概要
使用LED2,pwm模拟电压变化控制呼吸变化
开源口碑分享内容

PB10的复用功能映射到LPTIM_CH1,官方例程有该程序,对该程序进行修改

（关于官方例程的使用体验

功能清晰易懂，各功能区块分装结构条例清晰，例程能够帮助用户快速理解和移植项目掌握

低功耗表现良好：在使用例程时，LPTIM\_CH1在STOP4模式下，测试功耗大概在6uA左右，这对于需要低功耗设计的项目来说是非常有帮助的。）

lptim_pwm_output.h中需要声明引用函数




（在项目可移植性方面，MM32F5333的LPTIM_CH1官方库例程的体验如下：

优势

       标准的库函数结构：例程遵循MM32标准库的函数结构和命名规范，使得代码在不同MM32系列单片机之间具有较好的通用性和可移植性。例如，若在另一个MM32单片机上也要使用LPTIM功能，只需根据新单片机的LPTIM特性稍作配置，大部分的函数调用和逻辑结构都可以直接复用，减少了重复开发的工作量。

       抽象的硬件操作接口：通过库函数提供了抽象的硬件操作接口，将底层硬件寄存器的具体操作细节封装起来。在移植到其他MM32单片机时，只要硬件资源支持LPTIM功能，且库函数也适用于新单片机，就可以直接使用这些接口来操作LPTIM，无需深入了解每个单片机的硬件寄存器差异，使得代码的移植更加便捷高效。

       不同芯片资源差异的适配：虽然MM32系列单片机的LPTIM功能在原理上有一定相似性，但不同型号在具体资源如时钟源选择、中断优先级配置等方面可能存在细微差别。在移植时，针对这些差异需要仔细调整和适配，否则可能会出现功能不正常或者性能不达标的情况。例如，某些单片机可能支持的时钟源与当前例程所使用的时钟源不同，需要根据目标单片机的时钟树重新配置时钟源，以确保LPTIM的时钟输入符合要求。
