针对多串口 和 单一串口 有区别 每个串口是独立的还是分开的有讲究 程序是复杂的还是软件应用简单是
个需要平衡的事情.

clib/clib.c:  
公用的函数 	和硬件无关 
放置串行模式(串口等其他通讯总线类的输出)输出的函数,
一些覆盖模式输出的(lcd等固屏输出的)的也可使用  
					void Lc_print(void (*L0pf_send_uc)(char ww), char *dat,...)
-----------------------------------------------------------------------------------------
uartcom/Uprotocol2app  
  协议到应用
  为了适应不同的通讯协议需要不同的uart口来对应 和应用相关

typedef struct _ts_lcm_pro_; 应用协议包的定义?    LCM的协议------------
											L3_UARTcom0_exp_protocol 解析应用协议
-----------------------------------------------------------------------------------------
uartcom/urec2protocol: 接收到的数据放入到指向特定协议的缓存中，和协议的格式有关 一般分为 标头式或者标尾式
公用的串口通讯定义		
 	struct _s_protocol_ 的公共协议包(关键的结构体)的声明------struct _s_protocol_
 							void L1_uart_2buf(struct _s_protocol_ *p)串行数据保存到指向特定协议的缓冲中
--------------------------------------------------------------------------------------------
msp/uartx.c    底层代码	 和cpu相关 缓存发送也放在里面
