基于msp430f169的蓝牙风扇可调速程序

ID:610137 · 发表于 2019-9-10 18:20

设计做的，比较简单，手机通过UART连接单片机，PWM可任意调速，注意风扇的驱动电压。
#include <msp430f169.h>
#include "lcd12864.h"
#include "PWM.h"
#include "UART.h"
#include "adc.h"

unsigned char key = 0;
unsigned char Statu = 0;
unsigned int a = 0;

#pragma vector=USART0RX_VECTOR
__interrupt void USART0_RX_ISR(void)
{
  unsigned char data=0;
  data=U0RXBUF;                      //接收到的数据存起来
  key = data;
  Uart0Send_Byte(data);             //将接收到的数据再发送出去

}

void main(void)
{
WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer
Clock_Init(1);             // 0 就是 1M， 1 就是 8M
PWM_init();                // Init the PWM
Port_init();             // Init the LCD1602
LCD_init();
UART0_Init();
LCD_Desk();
ADC_Init();
_BIS_SR(GIE);                                     //开启系统中断
while(1){
      LCD_Desk();
      ADC();
      LCD_DisplayTemp((uchar)TemperC);
      delay_ms(500);
      _NOP();
      switch(key){
      case 49:start(); LCD_write_str(4,2,"1"); LCD_write_str(4,1,"ON ");break;
      case 50:speed(1);LCD_Display_num(4,2,2);LCD_write_str(4,1,"ON ");break;
      case 51:speed(2);LCD_Display_num(4,2,3);LCD_write_str(4,1,"ON ");break;
      case 52:speed(3);LCD_Display_num(4,2,4);LCD_write_str(4,1,"ON ");break;
      case 48:stop();  LCD_write_str(4,2,"0");LCD_write_str(4,1,"OFF");break;
      default:break;
      }
      key=0;
}
