Abstract
With the rapid development of modern computer technology and Internet technology, the widely applied PC has transited from the era of the personal digital assistants, handheld personal computers and information appliances to the Post-PC era of 3C (computer, communications, consumer electronics). Embedded systems play an increasingly important role, and which is widely used in household appliances, Mobile computer equipment, network equipment, industrial control and simulation, measurement equipment and other various fields. With high integration and high performance-price ratio LPC2214 ARM7 microprocessor is well suited for embedded system design. The study is based on the three-phase transformer platform with LPC2214, has finished the display interface programming, developed the related code, and achieved the intended interface. C language is used for Chinese lattice information, display functions and menu control functions.
