The system USES the MSC 51 series microcontroller AT89C52 as the core device for data acquisition system design, through the AT89C52 control ADC0809 conversion of signal from analog to digital, and then the data feedback to AT89C52 to collect , at the same time, AT89C52 control LED digital tube display the simulation voltage values. This system of low cost, practical strong, and easy to use.Key words Data Acquisition Single Chip Microputer Design 27附錄一 系統(tǒng)源程序源程序：＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊主程序＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊includedefine uchar unsigned chardefine uint unsigned intuchar code dispbitcode[]={0xef,0xf7,0xfb,0xfd,0xfe}。uchar code dispcode[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x00}。uchar dispbuf[5]={0,0,0,0,0}。uchar getdata,data2,data3,data4。uint R,datachanl,t1,y,flag。sbit dula=P1^7。sbit wela=P1^6。sbit ST=P1^0。sbit OE=P1^1。sbit EOC=P1^2。28sbit S1=P3^7。sbit S2=P3^6。sbit AA=P1^3。sbit BB=P1^4。sbit CC=P1^5。void start()。void choosechanl()。void adc0809()。void init()。void delay(uint z)。void desplay(uchar,uchar,uchar,uchar,uchar)。＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊主函數(shù)＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊void main(){init()。 //程序初始化 while(1) {29choosechanl()。start()。//啟動 AD 轉(zhuǎn)換函數(shù)choosechanl()。//通道選擇函數(shù)switch(R) {case 0:{AA=0。BB=0。CC=0。break。}。case 1:{AA=1。BB=0。CC=0。break。}。case 2:{AA=0。BB=1。CC=0。break。}。case 3:{AA=1。BB=1。CC=0。break。}。case 4:{AA=0。BB=0。CC=1。break。}。case 5:{AA=1。BB=0。CC=1。break。}。case 6:{AA=0。BB=1。CC=1。break。}。case 7:{AA=1。BB=1。CC=1。break。}。 }datachanl=R。if(flag==1){30adc0809()。//AD 轉(zhuǎn)換函數(shù) }getdata=getdata*500/255。data2=getdata/100。data3=getdata/10%10。data4=getdata%10。desplay(datachanl,0,data2,data3,data4)。}} ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊初始化程序＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊void init(){ R=0。 flag=0。 P1=0x04。//IN0}＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊通道選擇程序31＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊void choosechanl(){ if(S1==0) { delay(5)。//按鍵消抖 if(S1==0) { while(!S1)。 R++。 if(R==8) { R=0。 } } } } 32＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊啟動 AD轉(zhuǎn)換程序＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊void start(){ if(S2==0) { delay(5)。 if(S2==0) { while(!S2)。 {flag=1。} } } }＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊AD轉(zhuǎn)換程序＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊33void adc0809(){ ST=0。ST=1。ST=0。while(!EOC)。//等待轉(zhuǎn)換完畢OE=1。getdata=P2。//取轉(zhuǎn)換數(shù)據(jù)OE=0。flag=0。}＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊數(shù)碼管顯示程序＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊void desplay(uchar a,uchar b,uchar c,uchar d,uchar e){dula=1。P0=dispcode[a]。dula=0。34P0=0xff。 wela=1。P0=0xef。wela=0。delay(5)。dula=1。P0=dispcode[b]。dula=0。P0=0xff。wela=1。P0=0xf7。wela=0。delay(5)。dula=1。P0=dispcode[c]|0x80。dula=0。P0=0xff。35wela=1。P0=0xfb。wela=0。delay(5)。dula=1。P0=dispcode[d]。dula=0。P0=0xff。wela=1。P0=0xfd。wela=0。delay(5)。dula=1。P0=dispcode[e]。dula=0。P0=0xff。wela=1。36P0=0xfe。wela=0。delay(5)。} ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊延時程序＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊void delay(uint z){ uint t1,y。 for(t1=z。t10。t1) for(y=110。y0。y)。}
