* 硬件结构： PA0-5对应６个ＬＥＤ数显管的位 ，PC0-7对应各ＬＥＤ数显管的段 ，PB4-7为键盘。 * 软件描述： 上电后，时钟从00.00.00（时/分/秒）自动走时，在走时状态时 ， 按PB4（设定 * 键）超过3秒可循环选择调整时间/工作参数 ，接着按PB5以确定选择的操作 ，进入调整操作后 ， * 按PB5选择欲调整参数，按PB6（增加键）完成调整参数操作 。按PB7，进入时控运行，PB1亮， * 再按PB7停止时控运行，回显走时。在定时到时，PB0点亮。- * Hardware architecture: PA0-5 corresponds 6 LED numbers to reveal the tube the position, PC0-7 corresponds each LED number to reveal the tube the section, PB4-7 is a keyboard. * Software description: After on electricity, clock from 00.00.00 (when/a minute/second) is in luck automatically, when is in luck the condition, according to PB4 (hypothesis * The key) surpasses for 3 seconds to be possible to circulate the choice time/operational parameter, then presses PB5 by to determine the choice the operation, after enters the adjustment operation * Wants according to the PB5 choice to adjust the parameter, (increases key) according to PB6 to complete the adjustment parameter operation.According to PB7, enters when controls the mov

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

PIC的资源,用PIC16F505做段码显示的C语言样例-Single and multiple 7-segment displays, multiplexing, and BCD counting on baseline PICs (using the PIC16F505)

I2C的程序 数据传送 非常详细的注释 C语言的 其他的就不用多说了吧-I2C data transmission procedures very detailed notes of the C language other on the right to say the least

汇编 I2C读写FM256程序段 功能完整 可直接调用-FM256 compilation I2C read and write full-featured program segment can be directly called

IO口模拟串口发送，可用于双串口，可被其他程序调用 void rs2_send_byte(uchar cByte) 向串口发送一个字节-Send serial port analog IO, can be used for dual-serial port, other procedures can be called void rs2_send_byte (uchar cByte) sends a byte to the serial port

秒表程序-Stopwatch program

1602的串行输入不用 那么多的引脚就可可以实现1602的读写 显示变量等功能-1602" s serial input pin can not so much can be achieved in 1602 show variable features such as reading and writing
