AWR1642BOOST: Question for AWR1642BOOST

Annie Liu

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: DCA1000EVM

Hi Team,

Version of AWR1642BOOST is ES2.0 and version of Mmwave SDK is 2.0. Customer wants to know how to get raw data without using DCA1000 or TSW1400?

Thanks.

Hi Annie,

if one frame of raw data is sufficient, i.e., real-time capturing is not crucial, have a look on the mem_capture test. It should be described in the SDK User Guide. Possibly helpful threads include https://e2e.ti.com/support/sensors/f/1023/t/818840

Customers is unable to understand this formula. He would like to know where can the specific data be found?

Thanks.

Hello Annie,

It is highly recommended to using the DCA1000EVM for raw ADC data capture. If you plan to use just the mem_capture test application then you are limited by only 1 frame data . This may not be of much help to the customer whould would like to develop post processing algorithms using the raw data.

Thanks,

Hi Raghu,

formula: Total Size in Bytes = Num ADC Samples × Num RX Channels × Num Frames × Num Chirps × Num Bytes Per Sample

The customer has the following questions and needs your help.
1. How to calculate the total size of the data?
2. How to read using MATLAB?
3. What does the raw data read out mean?

Thanks.

Annie,

As mentioned you will need to setup the numframes = 1. You will not be able to collect the data if you have the infinite frames.

Total Size in Bytes (1 Frame )= Num ADC Samples * 2(I, Q) * Num RX channels * 2(16bit)

A1: Total size of 1 frame is as shown above.

A2: Save the CCS memory and then use this data file to read from the MatLab.

A3: Raw data readout is the direct data from the CSS memory.

BR,

Raghu
