    使用方法：
        1、编译后打开调试模式，用示波器或者逻辑分析仪观察TIM1的波形
        2、PA2拉低可观察到4对互补PWM，PA2拉高PWM消失


1. Function description

    1. TIM1 outputs 4 complementary waveforms
    
2. Development environment

    Software development environment:KEIL MDK-ARM 5.34
                                    IAR EWARM 8.50.1
    Hardware development environment:
        N32G033 series:
            Developed based on the evaluation board N32G033K8Q7-1_STB V1.0
3. How to use
    System Configuration;
        1. Clock source: HSI+PLL
        2. Clock frequency: 
            N32G033 series:
                SYS_CLK=64M,TIM1_CLK=64M        
        3. Port configuration:
            PA4 is selected as TIM1 CH1 output
            PA3 is selected as TIM1 CH2 output
            PA5 is selected as TIM1 CH3 output
            PB3 is selected as TIM1 CH4 output
            PA7 is selected as TIM1 CH1N output
            PB4 is selected as TIM1 CH2N output
            PB5 is selected as TIM1 CH3N output
            PB6 is selected as TIM1 CH4N output
            PA2 is selected as break input
        4. TIM:
            TIM1 4-pair complementary with dead zone, PA2 is brake input
    Instructions:
        1. After compiling, turn on the debug mode, and use an oscilloscope or logic analyzer to observe the waveform of TIM1
        2. When PA2 is low, 4 complementary PWM can be observed, and when PA2 is high, PWM disappears
4. Attention
