I used RADAR studio and TSW1400 to capture ADC raw data. the data is saved off to C:\ti\mmwave_dfp_00_07_00_04\rf_eval\radarstudio\PostProc\adc_data.bin. What is the format of the .bin file? I used 1 TX 4 RX and 16bit ADC. thanks! -Xinsi Lin

Hello Xinsi,
Please check AWR1xxx Data Path Programmer’s Guide for details about packaged data over LVDS lane.
Section 4.1.4.2 Format Mapping in that documents talks about AWR1642 data mapped to LVDS lanes.
Thank you,

Hello Vivek Dham,
Following your advise, I refer to training.ti.com/mmwave-sensor-raw-data-capture-using-tsw1400-board. In Radar Studio(v1.7.4.0), mmwave-sensor-raw-data-capture-using-tsw1400-board suggest me to select the Application/User UART, Buad rate 115200.
But when I select Buad rate 115200, I can't connect SPI. The "SPI connect" button was stuck.
Then I refer to Radar_Studio_User's_Guide, it suggest me to set the Buad rate to 921600.
When I set the Buad rate to 921600, I can connect SPI successfully.
I'm confused. Because when I do the mmw demo and capture demo, the Buad rate of the Application/User UART is set to 115200.
Why do I connect the SPI successfully in the Radar Studio until I set the Application/User UART to 921600?
Thank you!
Hi Vevek,
I want to clarify more about data format topic.
When default RadarStudio configures 16 bit complex the order of data should be:
RX1-I sample 0 , RX1-Q sample 0 , RX1-I sample 1 , RX1-Q sample 1 .....Rx1-I sample N-1 , RX1-Q sample N-1 , RX2-I sample 0 , RX2-Q sample 0 ……
Questions:
1. The above data order is correct or not.
2. Is there any header between frames?
3. What is the first sample as following figure? Does they align with big-endian or little-endian?
Thanks in advance.
B.R.

Hi Vivek,
My customer used the AWR1642 EVM+TSW1400 to capture ADC raw data, with only Rx1 and Rx3 enabled, got below data view, seems the stored data format is Rx channel interleaved, it cannot be understood as below format. Per my understand AWR1642 only support non-interleaved data output, below data view confuse me. Would u pls help have a look at it?
RX1-I sample 0 , RX1-Q sample 0 , RX1-I sample 1 , RX1-Q sample 1 .....Rx1-I sample N-1 , RX1-Q sample N-1 , RX2-I sample 0 , RX2-Q sample 0 ……
Regards,
Andy
