首先从 Arduino官网(https://www.arduino.cc/en/software)下载最新版本的Arduino IDE软件并安装。 安装完成以后,进入首选项(Preferences),找到附加开发板管理器地址(Additional Board Manager URLs),并在其后添加如下信息: http://arduino.esp8266.com/stable/package_esp8266com_index.json ...
②执行以下步骤：在Select Image(选择图像)部分，逐个打开帧文件通过检查图像设置部分检查上传的Image Settings(图像)是否正确如果想要具有黑色背景，并且只点亮线像素，请检查倒置图像颜色,在Background选择Black 在Output（输出部分）在Code output format（代码输出格式）中指定"Arduino code ，single bitmap"在Identifier/...
那么,博主首先立个flag,阅读完本篇博文的最终效果——读者以后在Arduino平台上开发OLED项目的时候,可以考虑U8G2库,并且知道U8G2库的具体用法,甚至可以能够当做工具书来翻阅。 进入正文之前,博主要给读者灌输两个个非常重要的知识点:...
4. 安装库后,重新启动 Arduino IDE。(实测非必须) 再编写代码 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #include<Wire.h>#include<Adafruit_GFX.h>#include<Adafruit_SSD1306.h>#defineSCREEN_WIDTH128// OLED display width, in pixels#defineSCREEN_HEIGHT32// OLED display height, in pixels//...
