摘　　要：针对绝对式编码器与ARM之间的通信问题,设计了基于FPGA的ARM与绝对式编码器的硬件接口电路。根据ARM和编码器之间的通信流程,利用有限状态机和模块化设计思想进行软件编程。结果表明,该设计接口能够快速、准确地实现ARM和编码器之间的通信。To solve the communication problem between ARM and absolute encoder, a hardware interface based on FPGA was devised. According to the communication process, the interface was designed on the concept of finite state machine and modular method. The test results show that the designed interface can swiftly and accurately realize the communication between ARM and encoder.
