Hello,

I need some help with the Position2Go C Comlib. I want to read the data from Target_Info_t for example the radius.

I included EndpointTargetDetection.h in extract_raw_data.c.

I registered the callback with ep_targetdetect_set_callback_target_processing() and called ep_targetdetect_get_targets() to get the targets.

The callback funtion which I call with ep_targetdetect_set_callback_target_processing() has the parameters of Callback_Target_Processing_t. In the function I want to read out the struct Target_Info_t and print the data.
 
I read the documentation and basically imitated the way it was done with the ADC samples.
 
But unfortunately it doesn't work.
Am I doing something wrong?

May somebody help me with this?

Hello @user19 ,

The code you developed is giving a endpoint compatibility error, so while modifying the Commlib files you will need to do appropriate updates in the firmware as well to make it compatible. Please refer to the Radar Host Communication Library document from /IFX_D2GL-HW-SW_V1.0.0/Firmware_Software/Communication%20Library/ComLib_C_Interface/documentation/html/index.html for more detailed explanation. 

Also the information you want to display will only be possible after making some appropriate changes in the endpoint files.

In case to execute the given Commlib file we would suggest you to refer the following threads on the similar topic: https://community.infineon.com/t5/Radar-sensor/Position2Go-Compile-extract-raw-data-c-example/td-p/2... .

Build and run the C Commlib Interface example code for Position2Go Demo board using the Cmake List file provided in the above thread.

Hope this make things clear!

Best Regards

Honey

Hello @user19 ,

Can you please share the code you have build and also the error log you are getting? 

Meanwhile please refer to the code documentation from Position2Go kit  : /IFX_P2G-HW-SW_V1.0.4/Documentation/FW_API/html/index.html

Best Regards

Honey

Sure I can share my code. I don't get any errors when I run extract_raw_data.c. I use Visual Studio Code and the ComLib C interface.

 

#include <stdio.h>
#include <string.h>
#include "Protocol.h"
#include "COMPort.h"
#include "EndpointRadarBase.h"
#include "EndpointTargetDetection.h"

#define AUTOMATIC_DATA_TRIGER_TIME_US (1000000) // get ADC data each 1ms in automatic trigger mode

}
