诺基亚3310液晶显示模块资料及的应用.doc

诺基亚3310液晶显示模块资料及的应用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，最近网上常见到不少朋友都在用单片机来驱动该模块，制做出很多作品。实验目标在LCD上显示和移动汉字；在LCD上显示英文字符串；在LCD上显示位图。实验电路图及工作原理由于3310LCD的工作电压范围是2.73.3V，因此实验中使用一个3.3V的稳压二极管D1将5V电源稳压为3.3V左右，为MCU和LCD供电。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：注意： LCD模块的引脚即使用导线直接焊接上，也要用东西将金属引脚压下去，否则还是不能接触到内部电路实验源程序主程序：文件名是3310LCDTest.c #include #include #include lcd.h#include bmp.h/*/void main(void) OSCCAL=0x99;/ 8M系统内部时钟校准/设置MCU的I/O口DDRB |= LCD_RST | LCD_DC | LCD_CE | SPI_MOSI | SPI_CLK| 0X02;SPSR |= BIT(SPI2X);/ 设置SPI时钟倍速SPCR |= BIT(SPE)|BIT(MSTR);/ 使能SPI接口，主机模式，4M时钟LCD_init();
