描述

PWM Output 模块在指定输出引脚上生成方形波形。模块输入控制方形波形的占空比。您可以提供介于 0 - 100 之间的值作为模块输入。输入值 0 产生 0% 占空比，输入值 100 产生 100% 占空比

输入

有效输入值的范围是 0 - –100。输入控制方形波形的占空比（方波的宽度）。

输入值 0 产生 0% 占空比，输入值 100 产生 100% 占空比。任何超出范围的值，例如 500 或 -500，在模块输入端口上具有与最大或最小输入值相同的效果。

数据类型: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32

要查看板上的引脚映射，请点击查看引脚映射。

确保为模型中的不同模块分配不同引脚名称。

除了引脚映射表中提到的引脚名称外，还有其他备用引脚名称 (Px_y_ALTz)，可用于访问连接到同一引脚的其他硬件外围设备。要了解详细信息，请参考Usage of Alternate Pin Names。

备用引脚名称仅适用于 Simulink® Coder™ Support Package for STMicroelectronics® Nucleo Boards and Discovery boards。

指定 PWM 波形的初始频率。

指定介于 0 - 100 之间的初始占空比。
