adc0809与dac0832做的串级控制，PCB图与程序都值得一看-adc0809 dac0832 do with the Cascade control, PCB plans and procedures are an eye-catcher

自己做的波形发生器的源码和PCB图，能够仿真测试-Waveform generator to do its own source code and PCB map to simulation testing

DAC0832在单片机上的应用,C语言源码,Keil uVision3工程文件,附原理图及说明学习文档 -DAC0832 in SCM applications, C language source code, Keil uVision3 project file, with schematic diagram and descr iption of study documents

可产生4种波形：方波、正弦波、锯齿波、三角波。通过按键进行波形切换及频率调节。波形幅值通过电位器调节。采用51单片机+DAC0832+运放+独立按键设计，实现简易信号（波形）发生器功能。资料含C语言源程序、PROTEL格式原理图及PCB图、仿真文件及WORD说明文档，是制作易信号发生器比较好的参考。(Can produce 4 kinds of waveform: square wave, sine wave, sawtooth wave, triangle wave. Waveform swi
