ASCII码
ASCII码是一套数字到字符的映射标准它规定了用什么数字表示什么字符
例如char a ‘#’; 等效于char a 0x23; char a ‘0’; 等效于char a 0x30; char s[] “hi”;等效于 char s[] {0x68, 0x69, 0x00};
汉字编码
汉字编码是一套数字到汉字的映射标准它规定了用什么数字表示什么汉字 汉字编码有多种方案常用的有GB2312/GBK/GB18030和Unicode/UTF-8
GB2312国内汉字编码
GB2312编码下char s[] “好”; 等效于 char s[] {0xBA, 0xC3, 0x00}; char s[] “你好”; 等效于 char s[] {0xC4, 0xE3, 0xBA, 0xC3, 0x00};
UTF-8是Unicode万国码的传输格式支持所有国家的文字
UTF-8编码下 char s[] “好”; 等效于 char s[] {0xE5, 0xA5, 0xBD, 0x00}; char s[] “你好”; 等效于 char s[] {0xE4, 0xBD, 0xA0, 0xE5, 0xA5, 0xBD, 0x00};
移植文件时一定选择合适的汉字编码文件如果没有可以使用编码转换软件进行转换文件的编码

单片机主频高的可以在通信函数内加一些延时
SSD1306简介 SSD1306是一款OLED/PLED点阵显示屏的控制器可以嵌入在屏幕中用于执行接收数据、显示存储、扫描刷新等任务
驱动接口128个SEG引脚和64个COM引脚对应128*64像素点阵显示屏
内置显示存储器GDDRAM128*64 bit 128*8 Byte
SRAM 供电VDD1.65~3.3VIC 逻辑VCC7~15V面板驱动
通信接口8位6800/8080并行接口3/4线SPI接口I2C接口
由于SSD1306供电相关的升压电路OLED模块可以只接3.3V。能不能接5V需要看电路图是否有5V到3V的降压电路
模块引脚更改
更改I2C或者SPI的通信引脚即可

注意I2C、SPI串行通信不能读GDDRAM但可以通过先修改软件的缓存区再通过协议GDDRAM通过读写缓存区间接读取GDDRAM。内存较小的单片机不能使用缓存区应该直接写入GDDRAM。
