I set the parameter of TIM5 of my MCU on CubeMX,the frequency of the clock is 72 MHz,PSC is 7199,ARR is 199,the information about my settings is below: TIM5 is used to output 4 channels of PWM to control four SG90 servos,TIM1 toTIM4 is used to contr...

These are relevent programs I wrote,can you help me find the problems in it?I wonder where the problems come from.I want the servo turn to 0 degree at first,turn to 90 degrees when I press these keys.Thank you very much!

PWM frequency=(ARR+1)*(PSC+1)/72MHz=0.2s=20ms,if I want to make four sevros turn to 0 degree,I should give it a high level for 0.5ms,so0.5/20*200=5, I think my PWM setting is okay.Can you provide me another suggestion?Thank you very much!!
