前言

前不久加入了一个大佬创立的星闪的社区，私下交流中，了解到星闪协议的一些内容，看了大佬关于OLED的demo，感觉描述的还是不够细节，跳过了许多步骤，容易造成误解，不适合小白，我作为一个小白，深知入门开发的细节一笔带过可能需要尝试很多次才能成功，而且使用oled屏幕的demo打印信息、便于调试，调试oled屏幕是开发过程中十分重要的能力，所以今天写一篇关于OLED灯保姆级别教程。
社区如下：星闪开发社区，加入可能需要审核。

一、图像处理

由于oled屏幕的大小是128*64像素、单色显示，所以需要预先处理一下图像，否则会出现显示不全、取模软件无法识别图像等问题。

具体处理细节如下：（计蒙哥直接一笔带过，问大佬要了一些星闪技术资料）

因为oled屏幕的屏幕大小为128*64像素。

点击另存为（不要选择其他格式，具体格式如下）

单色位图能够被取模软件识别，并成功取模。

二、图像取模

使用取模软件对处理完的图片取模处理，具体处理步骤如下：

这里要注意设置正确，否则字模乱码，无法实现图像显示。

三、关键代码【Hispark Studio】—— IDE

将TXT文件中的字模复制到以下函数中替换，注意{}括号 ;分号的个数，否则会编译失败。

   }};
   ssd1306_DrawBitmap(photo[0],sizeof(photo));
    

}

    while(1){
        ssd1306_SetCursor(0, 0);
        picture();
    // ssd1306_DrawString("just do it", Font_7x10, White);
        ssd1306_UpdateScreen();
        }

四、配置代码

编辑fbb_ws63-master\src\application目录下CMakeLists.txt 、Kconfig文件

首先编辑CMakeLists.txt。

在文件最后部分但不是最后一行添加，代码如下：

if(DEFINED CONFIG_SAMPLE_SUPPORT_OLED)
    add_subdirectory_if_exist(oled)
endif()

注意：
要写在set(SOURCES "${SOURCES}" PARENT_SCOPE) 代码行以上
add_subdirectory_if_exist(oled) 的 (oled)为 fbb_ws63-master\src\application目录下的文件夹名称

---

代码如下：

config SAMPLE_SUPPORT_OLED
    bool
    prompt "Support OLED Sample."
    default n
    depends on ENABLE_PERIPHERAL_SAMPLE
    help
        This option means support OLED Sample.

注意：OLED的名称一致。
