AWR1443BOOST: 2-TxAzimuth-enable, 4-Rx-enable

Zhengguo,

For all development purposes, the Tx/Rx antenna are configured in the chirp configuration .cfg file. An example of doing this can be seen here: e2e.ti.com/.../622987

Thanks for answering my question. I appreiciate your timely responce. In fact, I got to know that there's only one RX antenna IS USED despite all the 4 RX antennas ARE ENABLED from another TI employee who is a man behind the design of the board. To support my argument, I showed him the 1 TX and 4 RX visulizer run report (via email that I sent to a friend of my supervisor and then forwarded to this TI man). However, as per his responce, still there's only one RX antenna is used. So I'm guessing Enabled only means ready to be used rather than actually being used.

I didn't follow up with his responce because it was a conference call , and I am an intern in the company. I felt like I'm waisting other guys time if I chased until I got to understand. Plus, there're plenty of internet resources where I can seek for help.

So my response to you is that "the number of enabled RX antennas" may be different than "the number of RX antennas that is actually being used".

Also during my further research into this topic, in one of the header files which I provided below I found a few lines that are related to this topic. According to these lines I assume that "for an RX antenna to be used it first needs to be ENABLED, then it also need to be activated before it could finally be used."

Headerfile name "cbuff.h"

lines 319-333
/**
* @brief The receive channel is inactive and is not to be used
*/
CBUFF_RxChannelStatus_INACTIVE = 0x0,

/**
* @brief The receive channel is active and ADC data associated
* with the channel will be transferred.
*/
CBUFF_RxChannelStatus_ACTIVE
}CBUFF_RxChannelStatus;

Please help me figure out how do I activate all the RX antennas if my assumption turns out to be what's going on here.

Thank you so much,

Zhengguo Sun.

i don't know how to code, that's why I can only dig out some commenting lines in the "c files" and "h files". learn coding is in my plan. will do in the near future. ^_^

Zhengguo,

Again I'd recommend making sure all the antenna are enabled in the chirp configuration file (.cfg) and then working with those enabled antenna in the .c file. Can you confirm you've done this? Can you confirm that you've enabled all 4 antenna in the .cfg file but less are being used?

Zhengguo,

If you're looking for an introduction to programming, I'd recommend you look at TI-RTOS Training Workshop.

Cheers,

Thank you, Akash.

The following is my cfg file.

1. sensorStop
2. flushCfg
3. dfeDataOutputMode 1
4. channelCfg 15  1 0
5. adcCfg 2 1
6. adcbufCfg 0 1 0 1
7. profileCfg 0 77 7 6 57 0 0 70 1 100 2000 0 0 40
8. chirpCfg 0 0 0 0 0 0 0 1
9. frameCfg 0 1 2 0 50 1 0
10. guiMonitor 0 0 0 1
11. vitalSignsCfg 0.15 0.7 256 512 0.1 0.1 0.05 10000 10000
12. sensorStart

Based on the "15" on the line 4 (channelCfg), I believe there are 4 RX antennas enabled. But I don't know how to locate these antennas in the .c file. Plus, is it possible to change variables of these antennas in one .c file without making some appropariate modifacations in other .h or .c files?

Also, what does the guiMonitor line in the .cfg file do, last Friday I ran the GUI with all parameters set to 0 for the guiMonitor line, the GUI still ran without causing any issue. 

Thank you for your help.
