A Multifunctional Terminal Hardware Design for Teaching Assistant

Abstract

Abstract An intelligent handheld terminal for campus was designed to meet the teaching management requirements under the new education situation. This system is composed of fingerprint identification module, wireless communication module, LCD touch screen module and embedded system. So, it can achieve multiple functions. Specifically, we design the hardware schematic diagram and PCB, then devise driver and transplant FreeRTOS operating system according to the working characteristic of each module. The communication protocol between the handheld terminal and the host computer is designed to complete the process of collecting fingerprint attendance and classroom test data and then transmitting those data wirelessly to the host computer. This system will be helpful to improve the campus service and teaching quality.
