想在stm32單片機(jī)中通過(guò)DHT11傳感器返回的溫濕度自動(dòng)控制繼電器的開(kāi)合，但是代碼好像并沒(méi)有起到控制繼電器的作用，并且運(yùn)行的時(shí)候溫濕度在lcd上沒(méi)有正常顯示，求大神指點(diǎn)如何修改一下代碼，最終可以通過(guò)DHT11檢測(cè)到的溫濕度控制繼電器的開(kāi)合，控制繼電器的代碼如下（）：
GPIO_SetBits(GPIO_jidianqi,jidianqi);
GPIO_ResetBits(GPIO_jidianqi2,jidianqi2);
while(1)
{
if(temp>10&&humi>10)
{
GPIO_SetBits(GPIO_jidianqi,jidianqi);
GPIO_SetBits(GPIO_jidianqi2,jidianqi2);
}
}
主函數(shù)的代碼：
#include "system.h"
#include "SysTick.h"
#include "led.h"
#include "usart.h"
#include "tftlcd.h"
#include "dht11.h"
#include "jidianqi.h"
void data_pros()
{
u8 temp;
u8 humi;
u8 temp_buf[3],humi_buf[3];
DHT11_Read_Data(&temp,&humi);
temp_buf[0]=temp/10+0x30;
temp_buf[1]=temp%10+0x30;
temp_buf[2]='\0';
LCD_ShowString(55,100,tftlcd_data.width,tftlcd_data.height,16,temp_buf);
humi_buf[0]=humi/10+0x30;
humi_buf[1]=humi%10+0x30;
humi_buf[2]='\0';
LCD_ShowString(55,130,tftlcd_data.width,tftlcd_data.height,16,humi_buf);
printf("ζè=%d¡ãC êa¶è=%d%%RH\r\n",temp,humi);
GPIO_SetBits(GPIO_jidianqi,jidianqi);
GPIO_ResetBits(GPIO_jidianqi2,jidianqi2);
while(1)
{
if(temp>10&&humi>10)
{
GPIO_SetBits(GPIO_jidianqi,jidianqi);
GPIO_SetBits(GPIO_jidianqi2,jidianqi2);
}
}
}
