下午抽了点时刻在调试ARM7，想把前次用ATMEGA8做的GPS移植到ARM7上去，下午移植了LCD和串口，可是还没把串口中止程序编写好。按键也还没移植，其他OK了，再花点时刻就能够完整了。我想GPS和GSM结合起来，这样能够做个比较有用的东西。自己玩玩很不错！哈哈！再接再厉持续尽力……

/*****File Function : lcd10265液晶显现程序 *****/
/*****Program Author : ZhengWen(ClimberWin) *****/
/*****MCU ： LPC2103F 外部11.0592M晶振 *****/
/*****Compile Date : 2010/01/13 *****/

/*************************************************************/
//编译环境 KEIL for ARM
//修正时刻2010年2月9日，能够串口输出数据，接纳数据，而且LCD上显现
/*************************************************************/
//修正时刻2010年2月10日
//修正内容：一向串口和LCD显现不能一起用，后来发现是设置好PLL后因为时序太快，导致液晶不能显现
// 调整好时序后液晶能够正常显现。
//LCD GUI移植成功，还需要移植按键
