PWM wave & nbsp; & nbsp; based on STM32 & nbsp; using TIM2_ CH3 (can be changed by yourself, there is how to change in the notes) the MCU used in the test is stm32f103c8t6. Output PWM wave with TIM2 clock_ CH3 (you can change it by yourself, how to change it in the notes) the output port is pa15, you can also change it by yourself. Code available, main function has the output of PWM wave in the lamp (test), do the breathing lamp, can also change the port output to the motor. After testing, the output PWM is available.
