增加ASCII.C的一个ASCI码(7F),用于虚拟按键用 修改UART串口的命令解析程序，修改RTC的pcf8563中断部分。 精简IIC和smart_timer代码,添加define.h的宏定义。 修改system.c里的消息堆栈的宏定义 增加ii.c函数,支持对eeprom的打包 增加由PLD或者GPIO输出的模拟UART，在6个CLOCK下速度为57.6K 增加消息的优先级功能，消息类型的前4位为消息的优先级，后4位为消息的类型 试用于初学单片机并且想更上一层楼的，或者有些基础，想减少工作量的。-an increase ASCII.C the ASCI code (7F) for the virtual keys with serial UART to amend the order analytic procedures, the revised RTC pcf8563 interruption part. IIC and smart_timer streamline code, add the definition of Acer define.h. The revised system.c news stack macros increase II.c function, support for EEPROM packaged increase from the PLD or GPIO output analog UART, in the next six CLOCK speed of 57.6K news of the priority function of the type of information before news of the four priority levels after four types of information on the trial beginner to a higher level and SCM, or some foundation, we want to reduce the workload.
