1. Function description
     1. TIM1 uses the update interrupt to generate timing rollover IO
2. Use environment
     Software development environment: KEIL MDK-ARM V5.34.0.0
     Hardware environment:  N32G003F5S7-STB V1.0
3. Instructions for use
     System Configuration;
         1. Clock source:
                     AHB=48M,APB=48M,TIM1 CLK=APB
         2. Interruption:
                     TIM1 update interrupt is turned on, priority level 1
         3. Port configuration:
                     PA6 is selected as IO output
         4. TIM:
                     TIM1 enables periodic interrupts
	       
     Instructions:
         1. Download and run after compilation
         2. Flip PA6 in the cycle interrupt of TIM1, and the waveform can be viewed through an oscilloscope or logic analyzer
4. Matters needing attention
     None
