一个很好的单片机学习资料，实用的例子有助于你…

又一个LCD1602的例程（主要是最近正在做相关的工作），已经调试通过。-Another LCD1602 routine (mainly related to the work being done recently), have been debugging through.

串口程序，内有详细的注释，是参考网上流传的串口调试助手写的，在此进行了分栏显示的改进，学习者也可以将其中的控件属性设置为可见，实现和串口调试助手一样的功能。-Serial process, with detailed notes, with reference to the spread of online serial debugging assistant written in this column have been shown to improve, learners can also control which property is set to visible, to achieve and serial debug Like assistant functions.

单片机系统上电后，P0 口和 P1 口都被清 0。然后，你规定一个由 6 个数字构成的序列（每个数字从 0～F 中选取），比如 E、8、9、0、7、F。然后每次当单片机检测到外部中断 0发起中断时间时，读取 P0 口和 P1 口上的状态值，当连续 6 次外部中断事件的对应的数字序列构成你所设定的序列后（举例来说，如果 P0.0 是 1，P0 和 P1 的其他管脚是 0，那么我们称为检测到一次数字 0），从串口打印输出一幅类似下图的 16×16 的ASCII码的圣诞树图片。-Single-chip microcomputer system after power, P0 and P1 mouth I have been ching 0. Then you set a six figure constituted by the sequence (each number from 0 ~ F in selected), for example, E, 8,9,0,7, F. And then each time a single-chip detects external interrupt 0 initiated interruption time, I read the P0 and P1 mouth on the state value, when a row 6 times the corresponding external interrupt events constitute digital sequence set your sequence (for example example, if P0.0 is 1, P0 and P1 of the other pin is 0, then we called a number of detected 0), a printout from the serial port under similar 16 × 16 map of the ASCII code of the Christmas tree图片.

利用pic单片机的定时计数器测量汽车轮速，并利用串口将数据发送出去。-Using pic microcontroller timing counter measure vehicle wheel speed, and the use of serial data sent.
