AWR1243: How to control multi radars with mmWave Studio?

Part Number: AWR1243

Hi, I am trying to have multi radars (2 radars now) connected to PC and capture ADC data, but I have trouble controlling them all at the same time. I am confused about the input parameter "RadarDeviceId" in functions: FunctionName_mult(), what does the "ID" means? And how to use them to control two AWR1243?

Also I found that when I the want to run command "ar1.Connect_mult(RadarDeviceId=1, ..., ...)", the software would, in fact, execute "ar1.Connect_mult(RadarDeviceId=0, ..., ...)", RadarDeviceId=0 but not 1. And the command "ar1.Connect_mult(RadarDeviceId=0, ..., ...)" would result in connection error and return -1. I tried to add a radar device with "ar1.AddDevice(RadarDeviceId)", but "ar1.AddDevice(RadarDeviceId=0)" result in error: "Power on one device at a time", and "ar1.AddDevice(RadarDeviceId=1)" just make the software break down and closed.

I am really confused about those problems. Thank you for your help and looking forward to your advice!

    Chengzhe,

    Can you provide some information about your setup? Are you using two AWR1243BOOST EVMs? Do you have any additional hardware? Are you trying to use the DCA1000 or the TSW1400?

    The short answer to your question is that mmWave Studio is capable of controlling multiple radars but that is only in the context of a cascaded AWR1243 setup. This is the case because one of the AWR1243 devices has to be designated as the master device and the other AWR1243 has to be designated as the slave device. If you are trying to use two AWR1243BOOST EVMs with mmWave Studio, this will not work. And it would not work trying to use two DCA1000 EVMs at the same time to capture raw ADC data.

    mmWave Studio is only designed to be used to control multiple AWR1243 devices in a cascade setup.

    Hi Kyle,

    Thank you for your reply! Your advice is very helpful because I was trying on two AWR1243BOOSTs with DCA1000 boards, now maybe I should try cascade AWR1243 devices. Could you tell more about that? Or do you know if there are any documents about the cascade devices?

    Thank you!!

    Chengzhe,

    The 4-chip AWR1243 cascade reference design is something that TI is planning on releasing in the future. I cannot provide a release date at this time unfortunately. This single board design features 4 AWR1243 mmWave devices that are controlled by a TDA2x host processor.

    This whitepaper can provide some more detailed information about our cascade solution: www.ti.com/.../swra574a.pdf
