OLED屏幕

OLED即有机发光管(Organic Light-Emitting Diode,OLED)。OLED显示技术具有自发光、广视角、几乎无穷高的对比度、较低功耗、极高反应速度、可用于绕曲性面板、使用温度范围广、构造及制程简单等有点，被认为是下一代的平面显示屏新兴应用技术。

OLED显示和传统的LCD显示不同，其可以自发光，所以不需要背光灯，这使得OLED显示屏相对于LCD显示屏尺寸更薄，同时显示效果更优。

常用的OLED屏幕有蓝色、黄色、白色等几种。屏的大小为0.96寸，像素点为128*64，所以我们称为0.96oled屏或者12864屏。

OLED屏幕特点

1.模块尺寸：23.7 *23.8mm
2.电源电压：3.3-5.5V
3.驱动芯片：SSD1306
4.测试平台：提供 k60/k10,9s12XS128,51,stm32，stm8等单片机

OLED屏幕显存

在这里插入图片描述
OLED本身是没有显存的，他的现存是依赖SSD1306提供的，而SSD1306提供一块显存。

SSD1306显存总共为128*64bit大小，SSD1306将这些显存分成了8页。每页包含了128个字节。

OLED屏幕原理

STM32内部建立一个缓存(共128*8个字节），每次修改的时候，只是修改STM32上的缓存(实际上就是SRAM)，修改完后一次性把STM32上的缓存数据写入到OLED的GRAM。

这个方法也有坏处，对于SRAM很小的单片机（51系列）就比较麻烦。

OLED屏幕常用指令

在这里插入图片描述
命令0X81: 设置对比度。包含两个字节，第一个0X81为命令，随后方法是的一个字节要设置这个对比度，值越大屏幕越亮。

命令0XAE/0XAF: 0XAE为关闭显示命令，0XAF为开启显示命令

0X8D: 包含两个字节，第一个为命令字，第二个为设置值，第二个字节的BIT2表示电荷泵的开关状态，该位为1开启电荷泵，为0则关闭。模块初始化的时候，这个必须要开启，否则看不到屏幕显示。

命令0XB0~B7:用于设置页地址，其低三位的值对应GRAM页地址。

命令0X00~0X0F：用于设置显示时的起始列地址低四位。

命令0X10~0X1F: 用于设置显示时的起始列地址高四位。

OLED屏幕字模软件的使用

OLED点阵的点亮方式，举个显示”P”的例子，最左边位最高位P7。
在这里插入图片描述
1.可以看出，要想显示”P”，首先写入0x1f,则显示一个竖杠，之后控制器自动水平移动到下一列。

2.再写入0X05,则出现两个小横杆，这个两个横杆就是0X05中0000 0101中两个1所处的位置，写完第二列后，控制器自动跳到第三列.

3.再写入0X07,第四列写入0X00后，P就显示出来了。这也说明，即使你只想再一列的最上端显示一个小点，即写入0X01.

4.即你不能一次性控制一个点阵，只能一次性控制八位点阵，即一列点阵。这也决定了字模选择的取模方式为“列行式“。

遇到的问题

问题一，oled显示花屏

看下图，oled初始化的时候出现的
在这里插入图片描述

两个延时函数，第一个不会花屏，第二个延时函数会花屏，具体原因不清楚。

问题二，oled显示错误

因为对代码不熟悉，想让他打印三个字，而不是两个字，我仿写了个OLED_ShowMouMou(如下图),然后发现为啥我显示了三个字，还多显示了三个哞字的上班部分，第三个哞字的上半部分乱码。
在这里插入图片描述
后面我试了试四个for然后发现，第二行下班部分就补齐了，显示了六个字，因为一个汉字需要16*16两行，那么只需要两个for，我当时以为for跟字数有关，所以导致了显示问题。

看下图字库
在这里插入图片描述
可以发现一个字两行，一行是1616，一行有16列，没个都是16进制数，所以一行是1616
