51单片机加rt8019硬件平台,上web方案及详细代码-Rt8019 plus 51 single-chip hardware platform, the web program and a detailed code

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态。-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current lighting condition.

主要讲了单片机如何实现自行车测速功能。 十分好。-Mainly talked about how to achieve a bike speed microcontroller functionality. Very well.

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.
