nrf_axon_nn_model_1st_external_input_ndx()

int8_t nrf_axon_nn_model_1st_external_input_ndx

(

const nrf_axon_nn_compiled_model_s *

the_model

)

returns the nrf_axon_nn_compiled_model_input_s instance of the model's input that is external.

The 1st layer in a model can have multiple inputs; one that is internal (ie, VarHandle for streaming models), and 1 that is external. This will find which input needs to be populated explicitly before inference begins.

Parameters

[in]

the_model

Model to find the external input for.

Return values

index

into the_model->inputs[] for the model's external input.
