Edge Impulse Example: multicore inferencing (Raspberry Pi Pico)

This repository runs an exported impulse on the Raspberry Pi Pico / RP2040. See the documentation at Running your impulse locally. This repository is based on the Edge Impulse Example: stand-alone inferencing (Raspberry Pi Pico).

Requirements

Hardware

Software

Edge Impulse CLI.
GNU ARM Embedded Toolchain.
CMake.

Rasperry Pi Pico SDK:

git clone -b master https://github.com/raspberrypi/pico-sdk.git
cd pico-sdk
git submodule update --init
export PICO_SDK_PATH=`pwd`

Building the application

Get the Edge Impulse SDK

Unzip the deployed C++ library from your Edge Impulse project and copy only the folders to the root directory of this repository:

example-multicore-inferencing-pico/
├─ edge-impulse-sdk/
├─ model-parameters/
├─ source/
├─ tflite-model/
├─ .gitignore
├─ CMakeLists.txt
├─ LICENSE
├─ README.md
└─ pico_sdk_import.cmake

Compile

Create the build folder:
```
mkdir build && cd build
```
Compile:
```
cmake .. && cmake --build . --parallel
```

Flash

Connect the Raspberry Pi Pico to your computer using a micro-USB cable while pressing and holding the BOOTSEL button.

Drag and drop the build/example_multicore.uf2 file to the RPI-RP2 disk in your file explorer.

Serial connection

Use screen or minicom to set up a serial connection over USB. The following UART settings are used: 115200 baud, 8N1.
