arduino oled+dht11显示

在网上找了很久，都没有找到有关的资料。就自己改了程序库文件什么的都在压缩包了
#include< Arduino.h>
#include< U8g2lib.h>

dht11 DHT11;
#define DHT11PIN D6  //可改接口，这是我D1开发板的

   u8g2.enableUTF8Print();     // enable UTF8 support for the Arduino print() function  
}  

void loop(void) {  
   int chk = DHT11.read(DHT11PIN);
   Serial.print("Humidity (%): ");
   Serial.println((float)DHT11.humidity, 2);

   Serial.println((float)DHT11.temperature, 2);
delay(2000);
   u8g2.setFont(u8g2_font_unifont_t_chinese2);  // use chinese2 for all the glyphs of "你好世界"  
   u8g2.setFontDirection(0);  
   u8g2.clearBuffer();  
   u8g2.setCursor(0, 15);  
   u8g2.print("Humidity (%):");

   u8g2.print((float)DHT11.humidity, 2);  
   u8g2.setCursor(0, 40);

   u8g2.sendBuffer();

request for member 'read' in 'DHT11', which is of non-class type 'const uint8_t' {aka 'const unsigned char'}
