IWR1443BOOST: mmWave Studio: sleep time in Lua Script

Part Number: IWR1443BOOST

Hey all,

I'm using mmWave studio and am trying to build a real-time tracking system with IWR1443BOOST and DCA1000.

Right now, I'm controlling the mmWave studio through MATLAB with the code provided in mmWave Studio User Guide. I did the data recording by running the dataCapture_demo.lua through MATLAB. I noticed that there is a lot of sleeping time in the Lua script provided which really slows down the data acquisition process.

My question is: are those sleep time necessary? If I remove the sleeping time, will Lua wait for the function calls to return before continuing on?

Also, I understand that DCA1000 is meant for RF evaluation. So if I wish to build an application such as tracking the motion of an arm, what approach would you recommend?

Many thanks in advance!

  • Hi Ziheng,

    I've asked our DCA1000EVM expert to look into this. Please allow a few days for a response.

    Have you seen the DCA1000EVM Training Video? training.ti.com/dca1000-training-video

    Thank you Akash,

    Yes, I have gone over all the mmWave Training Series including the DCA1000EVM one, but I don't think it covers the sleep time in the Lua script.

    Also, I noticed something interesting about the missing packets and the sleep time, discussed in this post:

    Hi Ziheng,

    The sleep times ensure the previous function has completed before moving on. I recommend looking at the mmWave demos for help with your application.
