IWRL1432: Raw ADC Streaming with SPI

Hello.

Can you please provide the individual screenshots in the post itself?  In addition, have you referred to the SDK documentation regarding streaming data over SPI?  It describes how to set it up for streaming with FTDI in the section 

Steps for SPI based streaming.

Sincerely,

Santosh

IWRL1432 Boost with flashed demo (changed sysconfig and compiled in CSS, then flashed in visualizer GUI with built .appimage):

“motion_and_presence_detection_demo_xwrL14xx-evm_m4fss0-0_freertos_ti-arm-clang”

->sysconfig changed in CSS with ADC Streaming via SPI enabled:

.cfg Sent via Visualizer.exe GUI

C:\ti\MMWAVE_L_SDK_05_04_00_01\examples\mmw_demo\motion_and_presence_detection\profiles\xwrL14xx-evm\MotionDetect.cfg

Changed parameters in \MotionDetect.cfg:

adcLogging 2

lowPowerCfg 0

After sending MotionDetect.cfg: Terminal of visualizer.exe still showing “SPI ADC Streaming is not enabled”.

 From TI Resource Explorer: xWRL1432 MMWAVE-L-SDK  05.04.00.01:

“RAW ADC data streaming / Steps for SPI based streaming”

Connected as seen in picture:

Figure 1: C232HM-DDHSL-0

SWITCH S1.6 ON

adcDataSPIFTDI.exe:

Tried different Parameter Settings. .txt is generated but only containing “-1”

adcdata.txt is generated with only containing “-1”

Also tried to configure Radar with CLI Tool C:\ti\radar_toolbox_2_10_00_04\tools\studio_cli\gui\mmw_cli_tool:

With same .cfg and changed mmwaveconfig.txt (port/ADC/filepath etc.)

mmwave_studio_cli.exe is connecting the device. Configuring stops after few Parameters “done” without error Code.

Questions:

1 Is there a more detailed description of the correct order of the steps below? It says there, that i have to do the steps of adcDataSPIFTDI Application before "SensorStart" command, but as soon i have sent the .cfg via visualizer the device has already executed "SensorStart"?! Whats the correct approach in this case? sending SensorStart with teraterm or mmw_cli_tool?

2 How do I use adcDataSPIFTDI.exe with TeraTerm/CLI Tool/Visualizer.exe to get raw Data via SPI? Is it necessary to also activate MCSPI in syscfg?

(The Default Demo of this example without ADC rawdata is working with visualizer, plots showing data etc…)

from: xWRL1432 MMWAVE-L-SDK  05.04.00.01/ RAW ADC Streaming/Steps for SPI based streaming i used this: 

• Ensure that switch S1.6 is ON.
• Run the demo and use configuration with "adcLoggging 2" to enable this feature.
• Run the adcDataSPIFTDI.exe application located in tools/spi_adc_streaming folder after issuing the configuration (via Visualizer or serial term etc.) and before the sensor start command is sent to device.
• Give all the inputs to adcDataSPIFTDI application like Device Type, Number of ADC samples, Number of chiprs in burst, Number of burst in frame, Number of Frames, Number of Rx Antennas as given in configuration file. Ensure that this is done before "sensorStart" comamnd is sent.
• After the demo starts, Raw ADC Data for given number of frames will get stored in a adcData.txt file in spi_adc_streaming folder.

Hello.

Let me look into this and I will have an update by the end of the day tomorrow.

Sincerely,

Santosh

yes, i am building the demo after i changed syscfg. I managed to send all the commands through Putty terminal, so the connection should  be ok now("done" after adcLogging 2 command). Unfortunately my 1432 Board is defect and i had to switch to a IWRL6432AOP. As not to mess up this post, i created a new question in this forum. I think I'm making mistakes when choosing the right parameters for .cfg File and adcDataSPIFTDI. I am not getting any error message.
