標(biāo)題: arduino oled+dht11顯示
在網(wǎng)上找了很久，都沒(méi)有找到有關(guān)的資料。就自己改了程序[attach]92884[/attach]庫(kù)文件什么的都在壓縮包了
#include <Arduino.h>
#include <U8g2lib.h>
#include <dht11.h>
dht11 DHT11;
#define DHT11PIN D6  //可改接口，這是我D1開(kāi)發(fā)板的
#ifdef U8X8_HAVE_HW_SPI
#include <SPI.h>
#endif
#ifdef U8X8_HAVE_HW_I2C
#include <Wire.h>
#endif
U8G2_SSD1306_128X64_NONAME_F_SW_I2C u8g2(U8G2_R0, /* clock=*/ D3, /* data=*/ D4, /* reset=*/ U8X8_PIN_NONE); // ESP32 Thing, pure SW emulated I2C
void setup(void) {
  Serial.begin(9600);
  u8g2.begin();
  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.print("Temperature (oC): ");
  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.setCursor(0, 28);
  u8g2.print((float)DHT11.humidity, 2);
  u8g2.setCursor(0, 40);
  u8g2.print("Temperature (oC): ");    // Chinese "Hello World"
u8g2.setCursor(0, 60);
  u8g2.print((float)DHT11.temperature, 2);    // Chinese "Hello World"
  u8g2.sendBuffer();

  delay(1000);
}

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

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