* `fetch-cube` ([examples/fetch-cube](examples/fetch-cube)) - example of using FetchContent for fetching STM32Cube from ST's git.
* `fetch-cmsis-hal` ([examples/fetch-cmsis-hal](examples/fetch-cmsis-hal)) - example of using FetchContent for fetching STM32 CMSIS and HAL from ST's git.
* `blinky` ([examples/blinky](examples/blinky)) - blink led using STM32 HAL library and SysTick.
It will compile a project for the `F4` family by default, but you can also compile for the
`L0` and `F1` family by passing `L0_EXAMPLE=ON` or `F1_EXAMPLE=ON` to the CMake generation call.
* `freertos` ([examples/freertos](examples/freertos)) - blink led using STM32 HAL library and FreeRTOS.
