Running Edge Impulse on nRF52840 in a custom board.

[mr_thomas]

I am trying to deploy an trained Impulse module into nRF52840, but not sure about how to do it.

In the edge impulse documentation, they mention we can link the impulse from any c application, by compiling the impulse as a shared library and link to it from a C application.

So as per instructions I have built the impulse as a shared library and have produced an shared library file (.so file).

What I need help with is linking it to my nRF application. I have no clue on how to do it.

I looked into a default blink example in the nrf-sdk built using armgcc with a makefile, in hope to include the impulse shared library in it and build an application, but to be frank the makefile written in the nrf-sdk is quite difficult for me to follow.

Please can anyone help me and point me in the right direction on how to including the shared library '.so' file with any default application in the nrf-sdk.

Hey! I did try this.

But I get this error:

CMake Error: The source directory "D:/Kshitij/v1.6.1/nrf/samples/edge_impulse/wrapper/build_nrf52840dk_nrf52840/-EI_API_KEY_HEADER=x-api-key:xxxxxxx<my-apikey>xxxxxxx" does not exist.

I did follow the documentation line by line and did as instructed.
