This is a draft playground repository to check opencv capabilities with zephyr rtos in embedded world

Currently it is only tested with stm32u5xx boards, as it takes ~3mb of rom/flash

For a fresh start

• Clone this repo
• git submodule init --update
• west init -l u5
• west update
• west build -b stm32u5g9j_dk2 u5/app/ -- -DBOARD_ROOT=./../ (builds for stm32u5g9j_dk2 board, you can google what that board is)
• west flash

Important note: since stm32u5g9j_dk2 doesn't have camera sensor, you need to find out your own way how to transfer images to the board; I used uart for that purpose

To enable OpenCV library and example code

• in u5/app/prj.conf : CONFIG_OPENCV_LIB=y

Note: there are maybe more dependencies, so watch out

Also possible to use tflite micro

• in u5/app/prj.conf : CONFIG_TFLITE_LIB=y

Planning to add support for stm32n6 boards

there are more custom boards based on stm32u5xx family, PCB repository is coming

If you are willing to roll out your own board, please don't hesitate to contact me

Note: this project is in it's very very early phase
