此为小车源程序，刚刚起步，等以后学会更多，上传更新的版本。
单片机源程序如下:
- #include "beep.h"
- #include "delay.h"
- #include "key.h"
- #include "led.h"
- #include "usart.h"
- #include "exit.h"
- #include "sys.h"
- #include "timer.h"
- int main(void)
- {
- u16 dianji1=0;
- u16 dianji2=0;
- delay_init(); //延时函数初始化
- NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //设置NVIC中断分组2:2位抢占优先级，2位响应优先级
- // EXTI4_Init();
- // uart_init(115200); //串口初始化为115200
- // LED_Init(); //LED端口初始化
- // TIM3_PWM_Init(899,0); //不分频。PWM频率=72000000/900=80Khz
- TIM2_PWM1(899,0);
- TIM2_PWM2(899,0);
- IN_Init();
- while(1)
- {
- pa5=pa8=1;
- pa6=pa7=0;
- delay_ms(10);
- dianji1=720;
- dianji2=720;
- TIM_SetCompare3(TIM2,dianji1);
- TIM_SetCompare4(TIM2,dianji2);
- }
- }
