前不久使用cc2530写过LCD5110作显示，最近学习stm32就简单的写了，用stm32对lcd5110的初始化及显示功能。
还是和之前写了两种显示的方法：
- 万能显示(行数要/8，详细见后的数据手册)
/*
这个函数可以自己设定显示的内容的大小，需用取模软件得到待显示的数据；
在取模时需注意取模方式，我这里所有的取模都设置是（纵向取模、字节倒序）方式
*/
// 设置 X,Y起点； 行（/8）、列大小 数组地址名
void LCD_display(unsigned char X,unsigned char Y,unsigned char row,unsigned char col,unsigned char *data);
- 指定格式显示（更多可以看CC2530学习笔记之Nokia 5110LCD程序）
