Abstract: 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. Key words: FPGA; ARM; absolute encoder; interface; tamagawa
