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,...)

|
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_
|
|
void L1_uart_2buf(struct _s_uart_rec_ *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
