str91x dth90 sht1x传感器驱动.doc

因为电路没有粘上，所以在这里说明一下，使用的是str911faw42芯片，用了uart0,uart1两个串口。Arm芯片的没有所谓的通用io口，在接传感器的时候，p2.1、p2.7接到sht1x的data口，p2.0接到它的clk口，注意上拉电阻10k；显示模块与p6.1-p6.5相连，lcd的型号也不太清楚，下面简单说了一下。其他一些注释请看程序。Ps：我的程序使用了zigbee模块，程序的uart1写入的数组是用来设置它的，uart0则是用来调试的。主函数#include #include 91x_lib.h#include LCD_TFT.h#include dth90.h#include dsphzi.h#define DATA1 GPIO_ReadBit(GPIO2,GPIO_Pin_7)GPIO_InitTypeDef GPIO_InitStructure;UART_InitTypeDef UART_InitStructure;RTC_TIME time;RTC_DATE date;RTC_ALARM alarm;void Init_RTC_VIC(void);void DelayLong(u16 Num);void Init_config(void);void sensor_send(u8 *ss_data);void start_display(void);void Display_factor(u8 sensorflag);void Display_clear(u8 sensorflag1);void Sensordata(void);
