1.STM32调试方式

  • 串口调试：通过串口通信，将调试信息发送到电脑端，电脑使用串口助手显示调试信息
  • 显示屏调试：直接将显示屏连接到单片机，将调试信息打印在显示屏上
  • Keil调试模式：借助Keil软件的调试模式，可使用单步运行、设置断点、查看寄存器及变量等功能

2.OLED简介

OLED，即有机发光二极管（ Organic Light Emitting Diode ）。 OLED 由于同时具备自发光，不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异之特性，被认为是下一代的平面显示器新兴应用技术。

LCD 都需要背光，而 OLED 不需要，因为它是自发光的。这样同样的显示 OLED 效果要来得好一些。以目前的技术，OLED 的尺寸还难以大型化，但是分辨率确可以做到很高。在此我们使用的是0.96寸OLED显示屏，该屏有以下特点：

  1. 0.96 寸 OLED 有黄蓝，白，蓝三种颜色可选；其中黄蓝是屏上 1/4 部分为黄光，下 3/4 为蓝；而且是固定区域显示固定颜色，颜色和显示区域均不能修改；白光则为纯白，也就是黑底白字；蓝色则为纯蓝，也就是黑底蓝字。
  2. 分辨率为 128*64
  3. 多种接口方式；OLED 裸屏总共种接口包括：6800、8080 两种并行接口方式、3 线或 4 线的串行 SPI 接口方式、 IIC 接口方式（只需要 2 根线就可以控制 OLED 了！），这五种接口是通过屏上的 BS0~BS2 来配置的。
  4. 本屏开发了两种接口的 Demo 板，接口分别为七针的 SPI/IIC 兼容模块，四针的IIC 模块。两种模块都很方便使用；希望大家根据实际需求来选择不同的模块。

3.模块简介

3.1 I2C模块

  1. GND 电源地
  2. VCC 电源正（3～5.5V）
  3. SCL OLED 的 D0 脚，在 IIC 通信中为时钟管脚
  4. SDA OLED 的 D1 脚，在 IIC 通信中为数据管脚

注：SCL和SDA是I2C的通信引脚 需要接在单片机I2C通信的引脚上 但本次学习中驱动函数模块用的是GPIO口模拟的I2C通信 所以这两个端口可以接在任意的GPIO口上

3.2 SPI模块

  1. GND 电源地
  2. VCC 电源正（3～5.5V）
  3. D0 OLED 的 D0 脚，在 SPI 和 IIC 通信中为时钟管脚
  4. D1 OLED 的 D1 脚，在 SPI 和 IIC 通信中为数据管脚
  5. RES OLED 的 RES#脚，用来复位（低电平复位）
  6. DC OLED 的 D/C#E 脚，数据和命令控制管脚
  7. CS OLED 的 CS#脚，也就是片选管脚

注：除了VCC和GND接电源 剩下的引脚是SPI通信协议的引脚 如果是GPIO口模拟的通信协议 也是可以接在任意的GPIO口上
