【功率监测与控制系统DIY活动过程贴】OLED显示
本文介绍了基于 NUCLEO-F411RE 开发板、使用 SMT32CubeMX 软件快速生成工程，实现了通过硬件 I2C1 实现 4 线 OLED 屏显示数字、字符、字符串、汉字的项目设计，包括原理介绍、硬件连接、汉字取模、代码解析等流程。
项目方案
该项目通过 STM32CubeMX 构建 IIC 驱动的基本工程框架，使能 IIC ，之后在 oled.c 文件中定义相关显示函数，包括字符串、文字、数字等，在主函数中调用显示函数，实现 OLED 驱动与目标字符现实。
OLED
OLED（有机发光二极管）是一种自发光显示技术，不需要背光源，具有高对比度、薄厚度、广视角和快速响应等优点。OLED显示模块通常由OLED屏幕和驱动芯片组成，常见的驱动芯片是SSD1306
SSD1306 是一个单片 CMOS OLED/PLED 驱动芯片，支持 128x64 点阵显示。它内置了对比度控制器、显示 RAM和晶振，支持多种接口方式，包括 6800/8000 串口、I2C 接口和 SPI 接口。
显示原理
OLED 显示屏通过 SSD1306 驱动芯片控制，SSD1306 将显存分为 8 页，每页包含128个字节，总共128x64位。显示数据通过并行或串行接口传输到SSD1306，由 SSD1306 控制 OLED 屏幕显示。
详见：OLED显示模块（原理讲解、STM32实例操作） .
OLED显示
介绍了实现OLED屏幕显示信息的项目流程。
打开 STM32CubeMX 软件，新建 ST 板卡工程；
时钟配置：采用默认设置，系统时钟频率 84MHz；
Pinout & Configuration 标签下选择 Connectivity - I2C1 , 右侧 Mode 选择 I2C 使能 IIC 总线功能，此时 Pinout View 中 IIC 对应的管脚被标注为 I2C1 ；
配置完成后，进入 Project Manager 标签栏，进行项目命名、保存路径设置、编译器选择等操作；
点击 Generate Code 按钮，使用 STM32CubeIDE 或 Keil 打开目标工程；
编译工程，0 error, 0 warning .
硬件连接
PB7 ---- SDA (OLED)
PB6 ---- SCL (OLED)
NUCLEO-F411RE 排针布局和定义
汉字取模
下载 并运行 PC2LCD2018 软件 ；
菜单栏模式设置为 字符模式 ；
点击工具栏中的 设置 按钮，配置字模选项：列行式取模、低位在前等，设置完成后点击 确定 保存配置；
在文字输入选框输入目标汉字，点击 生成字模 ；
选中复制或保存字模，代码添加至 oledfont.h 文件。
参考：驱动0.96寸OLED显示屏 、STM32CubeMx+0.96寸OLED（IIC驱动）
代码
在 .../Core/Inc 文件夹新建 oled.h 和 oledfont.h 头文件，
在 .../Src 文件夹新建 oled.c 文件，并在 main.c 中调用相关函数，实现功率计的框架显示
代码分别如下
