// 资源配置情况：VREF既作为内部A/D基准，又输出给外部电路
// 1根DA
// 3根A/D
// 4根串口现
// 1根复位
// 2根电源
// 一个定时器+
// 两个GPIO,
// 3根SPI，
// Target: C8051F33x
// Tool chain: KEIL C51 6.03 / KEIL EVAL C51
// 程序说明：
//
// 用在带GPS天线短路保护的便携式SVA导航仪上
// SJQQC版本，带日期输出
// 带天线短路告警，没告警输出为0，有告警输出为85
// 算法改为：（X * 5 - Y）/ 25 = 角度 X：采样数字 Y：基准
// 本程序用于500套正式生产
// 与SDA程序的区别：1.FM接口定义变动
// 2.增加日期
// 3.增加长按关机，同时给WINCE存盘提供时间
// 4.增加背光调节协议
