#单片机

本文探讨了物联网设备的连接方式，包括使用Adafruit GFX库进行显示和Wire、SPI通信协议的使用。同时展示了如何通过编程实现设备连接，并分析了不同天气条件下的图像图标，如多云、下雨、太阳等。

提示：文章写完后，目录可以自动生成，如何生成可参考右边的帮助文档

一、实物连接

示例：pandas 是基于NumPy 的一种工具，该工具是为了解决数据分析任务而创建的。

二、代码实现

//#include <Adafruit_GFX(1).h>















#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include <SPI.h>

#include "bitmap.h"
//#include "sensorManage.h"

#define uint8  unsigned char
#define uint16 unsigned int

#define OLED_RESET 8
Adafruit_SSD1306 display(OLED_RESET);

//constant define
#define PICTURE_GLCD_HEIGHT 64 
#define PICTURE_GLCD_WIDTH  128
#define BAR_Y 20
#define BAR_X 57
#define BAR_WIDTH 50

//pin define
#define photoPin A0

void setup()   
{
   
     
    //----- by default, we'll generate the high voltage from the 3.3v line internally! (neat!)
    display.begin(SSD1306_SWITCHCAPVCC, 0x3c);  // initialize with the I2C addr 0x3D (for the 128x64)
    display.clearDisplay();
}

void loop()
{
   
   
    //showLight();
    showLogo(0, 0);
}

void showLogo(uint8 x, uint8 y)
{
   
   
    display.clearDisplay();   // clears the screen and buffer
    display.drawBitmap(x, y,  logo_CLB, PICTURE_GLCD_WIDTH, PICTURE_GLCD_HEIGHT, 1);
    display.display();
}
