Embedded systems are apply to the dedicated computer system,whose application system is strict at functionality、reliability、cost、size、power requirements and so on.They use application as their center and computer technology as their base,at the same time,their software and hardware can be cutted out.With the development of infomationization、intelligentize and networking,embedded systems technology will gain even broader room for development in industrial control,traffic management, information appliances,environmental engineering and robots,and other fields.This graduation project is a control program design,which is based on the topics of data acquisition card LPC2214.The system selects one kind of the LPC2000 series chip-LPC2214 microcontroller chip-to achieve the purpose of learning and design,which through displaying curve in the liquid crystal screen SED1335.Its main features include the external equipment acquisition and control of some parameters, including display, data processing and other control functions.This paper introduces the devise of the entire hardware and software. Including hardware schematic design, the ADS software integrated development environment, and LCD module controller driver design.
