摘　　要：为解决市场上各种缴费终端的高成本问题,提出了一种基于arm7的嵌入式缴费终端的解决方案。对该方案进行了总体结构的设计,并考虑了在满足缴费功能的条件下设计所需的低端硬件平台。在这基础上选用MiniGUI作为图形人机界面,并分析了MiniGUI的体系结构和消息驱动机制,提供了触摸屏的校正方法并编写用户自己的输入引擎IAL,裁剪和移植嵌入式Linux系统,完成了MiniGUI在SEP4020上的移植。实验结果表明了该设计方案的可行性,且降低了成本,满足嵌入式缴费终端的应用要求。To deal with the cost issues of payment terminal in the market,an Arm7-based embedded solutions for payment terminals is proposed.First of all,the overall structure of the program is designed,considering the payment function to meet the hardware platform is required.Based on the platform the MiniGUI is selected as the man-machine interface graphics,MiniGUI architecture and message-driven mechanism is analyzed,a touch screen calibration method and the preparation of the user＇s own input engine IAL is provided,embedded Linux system is cuted and transplanted,and the MiniGUI transplantation to SEP4020 is completed.Finally,the experiments show that the feasibility of the method is validated,the cost of the system is reduced,and embedded payment terminal applications is meet.
