There are many design methods of function signal generator, using the function signal generator design has advantages of flexible programming, function more to expand the SCM to design the function signal generator can generate sine wave, triangle wave, square wave, and realize the duty cycle regulation of frequency and waveform, and the LCD screen display name and wave frequency, adjust the waveform switching and frequency and duty cycle can use the button to achieve. In programming language, we choose the more familiar with the C language, so in the debugging period waveform and hardware interface easier to play their own advantages. Through the design and post long time debugging, all the functional design have been achieved.
