基于CAN总线的SPWM波控制器的设计

Design of SPWM Wave Controller based on CAN Bus

运用微控制器STM32和FPGA芯片设计一种频率和脉冲个数任意可调的SPWM脉冲波。介绍了总体设计方案、主要硬件电路和软件设计。STM32负责通信处理和数据存储,FPGA控制输出SPWM波,与外界通信采用CAN总线技术。

Using STM32 micro controller and the FPGA chip to design a SPWM pulse wave, whose frequency and pulse number can adjust arbitrarily. This paper introduces the overall design scheme, main hardware circuit and software design. STM32 is responsible for the communication processing and data storage, the FPGA output SPWM wave, and communication with the outside world using CAN bus technology.
