【正文】 和七段數(shù)碼管的使用；3. 掌握步進(jìn)電機(jī)的角度控制和測(cè)試方法。2. 系統(tǒng)設(shè)計(jì)說明 系統(tǒng)原理圖 總體設(shè)計(jì)本設(shè)計(jì)用50H~53H存儲(chǔ)單元存儲(chǔ)轉(zhuǎn)動(dòng)次數(shù)和轉(zhuǎn)動(dòng)角度，數(shù)碼管顯示只掃描此區(qū)域的；設(shè)置一個(gè)JISUAN子程序來計(jì)算轉(zhuǎn)動(dòng)所需要的角度需要的拍數(shù)，存第0組的R3寄存器里；用R2記錄步進(jìn)電機(jī)已執(zhí)行的拍數(shù)，每步進(jìn)一拍，R2自加1，比較R2與R3的值判斷是否完成一次設(shè)定角度轉(zhuǎn)動(dòng)；用R1記錄已完成的轉(zhuǎn)動(dòng)次數(shù)，每完成一次設(shè)定角度轉(zhuǎn)動(dòng)則R1自加1，比較R1與60H（MOV 60H,50H）的值判斷是否停止轉(zhuǎn)動(dòng)。程序如下：BUJIN: MOV 60H,50H MOV R2,00H。BUJIN子程序R00807060504030201步進(jìn)輸出值10H30H20H60H40H0C0H80H90HBUJIN2子程序R00001020304050607步進(jìn)輸出值90H80H0C0H40H60H20H30H10H程序如下：BUJIN2: MOV R2,00H。記錄set鍵按下的次數(shù) ACALL DIS AJMP STTKKEYSET: INC R4 ACALL DIS AJMP STTKKEYSTART: MOV A,R4 CLR C SUBB A,02 JC S1 CALL JISUAN CALL BUJIN ACALL DISS1: AJMP STTKDIS: PUSH ACC PUSH 00H PUSH 03H PUSH DPH PUSH DPL MOV DPTR,AA1 MOV A,50H MOVC A,A+DPTR MOV DPTR,7F00H MOVX DPTR,A MOV DPTR,7F01H MOV A,0FBH MOVX DPTR,A CALL DELAY MOV DPTR,AA1 MOV A,51H MOVC A,A+DPTR MOV DPTR,7F00H MOVX DPTR,A MOV DPTR,7F01H MOV A,0F7H MOVX DPTR,A CALL DELAY MOV DPTR,AA1 MOV A,52H MOVC A,A+DPTR MOV DPTR,7F00H MOVX DPTR,A MOV DPTR,7F01H MOV A,0EFH MOVX DPTR,A CALL DELAY MOV DPTR,AA1 MOV A,53H MOVC A,A+DPTR MOV DPTR,7F00H MOVX DPTR,A MOV DPTR,7F01H MOV A,0DFH MOVX DPTR,A CALL DELAY POP DPL POP DPH POP 03H POP 00H POP ACC RETBUF: PUSH 00H CJNE R4,01H,BUF1 MOV 40H,50H MOV 41H,51H MOV 42H,52H MOV 43H,53H MOV 53H,A MOV 52H,43H MOV 51H,42H MOV 50H,41HBUF1: POP 00H RETJISUAN: MOV A,R4 CLR C SUBB A,02
