To design a microprocessor controlled signal generator. Control the use of SCM systems produce a variety of waveforms, these waveforms include square, triangle wave, sawtooth, sine wave and so on. Waveform generated by signal generator frequency and amplitude can be adjusted. Can be arbitrarily changed by software, the signal waveform. Basic requirements: 1. Have three or more waveforms. Such as sine, triangle, rectangle wave. (2) maximum frequency of not less than 500Hz. And adjust the frequency according to certain rules, such as the cycle by 1T, 2T, 3T, 4T or 1T, 2T, 4T, 8T change. 3 adjustable amplitude, peak to peak in the 0- 5V between changes. Extended requirement: to produce more frequency and waveform.
