IWR6843ISK: Interfacing IWR6843+MMWAVEICBOOST with TM4C123GH6PM (Tiva Launchpad)

Part Number: IWR6843ISK
Other Parts Discussed in Thread: TM4C123GH6PM, IWR6843, MMWAVEICBOOST

I am trying to use the IWR6843 board along with mmwaveBoost IC and Tiva launchpad (Part number : TM4C123GH6PM) as shown in the below snapshot.

I want to transfer the LVDS data that is received by the mmwaveICBoost from IWR6843 to TM4C123GH6PM board and do some small processing on the tiva board itself.I would like to know what is the significance of the below pins and is it possible to transfer data to tiva lauchpad.

Also Is it possible to do the processing on the LVDS/UART data given by IWR6843 on mmwaveIC Boost or IWR board it self ? I want to derive two paramters out of my experimentation which i can display on a LCD.

    Hello,

    I'm trying to understand what your need is to connect LVDS data to the TM4C device. You would have to implement a processing chain for the LVDS. Are you trying to acquire LVDS data? Which demo are you basing this on?

    I would recommend that you flash the radar sensor with the hard-coded out of box demo. Using the hard-coded demo will then NOT require that you send a .cfg file to the sensor in order to start chirping. Then connect the UART from the sensor to the TIVA device. The TIVA device can then read the point cloud data from the sensor. You will have to align the pins from the MMWAVEICBOOST to the TIVA in order for correct UART transmission. 

    You can find the hard-coded out of box demo from the Industrial toolbox on TIREX.

    Sir,

    Thank you for the reply. Yes, you do understand it right that we want to transfer the LVDS data of the device to TM4C. We were using the vital sign demo. Our aim is to do wireless transmission of the raw data to another location. Since MMWAVEICBOOST does not have a wireless transmission unit, we were trying to transfer data to TM4C through which we have configured a WIFI/BLE device.

    We will try to run the hard-coded out of box demo and get back to you on this.

    hello,

    LVDS is not supported on the TM4C, you can connect the uart instead.
