说明：  介绍一种基于单片机控制的多功能直流稳压电源的设计方案。该电源简单易用 ,精度高、成 本低 ,可以用作信号发生器 ,产生输出正弦波、方波、三角波、锯齿波等多种波形信号 通过软件升级很容 易实现功能扩展。
(introduced a microcontroller-based control of the multi-purpose DC power supply design. The Power simple to use, high accuracy, low cost, can be used to signal generator, the output sine wave, square wave, triangular wave, sawtooth waveforms and other signal through software upgrades are easy to achieve functional expansion.)
