電調(diào)驅(qū)動(dòng)無(wú)刷電機(jī)兩路PWM
單片機(jī)源程序如下:
- #include "led.h"
- #include "delay.h"
- #include "key.h"
- #include "sys.h"
- #include "usart.h"
- #include "timer.h"
-
- int main(void)
- {
- u16 led0pwmval1,led0pwmval2;
- delay_init(); //延時(shí)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(jí)，2位響應(yīng)優(yōu)先級(jí)
- uart_init(115200); //串口初始化為115200
- LED_Init(); //LED端口初始化
- TIM3_PWM_Init(1999,719); //
-
-
-
- led0pwmval1=200;
- led0pwmval2=200;
- TIM_SetCompare1(TIM3,led0pwmval1);
- TIM_SetCompare2(TIM3,led0pwmval2);
- delay_ms(1000);
- led0pwmval1=100;
- led0pwmval2=100;
- TIM_SetCompare1(TIM3,led0pwmval1);
- TIM_SetCompare2(TIM3,led0pwmval2);
- delay_ms(1000);
- led0pwmval1=105;
- led0pwmval2=105;
- TIM_SetCompare1(TIM3,led0pwmval1);
- TIM_SetCompare2(TIM3,led0pwmval2);
- }
