Nokia 3310手机的点阵LCD模块不仅小巧、省电、驱动容易，而且价钱也便宜，因此，可以用单片机来驱动该模块，并应用在各种产品上。
3310LCD买来时如下图所示，可以把金属外框、键盘和听筒部分去掉：
3310LCD的工作电压范围是2.7－3.3V，MCU和LCD之间使用SPI接口传输数据。
LCD模块的引脚排列：从模块的背面看，管脚排列顺序从左至右分别为1至8脚。如下图所示：
主要程序代码：
void LcdWriteData(BYTE xData);
void LcdWriteCmd(BYTE xCmd);
void LcdClear();
void LcdSetXY(BYTE x,BYTE y);
void LcdWriteChar6X8(BYTE c);
void LcdWriteStr6X8(BYTE x,BYTE y,char *s);
void LcdDrawBmp(BYTE X,BYTE Y,const BYTE* map,BYTE nWidth,BYTE nHeight);
void main(void);
