This paper introduces a design method of dual channel parameter adjustable PWM waveform generator based on STM32. The system is mainly composed of PC, STM32 processor, USB module and photoelectric isolation module. The function of adjustable parameters is realized by GUI software based on LabVIEW. By sending data to the STM32 minimum system, the parameters of the output PWM waveform are controlled. Finally, the PWM waveform generator is tested on the PC using the GUI software of LabVIEW. The test results show that the design of PWM waveform generator based on STM32F407 is feasible. The measurement results can meet the system design requirements, and can be inquired by the GUI software in real time.
