OLED简介

LED，即有机发光二极管（Organic Light-Emitting Diode），又称为有机激光显示（Organic Electroluminesence Display）。
OLED显示屏就是利用有机发光二极管制成的显示屏，只要在正负极上加上正确的电压就会发光。

这次我们学习的就是市面上常见的0.96寸OLED屏幕，黄蓝屏，上1/4为黄色，下3/4为蓝色。使用的是SPI通信，分辨率为128*64。

在这里插入图片描述

接口定义

RES：复位引脚
D/C：数据/命令标志（0，命令；1，数据）
CS: 片选信号
CLK： SPI时钟线
DIO：SPI数据线
NC：不连
GND：模块接地端
VCC：模块电源端

OLED驱动原理

在这里插入图片描述
0.96的OLED本质上是一个LED拍成的阵列，其长度为128，宽度为64，一共有128*64个像素点，每一个像素点都有相对应的坐标。我们需要在频幕上显示动画，只需要知道频幕上对应位置上的LED是否亮起，就可以驱动OLED屏幕。

显然如果我们一个点一个点去点亮/熄灭的效率是很低的，我们也不会去这样做，一般的做法是通过驱动OLED驱动芯片，完成对OLED的显示。通常是使用SSD1306.

所以OLED的驱动原理本质上是去SSD1306芯片，但是关于SSD1306的驱动方法，我们不需要太过纠结，其中的原理太过复杂，我们只需要熟悉相应的库函数就可以。下面我们来介绍一下需要用到的库函数：

在这里插入图片描述
注意：这里的引脚可以根据需要自行修改，修改后需要在OLED.H头文件中修改对应引脚定义。

另外，OLED.C还需要搭配对应的字库使用，其具体代码如下：

以上就是所有的OLED函数，下面我们尝试使用他们写一个界面

实战部分

效果展示

大概效果就是有两个页面，第一个页面显示时间、日期界面，第二个界面为设置界面，通过按键0可以选择需要现实的界面。按键1可以选择需要修改的内容，不过修改部分还没有实现，有兴趣的可以自行实现一下。
在这里插入图片描述
