Build

Preparations

git clone https://github.com/jomjol/AI-on-the-edge-device.git
cd AI-on-the-edge-device
git checkout rolling
git submodule update --init

Update Submodules

cd /components/submodule-name (e.g. tflite-micro-example)
git checkout VERSION (e.g. HASH of latest tflite-micro-example build)
cd ../../ (auf Ebene von code)
git submodule update --init

Evt. muss man vorher noch einige Verzeichnisse in compenents von Hand löschen, da sie beim checkout nicht gelöscht wurden (vor update -- init)

Build and Flash within terminal

See further down to build it within an IDE.

Compile

cd code
platformio run --environment esp32cam

Upload

pio run --target upload --upload-port /dev/ttyUSB0

Alternatively you also can set the UART device in platformio.ini, eg. upload_port = /dev/ttyUSB0

Monitor UART Log

pio device monitor -p /dev/ttyUSB0

Build and Flash with Visual Code IDE

  • Download and install VS Code

  • Install the VS Code platform io plugin

    • Check for error messages, maybe you need to manually add some python libraries
      • e.g. in my Ubuntu a python3-env was missing: sudo apt-get install python3-venv

  • git clone this project

    • in Linux:

      git clone https://github.com/jomjol/AI-on-the-edge-device.git
cd AI-on-the-edge-device
git checkout rolling
git submodule update --init

  • in VS code, open the AI-on-the-edge-device/code

    • from terminal: cd AI-on-the-edge-device/code && code .

  • open a pio terminal (click on the terminal sign in the bottom menu bar)

  • make sure you are in the code directory

  • To build, type platformio run --environment esp32cam

    • or use the graphical interface:
    • the build artifacts are stored in code/.pio/build/esp32cam/

  • Connect the device and type pio device monitor. There you will see your device and can copy the name to the next instruction

  • Add upload_port = you_device_port to the platformio.ini file

  • make sure an sd card with the contents of the sd_card folder is inserted and you have changed the wifi details

  • pio run --target erase to erase the flash

  • pio run --target upload this will upload the bootloader.bin, partitions.bin,firmware.bin from the code/.pio/build/esp32cam/ folder.

  • pio device monitor to observe the logs via uart
