【 摘 要 】
Aiming at the demand of PWM waveform in the fields of communication, measurement, control, electronic power, detection and so on, in this paper, the hardware circuit of PWM generator based on OMAP-L138 chip is designed, and the control program of PWM generator is designed with the idea of layered design. The correctness of the circuit design and control program of the PWM generator is tested and the performance indexes of the PWM generator circuit such as the CPU consumption rate and the precision of the CPU duty cycle are tested. The experimental results show that the PWM generator has the advantages of simple circuit structure, high control precision, high flexibility and good portability.
