例程描述

这个例程展示了如何配置TIM1外设来生成6步输出。
系统时钟工作在96Mhz，通过PLL配置产生。PLL时钟源是外部8Mhz晶振。APB1的分频比是1，APB2的分频比是1。
TIM1外设可以预先编程下一个TIM1输出行为的配置（步骤），当COM使用（换向）事件，同时更改所有通道的配置。
COM时间可以通过设置TIM1_EGR COM bit 来软件生成或者由硬件的TRC rising edge。
在这个例程中，软件COM EVENT 通过滴答定时器中断每100ms生成1次。
Break极性设置为高。
下面表格描述了TIM1 channel的状态:

硬件和软件环境

硬件平台搭建
- HSE 连接外部8MHz晶振
- 将TIM1引脚连接到示波器上，以监测不同的波形:
  - TIM1_CH1 pin (PA8)
  - TIM1_CH1N pin (PB13)
  - TIM1_CH2 pin (PA9)
  - TIM1_CH2N pin (PB14)
  - TIM1_CH3 pin (PA10)
  - TIM1_CH3N pin (PB15)
- 连接 TIM1 break pin TIM1_BKIN pin (PB12) to the VCC 来生成Break。

如何使用？

为了使程序工作，您必须执行以下操作 :

使用 MDK5 打开此例程文件夹中的 TIM_6Steps.uvprojx 工程
重新编译该工程并下载到目标存储器中
