AWR1843BOOST: Serial Communication in Linux(ttyACM0, ttyACM1)

Part Number: AWR1843BOOST

Hello,

  When I connect AWR1843BOOST and Raspberry Pi with USB cable, ttyACM0 and ttyACM1 are activated.

  So I want to have a serial communication with these ports by python serial modules, but I don't know the format for sending message to AWR1843BOOST.

  I used some code from a commit at github, but I think it doesn't fit for my case so I want to know the standard format.

  What I saw format in the github commit was like 'sensorStop ...... sensorStart'

  The commit which I used is in below link.

  https://github.com/ibaiGorordo/AWR1843-Read-Data-Python-MMWAVE-SDK-3-

  And my environment is below

  Device : AWR1843BOOST, Raspberry Pi 4 model B (with OS Raspbian 10)

  SDK : mmwave SDK 3.04 (I installed at Ubuntu which is the virtual machine on Windows, and I moved the SDK folder to raspberry pi.)

  And I put the power by GPIO(3.3V, GND) and used USB port(J8) for data passgage. Nothing else I did on my AWR1843BOOST.

    Seungjae,

    You need to connect a power supply rated for 5V and at least 2.5A and connect it to P6. Do not apply power through the 3.3 GPIO pin. This will not be sufficient for powering the entire device.

    When you flash the demo application that is included in the mmWave SDK, you communiate to the device using the CLI commands that are described in detail in the SDK User Guide. The SDK User Guide is located in this location:

    C:\ti\mmwave_sdk_03_04_00_03\docs

    You can also see example profile configurations in the following folder location:

    C:\ti\mmwave_sdk_03_04_00_03\packages\ti\demo\xwr18xx\mmw\profiles

    Regards,
