关于IIC总线的一个程序，不知道那里错了，请教吧里大神将单片机内存30H到37H的内容写到24C02，50H为首地址的空间中，再读到单片机60H为首地址的内存中去。以下是程序，错了，检查不出来 ORG 0000H JMP MAIN ORG 0040H MAIN: SDA BIT P2.0 SCL BIT P2.1 MOV SP,#5FH CALL START MOV A,#0A0H CALL WRITEBYTE MOV A,#50H CALL WRITEBYTE MOV R0,#30H CALL WRITEDATA CALL STOP CALL DELAY10US CALL START MOV A,#0A0H CALL WRITEBYTE MOV A,#50H CALL WRITEBYTE MOV A,#0A1H CALL READDATA MOV R1,#60H CALL READDATA CALL STOP SJMP $ START: SETB SDA SETB SCL NOP NOP CLR SDA NOP NOP CLR SCL RET STOP: CLR SDA SETB SCL NOP NOP SETB SDA NOP NOP RET ASK: SETB SDA SETB SCL NOP NOP MOV C,SDA CLR SCL CLR C RET WRITEBYTE: PUSH 0 MOV 0,#8 WRITE: RLC A MOV SDA,C SETB SCL NOP NOP CLR SCL DJNZ 0,WRITE CALL ASK JC WRITEBYTE POP 0 RET WRITEDATA: PUSH 0 MOV 0,#8 WRITED: MOV A,@R0 CALL WRITEBYTE INC R0 DJNZ 0,WRITED POP 0 RET READBYTE: SETB SDA PUSH 0 MOV 0,#8 READ: SETB SCL NOP NOP MOV C,SDA RLC A CLR SCL NOP NOP DJNZ 0,READ POP 0 RET READDATA: PUSH 0 MOV 0,#8 READD: CALL READBYTE MOV @R1,A CLR SDA SETB SCL NOP NOP CLR SCL INC R1 DJNZ 0,READD SETB SDA SETB SCL NOP NOP CLR SCL POP 0 RET DELAY10US: NOP NOP NOP NOP NOP NOP NOP NOP RET END
