前言

内容包括：加载英文，汉字，图片，动图效果。

一、显示英文

    ssd1306_Init();
    ssd1306_Fill(Black);
    ssd1306_SetCursor(0, 0);
    ssd1306_DrawString("Hello World!!!", Font_7x10, White);
    ssd1306_UpdateScreen();

这个比较简单就不介绍和展示效果图了。

二、显示汉字

1.详细代码

void SetOledChinese(void)
{
    const uint32_t W = 16;
    uint8_t fonts[][32] = {
     {0x00,0x40,0x20,0x40,0x10,0x40,0x10,0x40,0x00,0x40,0x00,0x40,0xF7,0xFE,0x10,0x40,0x10,0x40,0x10,0x40,0x10,0x40,0x10,0x40,0x14,0x40,0x18,0x40,0x10,0x40,0x00,0x40},/*"计",0*/
     {0x08,0x20,0xFF,0xFE,0x08,0x20,0x7F,0xFE,0x40,0x02,0x8F,0xE4,0x00,0x00,0x7F,0xFC,0x06,0x00,0x3B,0x08,0x04,0xB0,0x19,0xC0,0x62,0xA0,0x0C,0x98,0x72,0x86,0x01,0x00},/*"蒙",1*/
     {0x00,0x00,0x7F,0xFC,0x00,0x80,0x00,0x80,0x01,0x00,0x01,0x00,0x03,0x40,0x05,0x20,0x09,0x10,0x11,0x08,0x21,0x04,0x41,0x04,0x81,0x00,0x01,0x00,0x01,0x00,0x01,0x00},/*"不",2*/
     {0x00,0x80,0x00,0x80,0x79,0x00,0x49,0xFE,0x4A,0x00,0x4C,0x00,0x49,0xF8,0x48,0x08,0x48,0x10,0x48,0x60,0x78,0x80,0x49,0x00,0x02,0x02,0x02,0x02,0x01,0xFE,0x00,0x00},/*"吃",3*/
     {0x04,0x00,0x04,0x00,0x0F,0xE0,0x10,0x20,0x20,0x40,0x7F,0xF8,0xA1,0x08,0x21,0x08,0x3F,0xF8,0x21,0x08,0x21,0x08,0x3F,0xF8,0x00,0x00,0x00,0x00,0xFF,0xFE,0x00,0x00},/*"鱼",4*/
   };
    for (size_t i = 0; i < sizeof(fonts) / sizeof(fonts[0]); i++) {
        ssd1306_DrawRegion(26+i * W, 24, W, fonts[i], sizeof(fonts[0])); 
    };
}

    ssd1306_Init();
    ssd1306_Fill(Black);
    while (1)
    {
       SetOledChinese();
       ssd1306_UpdateScreen();
    }

2.效果图

3.OLED字体取模出现乱码

这款OLED得使用阴码，逐行式，顺向生成字模，如下

三、显示图片

1.图片处理

此OLED为128x64，所以将图片设置为同样大小后，单色位图保存。然后用取模软件取模。

2.详细代码

void SetOledPhoto(void)
{

总结

还可以和很多模块一起搭配使用，本文需要注意的是显示乱码的情况，得使用阴码，逐行式，顺向进行取模。在生活场景中，一些电子阅读器采用OLED屏幕达到更接近纸张的阅读体验。
有什么问题还请私信。

ARM 和 AMD 架构的区别 m0_69576880 arm开发 windows 架构
ARM架构和AMD架构是两种不同的计算机处理器架构，它们有以下几个主要区别：设计出发点、兼容性、性能特点、市场定价。设计出发点：①ARM构架：ARM架构最初是为嵌入式系统设计的，旨在提供低功耗和高效能的解决方案。它主要应用于移动设备、嵌入式系统和物联网设备②AMD架构：AMD架构是基于x86架构的扩展，旨在提供与Intel架构兼容的处理器。它主要用于台式机、服务器和工作站等计算机系统。兼容性：AR
