基于STM32单片机定时器主从方式输出可控个数的PWM脉冲的KEIL工程源码， int main(void) { u32 i=0; NVIC_Config(); GPIO_Config(); TIM2_Master__TIM3_Slave_Configuration(10); // ÅäÖÃTIM2µÄÂö³åÊä³öΪ10Hz while(1) { if(TIM2_Pulse_TIM3_Counter_OK == 0) Output_Pulse(10); else if(TIM2_Pulse_TIM3_Counter_OK == 2) { for(i=0; i<10000000; i++); // Delay TIM2_Pulse_TIM3_Counter_OK = 0; } } }
