Can produce 4 kinds of waveform: square wave, sine wave, sawtooth wave, triangle wave. Waveform switching and frequency regulation by buttons. The waveform amplitude is adjusted by potentiometer. Using 51 single chip +DAC0832+ op amp + independent button design, to achieve a simple signal (waveform) generator function. Data containing C language source code, PROTEL format schematics and PCB diagram, simulation files and WORD documentation, is the production of easy signal generator is a good reference.
