stm32步進(jìn)電機(jī)驅(qū)動源程序如下:

//#include "timer.h"
int main(void)
{
delay_init(); //延時函數(shù)初始化
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //設(shè)置NVIC中斷分組2:2位搶占優(yōu)先級，2位響應(yīng)優(yōu)先級
uart_init(115200); //串口初始化為115200
LED_Init(); //LED端口初始化
LED0=0;
TIM3_CH1_init();
delay_ms(200);
while(1)
{
LED0=1;
TIM2_TIM3_PWM(2000, 12); //每次少10個脈沖
delay_ms(200);
LED0=0;
TIM2_TIM3_PWM(2000, 25); //每次少10個脈沖
delay_ms(250);
LED0=1;

delay_ms(100);
LED0=0;
TIM2_TIM3_PWM(2000, 35); //每次少10個脈沖
delay_ms(150);
}
}
