AD_count_countdown
说明: 设置3个功能键:当某一功能键被按下后,进入相应的功能模式。3个功能有:
1)8路数据采集功能:通过调节可变电阻实现0-5V的电压输出作为8路输入信号使用,每路信号用2位LED显示采集的结果。报警:任意一路超过某一门限(可自己设定)时,发出报警(声音+灯闪烁,并通过灯指示是哪一路报警),同时停止采集。2)计数功能:利用计数功能键,实现每按一次按键,LED显示加1,从0-99计数。3)秒表功能:只用一个键控制。按下一个按键后时钟启动,从零开始计时,计时间隔0.01秒,再按一次后停止。再按一次后清零。如此循环。
本设计采用2个MAX7221串行驱动2个8路数码管显示,更节省单片机I/O口。(AD、count、countdown)

1、时钟配置和CLKOUT
配置系统的时钟,用于单片机的学习,基于开发板LPC1114,程序虽然比较小,却是一个完整的模块,可以作为一个模板,在此基础上添加其他外设及相关编程。(Configuring the clock of the system is used for the learning of MCU. Based on the development board LPC1114, the program is relatively small, but it is a complete module, which can be used as a template, on which other peripherals and related programming are added.)

绿色版(见内部图)
基于MSP430F5438A的AD9854驱动,AD9854的DDS核具有48位的频率分辨率(在300M系统时钟下,频率分辨率可达1uHZ)。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)
