摘要
采用单片机AT89C2051和数模转换器AD7226实现通过串口程控毫伏级精度的±30 V宽范围直流线性电源,并可作为三角波、正弦波的波形发生器。通过计算机可方便地调节电源电压,设定输出波形的频率和幅值,并用数码管现场显示。
±30 V width range DC linearity power supply with control accuracy of mV was come true using AT89C2051 and AD7226. And it could be used as a triangle and sine wave generator as wel . The voltage of power supply was adjusted. The frequency and amplitude of exporting wave were set up. The measure result was shown using numerical code.
