嵌入式大作业报告

数据排序过程演一、实验目ARM9ARMS3C2410CARMARM二、实验环软件：KeiluVision三、实验要在LCD屏幕上提示用户用矩阵键盘输入8个数字，输入过程显示在屏幕上。输入完成后，屏幕提示按确认键开始排序过程。一定要输满8个数字才能排序；输入过程中若按取消键则8LCD2~3有按键按下后才进行下一步排序。8LED1LCD清除显示；按其他键继续排序过程。四、实验内8LED模块以及LED模块。根据实验例程的复杂程度，我选用LCD模块程序例程作为基本模块，keypad8LED实验程序（1）主程int Initials3c2410'sClock,Interrupt,PortandUART //8LEDrCPLDLEDADDR= //LED BitmapViewTft16Bit_800480((UINT8T*)(g_ucBitmap)); //在LCD显示基本界面 keypad_test(); }（2）8LED显示学号模unsignedcharf_szDigital[10]void inti;for(i=0;i<8;i++){iic_write_8led(0x70,0x10+i,f_szDigital[7-i]);}//writetoDpRam0~DpRam7offor(i=0;i<8;0x10+i,//writetoDpRam0~DpRam7of}（3）LCD界面显示模void #ifndef//Lcd_DspHz24(50,10,BLUE,"英蓓特三星实验平台");BitmapViewTft16Bit_800480((UINT8T*)(g_ucBitmap));}void #ifndef//Lcd_DspHz24(50,10,BLUE,"三星实验平台"); }GlobalUINT16TKeyNo //KeyUINT16TKeyNo1;UINT16TKeyNo2;UINT8TKPRData; ReadDatafromtherowofkeypadUINT8Tf; 8LEDUINT8T unsignedcharf_zDigital[10]//0~unsignedcharf_Digital[1]UINT8Tb[8]={0,0,0,0,0,0,0,0}; UINT8Ts[8]={'','','','','','','',' intnOut=0xFF;intOut=0xF0;UINT8Tkeyscan(void)//Scanthe UINT8Ti,for(i=0;i<4;{Kddr=~(0x4<<i); //Giveonelistalowleverfor(j=0;j<5;j++)//Checktherow,ifhavelowlever,thatisonekeywas{KPRData=KPRAddr;if(!(KPRData&(0x2<<j))) KPRData=if(!(KPRData&(0x2<< //Avoid do{KPRData=while(!(KPRData&(0x2<<j)));//WaitthekeytobereleasedKeyNo=i<<8|j;KeyNo1=i<<8|j;KeyNo2=i<<8|return //Onekeywas}}}}return //Nokeywas}void UINT8Ti,j,t,m,n,p,q; {switch(KeyNo){case0x0001:for(i=0;i<8;i++){s[i]='';iic_write_8led(0x70,0x10+i,f_Digital[0]);g=0;k=0;}break;//按D8LEDcase0x0003:s[g++]='0';b[k++]=0;break;case0x0102:s[g++]='3';b[k++]=3;break;case0x0103:s[g++]='2';b[k++]=2;break;case0x0104:s[g++]='1';b[k++]=1;break;case0x0202:s[g++]='6';b[k++]=6;case0x0203:s[g++]='5';b[k++]=5;break;case0x0204:s[g++]='4';b[k++]=4;break;case0x0302:s[g++]='9';b[k++]=9;break;case0x0303:s[g++]='8';b[k++]=8;break;case0x0304:s[g++]='7';b[k++]=7;break;default:break;} n=b[k-1];iic_write_8led(0x70,0x10+m,f_zDigital[n]);8LED }if(KeyNo FUN //在LCD显示输入提示 {for(j=0,p=0;j<7-{ if(KeyNo1==0x0300) E退出排序 A确定中断排序操作 {s[i]=' f=1;g=0;iic_write_8led(0x70,0x10+i, 8LED} while} B while}}} while}} for(m=0;m<8;{n=b[7-m]iic_write_8led(0x70,0x10+m,f_zDigital[n]);}rCPLDLEDADDR=nOut&0xfe; //LEDrCPLDLEDADDR=Out| 五、实验小让数字排序在LCD和8LED
