计时器外设
使用计时器外设（例如 STM32 处理器提供的编码器、更高分辨率计时器、PWM、计时器、计时器捕获及更多）创建 Simulink® 模型。使用模型配置参数配置 Simulink 模型以与支持的目标硬件对接。
要支持在基于 STM32 处理器的板上运行 Simulink 模型，需要使用 STM32CubeMX 图形化工具。STM32CubeMX 工具采用图形界面，可用于配置 STM32 处理器的外设，并为所选的 STM32 处理器生成外设初始化代码。您可以配置基于 STM32 处理器的板，以将 STM32CubeMX 工程与 Simulink 结合使用来生成代码并将代码部署到硬件。
