Debugging my code using edge impulse on vs code

[gizgiz]

I wat to deug my coe and I have this errors, have you an idea about how to fix them?

Hi,

For context, see our nRF Connect SDK and nRF5 SDK statement.

From your log file, it looks like you are using the nRF5 SDK for this.

To use Edge impulse, I strongly recommend that you use our nRF Connect SDK instead.
This SDK has multiple samples for Edge Impulse, such as:

nRF Machine Learning

Edge Impulse samples

To debug using the nRF Connect SDK with VS Code, see this youtube tutorial.

But I couldn't find many library that I want to work with them and I have already a code written with nrf5sdk that I want to add artificial intelligence to it " I spend a lot of months working on it"

Hi,

In that case, I will try to help you. But I can not guarantee how much I can do.

First qustion:

Does the code work when you do not debug?
(Or do you get another behaviour?)

I can build my code, and when I debug The code stopped and didn't give me the result of this function

if (process_input(500)>0.5)

   SEGGER_RTT_WriteString(0, "in danger");

   else

   SEGGER_RTT_WriteString(0, "not in danger");

<<<float process_input(uint8_t val){

  features[0]=val;

  for (i=1;i<600;i++)

  features[i]=0;

  signal_t signal;

  signal.total_length=FEATURES_SIZE;

  signal.get_data=&raw_feature_get_data;

  ei_impulse_result_t result;

  EI_IMPULSE_ERROR res = run_classifier(&signal,&result,true);

 return result.classification[0].value;
