# Blinky Example

This example demonstrates the integration of FreeRTOS's kernel and MCU-Driver-HAL into a simple
application.

This example supports the following targets:

- Cortex-M55: `ARM_AN552_MPS3`
- Cortex-M4: `ARM_AN386_MPS2`

## Building

```sh
# Note: This requires `arm-none-eabi-gcc` and `ninja` commands to be available on the path
cmake -B __build -GNinja --toolchain=toolchains/toolchain-arm-none-eabi-gcc.cmake -DCMAKE_SYSTEM_PROCESSOR=cortex-m4 -DMDH_PLATFORM=ARM_AN386_MPS2 .
cmake --build __build -j
```

## Running

The application can be ran using the following command:

```sh
VHT_MPS2_Cortex-M4 blinky
```

Note that due to how the model optimises the execution, you may need to add `--parameter armcortexm4ct.scheduler_mode=1`
in order to get more accurate frequency of the interrupt generation.

## Known limitations

The armclang toolchain is not yet fully supported.
