8 // 资源配置情况：VREF既作为内部A/D基准，又输出给外部电路
9 // 1根DA
10 // 3根A/D
11 // 4根串口现
12 // 1根复位
13 // 2根电源
14 // 一个定时器+
15 // 两个GPIO,
16 // 3根SPI，
17 // Target: C8051F33x
18 // Tool chain: KEIL C51 6.03 / KEIL EVAL C51
19 // 程序说明：
20 //
21 // 用在带GPS天线短路保护的便携式SVA导航仪上
22 // SJQQC版本，带日期输出
23 // 带天线短路告警，没告警输出为0，有告警输出为85
24 // 算法改为：（X * 5 - Y）/ 25 = 角度 X：采样数字 Y：基准
25 // 本程序用于500套正式生产
26 // 与SDA程序的区别：1.FM接口定义变动
27 // 2.增加日期
28 // 3.增加长按关机，同时给WINCE存盘提供时间
29 // 4.增加背光调节协议
