基于讯通公司的nrf2401单片机进行的无限通信程序。-NRF2401 show based on the company

单片机8051,用了串口缓冲区收发合一的方式,适合于半双工通信-8051 single-chip, using the serial port one way to send and receive buffer, suitable for half-duplex communication

DAC1230是一个12位的模数转换的芯片!而使用时候是在8位的单片机上运行,所以需要注意高四位和低八位的写入时序-DAC1230 is a 12-bit analog-digital conversion chips! Use of time in the 8-bit single-chip run, so it is necessary to pay attention to the high four and low eight write timing

一个单片机上的sd卡驱动程序，支持fat32，fat16等文件系统，很有参考价值。-A microcontroller on the sd card driver and support fat32, fat16 file system, etc., of great reference value.

本设计主要是运用单片机设计一个最小系统――电子时钟，它具有24小时计时功能，能够对时间进行调整，并且能实现时、分、秒的显示，同时还有内设闹钟，时间到时候会响铃，响铃时可以通过按键控制延时再启动或关断。与此同时还设置了整点报时功能；并采用采用了软件去抖的方法扫描键盘，动态刷新显示数码管，并通过查表实现译码输出时间等编程方法；-This design is the use of single-chip design of a minimum system- Electronic clock, it has a 24-hour timer function, capable of time to adjust, and can achieve the hours, minutes and seconds display, but also equipped with alarm clocks, time to When ringing the bell to ring when the button control can delay re-start or shutdown. At the same time also set up the whole point timekeeping function and adopt the use of the software to scan the keyboard shaking method, dynamic refresh display digital tube, and through the realization of decoding look-up table output time programming method
