嵌入式在Keil51

本库利用51的timer2，9600bps适用于有片内外部存储器的51芯片占用32byte缓存，重写putchar,getchar函数，循环队列，后台操作。-for the use of timer2 51, 9600 applied to the external memory unit within the occupied 32byte 51 chip cache, rewritten putchar, getchar function, circulating cohort, background operation.

里面包含用visual c++编译的程序，可完全适用于数码管（秒表）的应用.-Which contains with visual c++ compiler of the process, can be fully applicable to the digital control (stopwatch) applications.

MCS-51单片机有5个中断源，其中两个是由-INT0、-INT1引脚输入的外部中断源；另外三个是内部中断源即由T0、T1的溢出引起中断和串行口发送完一个字节或接收到一个字节数据引起中断。触发外部中断有两种方式，即下降沿引起中断或低电平引起中断。当编程TCON中的ITi（i=0、1）为1时，则引起触发的方式为边沿触发方式，反之(ITi=0)为低电平触发方式。每个中断源的中断请求能否得到响应要受两级“开关”的控制，即一个总“开关”-MCS-51 single-chip has five interrupt sources, two of which are by-INT0,-INT1 pin input external interrupt source the other three internal interrupt sources from the T0, T1 overflow caused by the disruption and serial port sending or receiving end of a byte to a byte of data caused by interruption. Triggered external interrupt has two modes, namely, falling edge or low-level disruption caused disruption caused. When programming TCON in ITi (i = 0,1) for the 1:00 has been the subject of a way to trigger the way to the edge of the trigger, on the contrary (ITi = 0) for low-level trigger mode. Each interrupt source interrupt request can be subject to levels in response to
