Embedded virtual architecture allows you to quickly start the development of single chip microcomputer without having to learn the complex internal principles of single chip microcomputer. You only need to learn all the apis of this architecture. emva can virtualize all single chip microcomputer on the market and provide standard upper level api operation interface
- open emva_create_lib_keilv5 project
- build this project and you will get emva_lib.lib file
- create your project and add emva_lib.lib file to your project
- implements hal interface
Implement some standard implementations of the interface for your target platform
