i planned to do some daring 89c51 based projects, and so i bought a flash programmer, 2 89c51s, and numerous other electronic bits and pieces like capacitors, oscillators etc, that made me broke!
and when i pluged the prgrammed 89c51 in the bread board, forget making 7 segments work, i can't seem to get a simple freakin LED to blink!
take this program for example:
ORG 0000H
MOV P1,#00H
HERE: CPL P1.0
MOV R1,#0FFH
BACK2: MOV R0,#0FFH
BACK: DJNZ R0,BACK
DJNZ R1,BACK2
SJMP HERE
END,
when i insert the micricintroller in, and turn the supply on,
NOTHING'S BLOODY HAPPENING...
there could not be any wiring errors, i've checked the simple circuit 100s of times!
the flash programmer seems to be working fine, i've replaced the 8951 too....
could someone please tell me what the hell is going on? this is a lot of money thst's going to waste, please help me people!
