AWR1642BOOST: Capture Demo, how to use this demo to get ADC data twice?

Hi,

I had got the ADC data with CCSv7 successfully. And I have read mmwave_sdk_user_guide.pdf.

Here is my operations:

step1, I programed ccsdebug.bin to the flash and reboot the board.

step2, I loaded the capturedemo_dss.xer674 and capturedemo_mss.xer4f with CCS.

step3, I send the config comand to board by UART as follows:

flushCfg
dfeDataOutputMode 1
channelCfg 2 1 0
adcCfg 2 1
adcbufCfg 0 0 1 1
profileCfg 0 77 20 5 80 0 0 40 1 256 8000 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
frameCfg 0 0 128 1 20 1 0
lowPower 0 0
sensorStart

it works well, and I save memory start address at gDataCube(0x20000000) with size 32768.

Finally, I plot the range FFT

So, if I want to get more data, I have to repeat step2 and step3.

Can you tell me another ways to get more data simply and rapidly?

Thanks,

Jinjun

Hello Jinjun
Are you looking at a streaming data capture ?

You can do this by streaming the ADC data over the LVDS and capture it using the TSW1400EVM .

I was going to start my own thread to ask this question but it seems relevant here... Evidently the TSW1400EVM is on back order, would any of the other TSW140x boards work for capturing the ADC data from the AWR1642BOOST?

Hi,Raghu,

My TSW1400EVM is on the way, but it maybe takes servral weeks.

Now, I'm looking for some ideas to get ADC data with only AWR1642BOOST .

Can you help me?

Thanks,

Jinjun

Hi,
Existing capture demo can store ~639KB of adcData [max dataCube memory ( .l3Data section)].
With this size either you can increase numOfChirp, numOfSample or numOfFrame but the only thing you need to take care that total amount of data must be within that above-mentioned max dataCube memory.

Jitendra

When you say that you're flashing the ccsdebug.bin on the board in the first step, do you mean the capture_demo.bin?

Hello Carlos,
It is the binary that is available in MMWAVE-SDK "$mmwave_sdk_01_01_00_02\packages\ti\utils\ccsdebug".
