On an Internet Interface in an Embedded POS System for Internet of Things

摘要

This paper designs and implements an Internet interface in an embedded POS system based on Webit,an embedded platform and interface for Internet of things which is a self-owned intellectual property of Lab.of Embedded Technology,Northeastern University,China.The Internet interface is designed and implemented on an 8-bit RISC micro-controller and Ethemet Network Interface Controller,with a real-time OS-WebitOS 2.0 strictly conforming to TCP/IP protocol requirements.Then experiments of testing functions and the performance of the embedded POS system are performed.And results show that the POS system based on Webit has a practical application value with properties such as low cost,and capabilities of simple network configuration and remote management.
