 - 初始化MCU的外设时钟,特别是与PWM输出和风扇转速读取相关的GPIO和定时器外设。<br>   - 配置GPIO引脚,将用于PWM输出的引脚设置为输出模式,将用于读取风扇转速的引脚设置为输入模式。<br>2. 配置PWM输出<br>   - 选择合适的定时器用于产生PWM信号。<br>   - 设置定时器的周期,以确定PWM信号的频率,通常4Pin PWM风扇的PWM频率为25kHz。<br>   - 配置PWM占空比,初始可以设置为50%,以启动风扇。<br>   - 启动定时器和PWM输出。<br>3. **读取风扇转速**<br>   - 配置另一个定时器或使用外部中断来检测风扇的TACH(转速)信号。<br>   - 当TACH信号发生变化时,记录时间间隔,以此来计算风扇的转速。<br>   - 由于TACH信号是脉冲信号,通常需要计算一定时间内的脉冲数来得到准确的转速。<br>4. 实现风扇转速控制<br>   - 根据用户输入或系统需求,设定风扇的目标转速。<br>   - 通过闭环控制算法(如PID控制)来调整PWM信号的占空比,以实现目标转速。<br>   - 不断读取实际转速,并与目标转速进行比较,根据误差调整PWM占空比。<br>   - 如果风扇支持温控功能,还可以通过读取温度传感器数据来动态调整风扇转速。<br>以下是这些步骤的文字描述:<br>1. 初始化MCU:<br>   - 配置系统时钟。<br>   - 初始化外设时钟。<br>   - 设置GPIO引脚模式。<br>2. 配置PWM输出:<br>   - 选择并配置定时器。<br>   - 设置PWM频率。<br>   - 设置初始PWM占空比。<br>   - 启动PWM输出。<br>3. 读取风扇转速:<br>   - 配置定时器或外部中断。<br>   - 检测TACH信号变化。<br>   - 计算转速。<br>4. 实现风扇转速控制:<br>   - 设定目标转速。<br>   - 使用控制算法调整PWM占空比。<br>   - 比较实际转速与目标转速。<br>   - 根据需要调整风扇转速。</p> <p class="paragraph
