AWR1443BOOST: Master mode and Slave mode of AWR1443

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1443,

When I use mmWave Studio to configure the AWR1443+DCA1000, I find that Master mode and Slave mode can be selected. Just as the following picture shows. 

Q1 Does it mean that one AWR1443+DCA1000 can work with Master mode and another AWR1443+DCA1000 can work with Slave mode?
Q2 If it is possible, how to realize this configuration?
Q3 If it is possible, does it mean that two awr1443 can transmit or receive signal simultaneously?

  • Hello,

    Master/slave mode in mmWave studio are there for cascade devices which is supported only in AWR2243P and AWR1243P. You cannot use these studio features for AWR1443. 

    But if you still want to connect multiple AWR1443 devices, you can refer to the below threads:

    Hope this helps.

  • Hi, thanks for your reply. 

    I have read the thread. If one laptop was used to control two awr1443boost, the SPI connection between awr1443 boosts should be taken into account. But I have two laptops and two awr1443 and two dca1000, and I just want to connect two awr1443 boosts so they can transmit and receive chirps simultaneously. 

    So does it mean that I just connect the MCUCLOCK pin of the first awr1443 to SYNC_IN pin of the second awr1443(also, the ground pins between two awr1443 boosts should also be connected) and then the two awr1443 boosts can work simultaneously?

    Thank you.

  • Hello,

    I recently came across a thread which I thought might be useful for you :

    Please let us know if you need further information.

    Have a good day!!

    I have read that thread. I don't have another MCU that can provide SYNC signals for two AWR1443 so I cannot use the method proposed by that thread. According to the thread below, the first AWR1443 can provide synchronization signals to the second one, so I want to try this method to synchronize the two awr1443 boosts. 

    According to this thread, I need to change the code before the synchronization betweent two awr1443 so that the MCUCLKOUT  pin of the first awr1443boost can be remapped to have sync signal that can be provided to another awr1443. 

    But I don't know how to use this code and what is the MSS_Init?

  • Hello,

    Forwarding your query to our software expert. He will see to it as soon as possbile.

    Thanks!

  • Hello,

    In the current default scenario, mmwave studio can have connection with signle AWR1443BOOST EVM connected to the PC.

    Even though you connect multiple EVMs with single PC, mmwave studio can communicate with one only.

    What is your main intention to connect two AWR1443 boards, if you provide more detail or flow diagram what you are planning with AWR device then we can provide more hits here.

    Yes, I know mmwave studio can have connection with single AWR1443BOOST, but now I have two PCs, two AWR1443BOOST and two DCA1000, so the two AWR1443BOOST can be controlled by these two PCs.
    I just want these two radars to transmit and receive Chirps simultaneously. Now I find that there are two pins on AWR1443BOOST, namely, J6.18(SYNC_OUT) and J6.9(SYNC_IN). According to some documents of TI, J6.18 is an output port that can output frame synchronization signal and J6.9 is an input port that can provide frame synchronization signal for frame start. So if I connect J6.9 of one radar with J6.18 of another radar(the GND pins of two radars should also be connected. ), will the two radars can transmit and receive Chirps simultaneously?

  • Please refer this thread which explains about synchronized two AWR devices for framing.

    I have already read that thread. According to that thread, the MCUCLKOUT  should be remapped to have frame sync signal. But I think this step could be omitted. Now I find that there are two pins on AWR1443BOOST, namely, J6.18(SYNC_OUT) and J6.9(SYNC_IN). J6.18 is an output port that can output frame synchronization signal and J6.9 is an input port that can provide frame synchronization signal for frame start. So if I connect J6.9 of the first radar with J6.18 of second radar(the GND pins of two radars should also be connected. ), then select hardware trigger mode when configuring the first radar, will the two radars can transmit and receive frame simultaneously?

    Thank you. 

  • SYNC_OUT line mainly being used in the cascade mode, where device provide pulse at this line to trigger frame on other connected slave device.

    In case of single chip like AWR1443, alternative of SYNC_OUT is over MCUCLKOUT and internal frame start signal is pinmuxed to this MCYCLKOUT pin which connectes to other AWR device (on SYNC_IN) line for frame trigger.

  • Hello,

    According to that thread, MCUCLKOUT  pin of awr1443boost can be remapped to have sync signal, and we need to run the following codes. 

    But I don't know how to use the code, could you gave me some details about how to run the code?

    Thank you.

  • You need to add this code in mss_main.c file and rebuild the application.

    In the application there is already a pinmux part for UART, you can use this later to that.

    Search for 'Pinmux_Set_OverrideCtrl' in main.c file of mmw demo if AWR1443 in mmWave SDK v2.1
