This should again compile without problems. We finally need to configure a logging system - Hibernate uses commons logging and leaves you the choice between Log4j and JDK 1.4 logging. Most developers prefer Log4j: copy log4j.properties

Once relegated to the hinterlands of low cost indicatorlights, the LED is again in the spotlight of the lightingworld. LED lighting is now ubiquitous, from car headlightsto USB-powered lava lamps. Car headlights exemplifyapplications that capitalize on the LED’s clear advantages—unwavering high quality light output, tough-assteelrobustness, inherent high effi ciency—while a USBlava lamp exemplifi es applications where only LEDs work.Despite these clear advantages, their requirement forregulated voltage and current make LED driver circuitsmore complex than the venerable light bulb, but some newdevices are closing the gap. For instance, the LTM®8040μModule™ LED driver integrates all the driver circuitryinto a single package, allowing designers to refocus theirtime and effort on the details of lighting design criticalto a product’s success.

基于單片機(jī)的紅外門進(jìn)控制系統(tǒng)設(shè)計與制作:我們所做的創(chuàng)新實驗項目“基于單片機(jī)的紅外門控系統(tǒng)”已基本完成，現(xiàn)將其工作原理簡要說明。該系統(tǒng)主要分為兩大部分：一是紅外傳感器部分。二是單片機(jī)計數(shù)顯示控制部分?；倦娐穲D如下:其中紅外傳感器部分我們采用紅外對管實現(xiàn)，紅外對管平行放置，平常處于接收狀態(tài)，經(jīng)比較器輸出低電平，當(dāng)有人經(jīng)過時，紅外線被擋住，接收管接收不到紅外線，經(jīng)比較器輸出高電平。這樣，當(dāng)有人經(jīng)過時便會產(chǎn)生一個電平的跳變。單片機(jī)控制部分主要是通過外部兩個中斷判斷是否有人經(jīng)過，如果有人經(jīng)過，由于電平跳變的產(chǎn)生，進(jìn)入中斷服務(wù)程序，這里我們采用了兩對紅外傳感器接到兩個外部中斷口，中斷0作為入口，實現(xiàn)加1操作，中斷1作為出口，實現(xiàn)減1操作。另外，我們通過P0口控制室內(nèi)燈的亮暗，當(dāng)寄存器計數(shù)值為0時，熄燈，不為0時，燈亮。顯示部分，采用兩位數(shù)碼管動態(tài)顯示，如有必要，可以很方便的擴(kuò)展為四位計數(shù)。精益求精！在實驗過程中，我們走了非常多的彎路,做出來的東西根本不是自己想要的,我們本想做成室內(nèi)只有一個門的進(jìn)出計數(shù)，原理已清楚，即在門的兩邊放置兩對紅外對管，進(jìn)出時，擋住兩對對管的順序不同，因此，可判斷是進(jìn)入還是出去，從而實現(xiàn)加減計數(shù)，編程時，可分別在兩個中斷服務(wù)程序的入口置標(biāo)志位，根據(jù)標(biāo)志位判斷進(jìn)出，詳細(xì)內(nèi)容在程序部分。理論如此，但在實際過程中，還是發(fā)現(xiàn)實現(xiàn)不了上述功能，我們初步判定認(rèn)為是程序掌握得不夠好,相信隨著自己對單片機(jī)了解的深入,應(yīng)該會做出更好的 (因為我們是臨時學(xué)的單片機(jī)),程序的具體內(nèi)容如下： $MOD52 ORG 0000H LJMP MAIN ORG 0003H LJMP 0100H ORG 0013H LJMP 0150H ORG 0050HMAIN: CLR A MOV 30H , A ;初始化緩存區(qū) MOV 31H , A MOV 32H , A MOV 33H , A MOV R6 , A MOV R7 , A SETB EA SETB EX0 SETB EX1 SETB IT0 SETB IT1 SETB PX1NEXT1: ACALL HEXTOBCDD ;調(diào)用數(shù)制轉(zhuǎn)換子程序 ACALL DISPLAY ;調(diào)用顯示子程序 LJMP NEXT1 ORG 0100H ;中斷0服務(wù)程序 LCALL DELY mov 70h,#2 djnz 70h,next JBC F0,NEXT SETB F0 CLR P0.0 LCALL DELY0 SETB P0.0 MOV A , R7 ADD A , #1 MOV R7, A MOV A , R6 ADDC A , #0 MOV R6 , A CJNE R6 , #07H , NEXT CLR A MOV R6 , A MOV R7 , ANEXT: RETI ORG 0150H ;中斷1服務(wù)程序 LCALL DELY mov 70h,#2 djnz 70h,next2 JBC F0,NEXT2 SETB F0 CLR P0.0 LCALL DELY0 SETB P0.0 CLR C MOV A , R7 SUBB A , #1 MOV R7, A MOV A , R6 SUBB A , #0 MOV R6 , A CJNE R6 , #07H , NEXT2 CLR A MOV R6 , A MOV R7 , ANEXT2: RETI ORG 0200HHEXTOBCDD:MOV A , R6 ;由十六進(jìn)制轉(zhuǎn)化為十進(jìn)制 PUSH ACC MOV A , R7 PUSH ACC MOV A , R2 PUSH ACC CLR A MOV R3 , A MOV R4 , A MOV R5 , A MOV R2 , #10HHB3: MOV A , R7 ;將十六進(jìn)制中最高位移入進(jìn)位位中 RLC A MOV R7 , A MOV A , R6 RLC A MOV R6 , A MOV A , R5 ;每位數(shù)加上本身相當(dāng)于將這個數(shù)乘以2 ADDC A , R5 DA A MOV R5 , A MOV A , R4 ADDC A , R4 DA A ;十進(jìn)制調(diào)整 MOV R4 , A MOV A , R3 ADDC A , R3 DJNZ R2 , HB3 POP ACC MOV R2 , A POP ACC MOV R7 , A POP ACC MOV R6 , A RET ORG 0250HDISPLAY: MOV R0 , #30H MOV A , R5 ANL A , #0FH MOV @R0 , A MOV A , R5 SWAP A ANL A , #0FH INC R0 MOV @R0 , A MOV A , R4 ANL A , #0FH INC R0 MOV @R0 , A MOV A , R4 SWAP A ANL A , #0FH INC R0 MOV @R0 , A MOV R0 , #30H MOV R2 , #11111110Bagain: MOV A , R2 MOV P2 , A MOV A , @R0 MOV DPTR , #TAB MOVC A , @A+DPTR MOV P1 , A ACALL DELAY INC R0 MOV A , R2 RL A MOV R2 , A JB ACC.4 , again RETTAB: DB 03FH , 06H , 5BH , 4FH , 66H , 6DH , 7DH , 07H , 7FH , 6FH ;七段碼表DELY: MOV R1,#80D1: MOV R2,#100 DJNZ R2,$ DJNZ R1,D1 RET DELAY: MOV TMOD , #01H ;延時子程序 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 該系統(tǒng)實際應(yīng)用廣泛?？捎迷谏a(chǎn)線上產(chǎn)品數(shù)量統(tǒng)計、公交車智能計數(shù)問候（需添加語音芯片）、超市內(nèi)人數(shù)統(tǒng)計等公共場合。另外，添加串口通信部分便可實現(xiàn)與PC數(shù)據(jù)交換的功能。 由于，實驗簡化了，剩下不少零件和資金，所以我們又做了兩項其他的實驗。
