【摘要】:传统的人机交互数据传输多通过计算机串口或并口实现,数据率低,通常会因数据传输堵塞造成系统响应迟滞。针对此问题,设计一种基于FPGA的ARFI系统USB键盘。通信桥芯片FT245RL作为USB虚拟串口芯片,保证传输方式的便捷与灵活性,同时又提供高数据率的传输通道。通过自定义传输协议使得ARFI系统在人机交互数据传输方面更为快速、稳定、可靠。新增加的Multi多功能键,能在不同工作模式下调节不同的参数值。测试结果表明,键盘能准确、快速、稳定地传输数据,系统灵敏性高。
[Abstract]:The traditional man-machine interactive data transmission is usually realized by computer serial port or parallel port, and the data rate is low, which usually results in the delay of system response due to the data transmission blockage. To solve this problem, a ARFI system USB keyboard based on FPGA is designed. As a USB virtual serial port chip, communication bridge chip (FT245RL) ensures the convenience and flexibility of transmission mode and provides a high data rate transmission channel at the same time. Through the custom transmission protocol, the ARFI system is faster, more stable and more reliable in man-machine interactive data transmission. The newly added Multi multifunction key can adjust different parameter value in different working mode. The test results show that the keyboard can transmit data accurately, quickly and stably, and the system is sensitive.
