AWR2243: AWR2243

Tool/software:

I am using already existing the Cascade_Capture.lua file  for data capture. Is the data capture in this file is happening in sequence? Meaning 1 Tx is transmitting and all Rx are receiving. Not like all Tx are transmitting simultaneously.

    Hello,

    Is this the two chip cascade ?

    Can you please attach the lua you are using. 

    Thanks,

    It's 4 chip board, It's not getting uploaded. Cascade_Capture.lua and Cascade_Configuration_MIMO.lua are the files i am using. Both came with installtion. I haven't change them.

    Yes you are correct. One TX at a time is transmitting to all the RXs. This is defined per chirp using the API ar1.ChirpConfig_mult

    Hope this helps,

    Thank you for the reply.

    I wanted to know if i want only one Tx and one Rx to use throughout my test in this cascaded board what all changes i will have to do in the .lua file? Or do you have any .lua file which uses one Tx and one Rx only for testing. All other Tx and Rx to be powered off throught the test.

    During your Basic configuration, ar1.ChanNAdcConfig_mult you will need to disable the other RXs and enable only one TX and one RX. 

    In this API, first input is device number, next three inputs are TX and next four are RX. 

    ar1.ChanNAdcConfig_mult(1,1,1,1,1,1,1,1,2,1,0,1) enables all TXs and all RXs
    ar1.ChanNAdcConfig_mult(1,1,0,0,1,0,0,0,2,1,0,1) enables first TX and first RX.
    I would also encourage you to use mmWaveStudio to understand the APIs better and be able to turn on and off the TXs you are interested in.

    Thank you for your reply. I will use API to get more comfortable with operations.
    Currently i am using Cascade_Configuration_MIMO.lua provided in mmWaveStudio and proceesing the data using cascade_MIMO_signalProcessing.m. I am getting adcData size as 256*1*16*12. How to map the Tx values. I mean the adcData(:,:,:,1) correspond to which Tx? Tx of device 1 or 4 or any other. Because without this knowlege i will not be able to form the MIMO array.

    I believe it should be arranged as TX1 to all RX (in the sequence of RX1 to 4 starting with device 1), followed by TX2 to all RX, and so on.
