CCS/IWR1642BOOST: Data is not coming out from uart pin 5,7 of j6 connector

Arpit Patel
Expert 2040 points
Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642, MMWAVE-SDK

Tool/software: Code Composer Studio

  1.    I want to take & see data from uart pin of j6 connector as per given in iwr1642 evaluation module(iwr1642boost) pdf but there is no data coming out from this pin.
  2.   As describe by ti iwr1642boost has a more than 80m of range but on demo visualizer is not extend from 8m. How can i extend this range?
  3.   How do i get 80m of range in my iwr1642boost?

    Hi Arpit,

    I'll need to ask my team about this. We'll have an answer for you tomorrow.

    Hi Arpit,

    The demo visualizer is intended as an evaluation tool to show device functionality out-of-the-box. I don't think you'll be able to evaluate at much longer distances using only the visualizer since it is capped at about 12 meters.

    The Short Range Radar Lab will allow you to evaluate up to 80 meters. It is available here: dev.ti.com/.../

    I'll need to ask someone else to provide a response on the RS232 Question.

    As per given in iwr1642boost i should get output at uart pin butI am not getting anything on the given pin which is 5 and 7 of j6. My project is to detect the object at turn on the street light .How I proceed ahead without getting any signal on that pin which indicated detected target?

    Here visualizer also has it's limitations then how can i proceed ahead?

    Hi Arpit,

    The UART Data lines are tied to the XDS debugger but if you are looking to probe it on your board you will want to probe the AR_MSS_LOGGER pin 9 on the J5 connect. You will also need to solder a zero ohm resistor at R26 in order to enable functionality of this pin.

    Let me know if you have more questions.

    I am getting hex value on this. How do i find range and velocity parameter into simultaneously meter and m/s unit? and if there is a another method to calculate this in to certain range and velocity parameter suggest  me that method?

    what is range index, velocity index and peak value ? is it range and velocity parameter?

    Hi Arpit,

    The UART output packet format is discussed in the mmWave-SDK Doxygen in the section called "Output Information Sent To Host." It is available at this location of your SDK, C:/ti/mmwave_sdk_02_01_00_04/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html
