带中文字库的128X64是一种具有4位/8位并行、2线或3线串行多种接口方式，内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64, 内置8192个16*16点汉字，和128个16*8点ASCII字符集.利用该模块灵活的接口方式和简单、方便的操作指令，可构成全中文人机交互图形界面。可以显示8×4行16×16点阵的汉字. 也可完成图形显示.低电压低功耗是其又一显著特点。由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构或显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。 基本特性: 低电源电压（VDD:+3.0--+5.5V） 显示分辨率:128×64点 内置汉字字库，提供8192个16×16点阵汉字(简繁体可选) 内置 128个16×8点阵字符 2MHZ时钟频率 显示方式：STN、半透、正显 驱动方式：1/32DUTY，1/5BIAS 视角方向：6点 背光方式：侧部高亮白色LED，功耗仅为普通LED的1/5—1/10 通讯方式：串行、并口可选 内置DC-DC转换电路，无需外加负压 无需片选信号，简化软件设计 工作温度: 0℃ - +55℃ ,存储温度: -20℃ - +60℃ 12864（带字库汉字显示演示程序）

基于单片机的红外门进控制系统设计与制作:我们所做的创新实验项目“基于单片机的红外门控系统”已基本完成，现将其工作原理简要说明。该系统主要分为两大部分：一是红外传感器部分。二是单片机计数显示控制部分。基本电路图如下:其中红外传感器部分我们采用红外对管实现，红外对管平行放置，平常处于接收状态，经比较器输出低电平，当有人经过时，红外线被挡住，接收管接收不到红外线，经比较器输出高电平。这样，当有人经过时便会产生一个电平的跳变。单片机控制部分主要是通过外部两个中断判断是否有人经过，如果有人经过，由于电平跳变的产生，进入中断服务程序，这里我们采用了两对红外传感器接到两个外部中断口，中断0作为入口，实现加1操作，中断1作为出口，实现减1操作。另外，我们通过P0口控制室内灯的亮暗，当寄存器计数值为0时，熄灯，不为0时，灯亮。显示部分，采用两位数码管动态显示，如有必要，可以很方便的扩展为四位计数。精益求精！在实验过程中，我们走了非常多的弯路,做出来的东西根本不是自己想要的,我们本想做成室内只有一个门的进出计数，原理已清楚，即在门的两边放置两对红外对管，进出时，挡住两对对管的顺序不同，因此，可判断是进入还是出去，从而实现加减计数，编程时，可分别在两个中断服务程序的入口置标志位，根据标志位判断进出，详细内容在程序部分。理论如此，但在实际过程中，还是发现实现不了上述功能，我们初步判定认为是程序掌握得不够好,相信随着自己对单片机了解的深入,应该会做出更好的 (因为我们是临时学的单片机),程序的具体内容如下： $MOD52 ORG 0000H LJMP MAIN ORG 0003H LJMP 0100H ORG 0013H LJMP 0150H ORG 0050HMAIN: CLR A MOV 30H , A ;初始化缓存区 MOV 31H , A MOV 32H , A MOV 33H , A MOV R6 , A MOV R7 , A SETB EA SETB EX0 SETB EX1 SETB IT0 SETB IT1 SETB PX1NEXT1: ACALL HEXTOBCDD ;调用数制转换子程序 ACALL DISPLAY ;调用显示子程序 LJMP NEXT1 ORG 0100H ;中断0服务程序 LCALL DELY mov 70H,#2 djnz 70H,next JBC F0,NEXT SETB F0 CLR P0.0 LCALL DELY0 SETB P0.0 MOV A , R7 ADD A , #1 MOV R7, A MOV A , R6 ADDC A , #0 MOV R6 , A CJNE R6 , #07H , NEXT CLR A MOV R6 , A MOV R7 , ANEXT: RETI ORG 0150H ;中断1服务程序 LCALL DELY mov 70H,#2 djnz 70H,next2 JBC F0,NEXT2 SETB F0 CLR P0.0 LCALL DELY0 SETB P0.0 CLR C MOV A , R7 SUBB A , #1 MOV R7, A MOV A , R6 SUBB A , #0 MOV R6 , A CJNE R6 , #07H , NEXT2 CLR A MOV R6 , A MOV R7 , ANEXT2: RETI ORG 0200HHEXTOBCDD:MOV A , R6 ;由十六进制转化为十进制 PUSH ACC MOV A , R7 PUSH ACC MOV A , R2 PUSH ACC CLR A MOV R3 , A MOV R4 , A MOV R5 , A MOV R2 , #10HHB3: MOV A , R7 ;将十六进制中最高位移入进位位中 RLC A MOV R7 , A MOV A , R6 RLC A MOV R6 , A MOV A , R5 ;每位数加上本身相当于将这个数乘以2 ADDC A , R5 DA A MOV R5 , A MOV A , R4 ADDC A , R4 DA A ;十进制调整 MOV R4 , A MOV A , R3 ADDC A , R3 DJNZ R2 , HB3 POP ACC MOV R2 , A POP ACC MOV R7 , A POP ACC MOV R6 , A RET ORG 0250HDISPLAY: MOV R0 , #30H MOV A , R5 ANL A , #0FH MOV @R0 , A MOV A , R5 SWAP A ANL A , #0FH INC R0 MOV @R0 , A MOV A , R4 ANL A , #0FH INC R0 MOV @R0 , A MOV A , R4 SWAP A ANL A , #0FH INC R0 MOV @R0 , A MOV R0 , #30H MOV R2 , #11111110BAGAIN: MOV A , R2 MOV P2 , A MOV A , @R0 MOV DPTR , #TAB MOVC A , @A+DPTR MOV P1 , A ACALL DELAY INC R0 MOV A , R2 RL A MOV R2 , A JB ACC.4 , AGAIN RETTAB: DB 03FH , 06H , 5BH , 4FH , 66H , 6DH , 7DH , 07H , 7FH , 6FH ;七段码表DELY: MOV R1,#80D1: MOV R2,#100 DJNZ R2,$ DJNZ R1,D1 RET DELAY: MOV TMOD , #01H ;延时子程序 MOV TL0 , #0FEH MOV TH0 , #0FEH SETB TR0WAIT: JNB TF0 , WAIT CLR TF0 CLR TR0 RETDELY0: MOV R1, #200D3: MOV R2,#250 DJNZ R2,$ DJNZ R1,D3 RET END 该系统实际应用广泛。可用在生产线上产品数量统计、公交车智能计数问候（需添加语音芯片）、超市内人数统计等公共场合。另外，添加串口通信部分便可实现与PC数据交换的功能。 由于，实验简化了，剩下不少零件和资金，所以我们又做了两项其他的实验。
