摘　　要：介绍了一种基于STM32的双通道参数可调PWM波形发生器的设计方法。该系统主要由PC机、STM32处理器、USB转串口模块以及光电隔离模块构成。参数可调的功能由基于LabVIEW的GUI软件实现,通过给STM32最小系统发送数据,来控制输出PWM波形的各个参数。在PC机上利用LabVIEW的GUI软件对PWM波形发生器进行测试,实测结果表明:基于STM32F407的PWM波形发生器设计方案是可行的,测量结果能够满足系统设计需求,且可以通过GUI软件进行实时查询。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.
