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

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_uart_rec_ 的公共协议包(关键的结构体)的声明------struct _s_uart_rec_
