 1, 1, 0, 0)

    Regards,

    Tsuda

    Yes, 

    You will need to configure every chirp.

    Thank you
