做的颜色识别小车，在初始化LCD之后PWM波输出就乱了，没办法正常的驱动电机

qwe1 · 发表于 2021-12-3 19:49:51

在初始化LCD后（  LCD_Init();），PWM的输出就乱了，不能正常的驱动电机运行，把它注释后就正常了
主函数：：
int main(void)
{
vu8 key=0;                //按键值
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);//设置中断优先级
SystemInit();                // 配置系统时钟为72M
uart_init(115200);       //串口初始化
  delay_init();             //延时初始化
  LED_Init();             //板载LED初始化
KEY_Init();             //摁键初始化
Track_Init();             //循迹初始化
  TIM2_PWM_Init(1199,0);    //电机初始化
TIM4_PWM_Init(1199,0);    //电机初始化
SG90_pwm_init();          //舵机初始化
HC_SR04_Init();          //超声波模块初始化
Car_Init();             //小车初始化

// LCD_Init();          //初始化LCD
//将它注释后小车才可以正常运行

LCD_set();                //LCD设置

delay_ms(500);    //延时500ms

while(1)
{
Car_Go();

}

}

void Car_Go(void)
{

TIM_SetCompare1(TIM2 , 1200);//前
  TIM_SetCompare2(TIM2 , 600);
TIM_SetCompare3(TIM2 , 1200);
TIM_SetCompare4(TIM2 , 600);

TIM_SetCompare1(TIM4 , 1200);//后
  TIM_SetCompare2(TIM4 , 600);
TIM_SetCompare3(TIM4 , 1200);
TIM_SetCompare4(TIM4 , 600);

}
