OLED屏幕介绍

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。

接线说明：

 OLED屏幕显存

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。

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

·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

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“。

简单来说OLED屏幕有128x64个像素格，竖向有128列，横向有64行，而把横向的64行分为8页，每页有8行，比如要设置光标起点：


void OLED_SetPos(unsigned char x,unsigned char y)
{WriteCmd(0xb0 +y);//设置页，0xb0代表第0页WriteCmd((x&0xf0)>>4|0x10);//设置列，获取列的高四位WriteCmd((x&0x0f)|0x01);//设置列，获取列的低四位}
