Pre-requisites Before you can run this demo, make sure you have done the following: 1. Install Rust, with the nightly channel enabled: ```bash # Install via rustup # See https://www.rust-lang.org/tools/install # Enable the nightly channel rustup toolchain install nightly rustup default nightly ``` 2. Install the Zephyr [dependencies](https://docs.zephyrproject.org/latest/develop/getting_started/index.html#install-dependencies); 3. Install [West](https://docs.zephyrproject.org/latest/develop/west/index.html#west) into a virtual environment: ```bash # If Slint source is already checked out: python3 -m venv ../.venv source ../.venv/bin/activate # If you do not have Slint source yet: mkdir slint-zephyr python3 -m venv slint-zephyr/.venv source slint-zephyr/.venv/bin/activate # Install west pip install west ``` 4. Get the Zephyr source code: ```bash # If Slint source is already checked out (this adds the Zephyr source next to the Slint source): cd .. west init -l --mf demos/zephyr-common/west.yaml ./slint # If you do not have Slint source yet (this checks out Slint and Zephyr source into slint-zephyr): west init -m https://github.com/slint-ui/slint --mr zephyr --mf demos/zephyr-common/west.yaml slint-zephyr cd slint-zephyr # Checkout the repositories: west update ``` 5. Export a [Zephyr CMake package](https://docs.zephyrproject.org/latest/build/zephyr_cmake_package.html#cmake-pkg). This allows CMake to automatically load boilerplate code required for building Zephyr applications. ```bash west zephyr-export ``` 6. Zephyr’s scripts/requirements.txt file declares additional Python dependencies. Install them with pip. ```bash pip install -r ~/zephyrproject/zephyr/scripts/requirements.txt ``` 7. [Install the Zephyr SDK](https://docs.zephyrproject.org/latest/develop/getting_started/index.html#install-the-zephyr-sdk) using version [v0.16.8](https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.16.8). ## 2. Hardware This sample has been tested on the [NXP MIMXRT1170-EVKB](https://docs.zephyrproject.org/latest/boards/nxp/mimxrt1170_evk/doc/index.html) with a [RK055HDMIPI4MA0 MIPI display](https://docs.zephyrproject.org/latest/boards/shields/rk055hdmipi4ma0/doc/index.html). The board/debug probe may require configuring as described [here](https://docs.zephyrproject.org/latest/boards/nxp/mimxrt1170_evk/doc/index.html#configuring-a-debug-probe). ```bash # Build west build -b mimxrt1170_evk@B/mimxrt1176/cm7 -p always slint/demos/printerdemo/zephyr -- -DSHIELD=rk055hdmipi4ma0 -DCMAKE_BUILD_TYPE=Release # Flash west flash ``` ## 3. Setup ### 3.1 Build and Run in Simulator Once you have the prerequisites, navigate to this directory and execute the following commands: ```bash # Build west build -b native_sim/native/64 -p always slint/demos/printerdemo/zephyr # Run ./build/zephyr/zephyr.exe ``` The `-p always` option of the build command forces a pristine build. The Zephyr documentation recommends this for new users. ### 3.2 Build and Run on Device This demo has been tested on the [NXP MIMXRT1170-EVKB](https://docs.zephyrproject.org/latest/boards/nxp/mimxrt1170_evk/doc/index.html) with a [RK055HDMIPI4MA0 MIPI display](https://docs.zephyrproject.org/latest/boards/shields/rk055hdmipi4ma0/doc/index.html). The board/debug probe may require configuring as described [here](https://docs.zephyrproject.org/latest/boards/nxp/mimxrt1170_evk/doc/index.html#configuring-a-debug-probe). ```bash # Build west build -b mimxrt1170_evk@B/mimxrt1176/cm7 -p always slint/demos/printerdemo/zephyr -- -DSHIELD=rk055hdmipi4ma0 -DCMAKE_BUILD_TYPE=Release # Flash west flash ``` ## 4.
