AWR1843AOPEVM: How to set AWR2944 using specifice antenna only?

Hi Edward,

For specific antennae, you have to look for your channel config.

First value represent your receiver i.e for your scenario 15

and Second Value represent your tranmitter i.e 1 for your case.

Now, Value 15 represent the binary number (1111) which means all receiver are active. So if you want your first receiver to be active and rest receiver to be inactive just give the value 1 i.e (0001) and if you want your second receiver to be active give value 2 i.e (0010) and so on. and similar is the case with transmitter as well. hope it helps.

Thanks and Regards

Hi Edward,

I see you are using only one chirp, but your frame end index is 3 so that is not possible. either give 3 chirp configuration or make end index as 0.

For example: In the given picture there are 2 chirp and end index are 1. So, try using this.

Thanks and regards,

Animesh

Which part should change???

Thank you!

Hi Edward,

Can you mention all the change you made in the parameter of original configuration?

Thanks and Regards

Animesh

Hello Animesh:

   Only command changes:

1.  channelCfg 15 1 0  -> channelCfg 1 1 0 

2.  frameCfg 0 3 16 0 1008 100 1 0  ->frameCfg 0 0 16 0 1008 100 1 0

DUT with 1 "chirpCfg 0 0 0 0 0 0 0 1" command

thank you!

Edward

Hi Edward,

Can you tell me which configuration you are using from SDK?

Thanks and Regards

Animesh 

Hello Animesh:

   Only mss.syscfg with MX25V1635F flash QE changes. Radar configuration using SDK default setting.

Thank you!

Hi Edward,

I was asking for which profile you were using like TDM, DDM within that there is .cfg file so which .cfg file you are using for same?

Thanks and Regards
