Abstract
This paper introduces a system of MCU Read Write Udisk based on SL811HS. This system is composed of MCU, USB interface control unit and high-speed RAM, solving the problem of USB standard interfaces being uninstalled in most data collection equipment, work controller and built-in system and Udisk not being read and written. It emphasizes the analysis of the principle of the system and communication protocol, and presents the method of realizing the hardware and software.
