温度传感器SHT1x和SHT2x的iic通信代码，这都是从网上找的代码，sht1x亲测可用，sht2x时序也是准确的。后续将呈现sht7x代码
单片机源程序如下:
- #include "led.h"
- #include "delay.h"
- #include "sys.h"
- #include "usart.h"
- #include "lcd.h"
- #include "SHT10.h"
- SHT1x sht1x; //定义传感器结构体
- int main(void)
- {
- u8 t=0,error=0,checksum,value=0;
- volatile u8 T_Display=0,H_Display=0;
- u16 T_Value=0,H_Value=0;
- delay_init(); //延时函数初始化
- uart_init(9600); //USART1初始化
- LED_Init(); //LED初始化
- LCD_Init();
- SHT1x_Init();
-
- POINT_COLOR=RED;//设置字体为红色
- LCD_ShowString(60,120,200,16,16,"SHT1X Test");
- POINT_COLOR=BLUE;//设置字体为蓝色
- LCD_ShowString(60,150,200,16,16,"Temp: . C");

-

- {

- {

- {

- else SHT1X_softreset();
- }
- }
- }
- while(1)
- {
- //------------------------读取SHT1X传感器数据--------------------------------------
- error+=SHT1x_Measure( &T_Value,&checksum,0); //measure temperature

-

- }

- }

-

- {
