基于STC12C5A60S2单片机开发的简易波形发生器，包括DDS芯片AD9833，液晶HB12864等源程序，能够产生正弦波、方波、三角波等波形。系统控制采用红外遥控的方式，能够方便的对波形幅度和频率等进行调节。随源码附上调试心得一份。-Simple waveform generator based on STC12C5A60S2 microcontroller development, including DDS chip AD9833, LCD HB12864 and other source, can generate sine wave, Fang Bo, triangle wave, etc.. The system controls the way of infrared remote control, and can adjust the amplitude and frequency of the wave.
