歡迎交流學(xué)習(xí)
電路原理圖如下：
單片機(jī)源程序如下:

- #include "key.h"
- #include "sys.h"

- int main(void)
- {

- float Speed = 0,Speed2 = 0;
- PID_init();
- PID2_init();

- //設(shè)置中斷優(yōu)先級分組為組2：2位搶占優(yōu)先級，2位響應(yīng)優(yōu)先級
- //LED_Init(); //LED端口初始化
- Adc_Init(); //ADC初始化
- TIM1_PWM_Init(999,71); //不分頻。PWM頻率=72000000/9000=8Khz

- while(1)
- {
-
