/*------------------------------------------------------------------------
 提供BSP对外接口说明,应用参照本文件,应完全了解各驱动的使用
 每种驱动的接口说明包括3部分: 设备名,控制功能码,函数原型;
 外部应用可由统一接口访问,或具体驱动接口访问;
 建议使用统一接口, 可提高代码的移植性和定制性,如对串口的引用;
 具体驱动的函数原型本不应该暴露在应用前面,但为了信息的集中,也放在这里; 
 添加新驱动,先在这里添加说明,并在bspInit()中注册即可.
 简化Fmem的接口,代码以后也可重用,为了简化,不使用统一驱动接口.
