#120657 - shall I spoil the fun? Responding to: ???'s previous message |
Erik said:
check_row: clr ROW0
setb ROW1
setb ROW2
setb ROW3
mov a,p1
anl a,#00001111b
cjne a,#00001111b,row_0will always be not equal, look at it again. Ashwin changed it to: check_row: clr ROW0
setb ROW1
setb ROW2
setb ROW3
mov a,p1
anl a,#01111111b ;test row zero
cjne a,#01111111b,row_0
But it still will always be not equal! I don't want to spoil the fun - and also the "morale", which follows from it. Just one more hint, again Erik said it first, try to run it in a simulator, you will see the problem immediately. An Andy has a point, too (with the spaces in db ' 0 '). JW PS. This is THE example of programmer's blindness. Try to explain how it works to your wife, friend, teddy bear... |
