介绍了Java编程语言的J2ME平台向凌阳SPCA556G平台的移植．在设计过程中首先

对开发平台，GPS的定位原理，NMEA0183协议进行了了解．然后深入的分析了J2ME平台的结构。根据KVM和MIDP的各自特性分别进行移植，最终实现J2ME的移植要求．-Introduced the Java programming language of the J2ME platform to platform, porting Sunplus SPCA556G. In the design process first development platform, GPS positioning theory, NMEA0183 protocol understanding. Then in-depth analysis of the J2ME platform structure. According to the respective characteristics of KVM and MIDP transplant, respectively, and ultimately J2ME porting requirements.
