C51单片机实现液晶秒表以及简单计算器
电路是一个51最小系统,没有采用总线方式,而简单的连线方式,上有4*4矩阵键盘,一数码管,89S51单片机,串口下载线,数码管显示锁存芯片\\蜂鸣器\\1602液晶.
代码已经调试成功过,可以实现时间的调整.4*4矩阵键盘,第一排前三列是实现小时\\分钟\\秒的加.第二排前三列是实现小时\\分钟\\秒的减.当然还可以通过设置矩阵键盘的键值,来实现加\\减\\乘\\除四则运算,由数码管显示参与运算的数字以及最终的运算结果.-C51 MCU LCD stopwatch and a simple calculator circuit 51 is a minimum system, Bus not used, and simple connectivity, a 4 * 4 matrix keyboard, a digital control, devised microcontroller, Serial download cable, digital chip latches Display \\ buzzer \\ 1,602 LCD. Debugging code has been success, can be achieved period of adjustment .4 * 4 matrix keyboard, the first row is shown in the first three hours \\ minutes \\ plus seconds. shown in the second row is the first three-hour \\ minutes \\ seconds reduction. Of course You can also set up matrix keyboard keys to achieve increases \\ by \\ x \\ In addition to four operators, Digital Display from operations in the number of operations and the eventual outcome.
