单片机信号发生器
在现代电子学的电路实验和设备检测中,信号发生器具有十分广泛的用途,与示波器、电压表、频率计等仪器一样,是常用的最普通、最基本的仪器设备之一。各种波形曲线均可以三角函数方程式来表示。能够产生多种波形的电路被称为函数信号发生器。通过对函数波形发生器原理以及构成分析,可设计一种能变换出三角波、方波、锯齿波和正弦波的函数发生器。信号发生器是工业生产、产品开发、科学研究等领域必备的工具,正弦波、三角波、方波是常用的基本测试信号,因此被广泛应用于电子电路、自动控制系统和教学实验等领域。

每次开机都将次数加1 并存储到EEPROM。这样就能直观的看到机器的使用次数。用P1口 LED做为显示,次数大于256是将溢出,按复位模拟开机 或者直接通过开关开机。-Each boot will add a number of times and stored in EEPROM. This will be able to see the intuitive usage of the machine. As with the P1 port LED display, frequency is greater than 256 is the overflow, according to reset the boot, or directly through the analog switch boot.
