C8051F单片机是完全集成的混合信号系统级芯片（SoC），具有与8051兼容的高速CIP-51内核，与MCS-51指令集完全兼容，片内集成了数据采集和控制系统中常用的模拟、数字外设及其他功能部件；内置FLASH程序存储器、内部RAM，大部分器件内部还有位于外部数据存储器空间的RAM，即XRAM。C8051F单片机具有片内调试电路，通过4脚的JTAG接口可以进行非侵入式、全速的在系统调试。-C8051F is a fully integrated mixed-signal system-on-chip (SoC), and 8051 compatible with the high-speed CIP-51 core, and MCS-51 compatible instruction set, on-chip integration of the data acquisition and control system used in analog and digital peripherals, and other functional components; embedded Flash program memory, internal RAM, the majority of devices located within the external data memory space of RAM, XRAM. C8051F with on-chip debug circuit, through the four legs of the JTAG interface can be non-invasive, full-speed debugging of the system.

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.
