Arbitrary waveform generator is widely used in experiment and practical work as signal sourer. Apply the HSO function of 8OC198KC MCU to generate PWM waveform, then use the PWM to compose arbitrary waveform. The concrete hardware control circuit and the software realization method are presented. Then take the three-phase SPWM waveform generator for example, pot forward the application circuit and show the result of test. Experiment shows that the waveform distortion of sine, triangle and sawtooth is small and the operation is simple. The performance is high.
