AWR1642BOOST: How can I config chirp configuration to enable tx1/tx2 send one by one in mmWave Studio?

Other Parts Discussed in Thread: AWR1642

Hi there,

I have done some programming in Linux using ROS driver of AWR1642 which enables chirp configuration as follows:

chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2

In this case, tx1 and tx2 sends EM waves one by one (chirp sequence: [tx1 tx2 tx1 tx2 ... ... tx1 tx2]). And I could get Doppler info from both transmitters simultaneously. 

However, when I use DCA100EVM to capture raw data in mmWave Studio. I do not know how to set chirp configs to do the same thing as above. I can only use "TX enable for current chirp" in the chirp configuration. How can I get the same result as above?

Thanks in advance.

    Hello Leo,
    You can use the CHIRP Config section in the mmave studio to select the TX you want to use for that particular chirp. For example in the chirp config index [0] you can select TX 0 and for index [1] you can select TX1. Then in the frame config you can set start index as 0 and end chirp index as 1. This would send chirp 0 and chirp 1 alternatively.
