8 // 資源配置情況：VREF既作為內部A/D基準，又輸出給外部電路
9 // 1根DA
10 // 3根A/D
11 // 4根串口現(xiàn)
12 // 1根復位
13 // 2根電源
14 // 一個定時器+
15 // 兩個GPIO,
16 // 3根SPI，
17 // Target: C8051F33x
18 // Tool chain: KEIL C51 6.03 / KEIL EVAL C51
19 // 程序說明：
20 //
21 // 用在帶GPS天線短路保護的便攜式SVA導航儀上
22 // SJQQC版本，帶日期輸出
23 // 帶天線短路告警，沒告警輸出為0，有告警輸出為85
24 // 算法改為：（X * 5 - Y）/ 25 = 角度 X：采樣數(shù)字 Y：基準
25 // 本程序用于500套正式生產
26 // 與SDA程序的區(qū)別：1.FM接口定義變動
27 // 2.增加日期
28 // 3.增加長按關機，同時給WINCE存盤提供時間
29 // 4.增加背光調節(jié)協(xié)議
