stm32正交編碼器
單片機(jī)源程序如下:
- #include "STM32F1.h"
- u16 Parameter = 400; //輸入編碼器線數(shù)
- u16 Count,Old_Count;
- int main(void)
- {
- 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，2位響應(yīng)優(yōu)先級
- uart_init(115200); //串口初始化為115200
- LCD_Init(); //初始化LCD
- TIM_Init(); //初始化TIM4為編碼器借口模式
- POINT_COLOR=BLUE; //字體顏色
- LCD_ShowString(75,150,200,16,16,"Count:");
- LCD_ShowNum(125,150,0,1,16);
- LCD_ShowNum(135,150,0,1,16);
- LCD_ShowNum(145,150,0,1,16);
- LCD_ShowNum(155,150,0,1,16);
- while(1)
- {
- Old_Count = Count; //獲取先前的計(jì)數(shù)值
- Count = TIM4->CNT;
- printf("數(shù)值"); //獲取編碼器當(dāng)前數(shù)值
- if(Old_Count != Count) //如果先前的計(jì)數(shù)值與當(dāng)前計(jì)數(shù)值不相等，說明編碼器已轉(zhuǎn)動打印當(dāng)前數(shù)值
- {
- printf("數(shù)值 = %d\n",Count); //串口打印數(shù)值
- LCD_ShowNum(125,150,Count/1000,1,16); //液晶顯示數(shù)值
- LCD_ShowNum(135,150,(Count%1000)/100,1,16);
- LCD_ShowNum(145,150,(Count%100)/10,1,16);
- LCD_ShowNum(155,150,Count%10,1,16);
- }
- }
- }
