#129700 - In response to Jon Responding to: ???'s previous message |
So I don't think that I fully understand what you're getting at because as I understand your suggestion, it doesn't work...
I want to get something like this: mov dptr, #myfifo + offset offset can be anything from 0-127. I don't see how moving a into @dptr and then inc dptr does this... The only solution I see with inc is to do something like mov dptr, #myfifo loop: inc dptr djnz offset, loop I don't like that solution because it's gross...if offset is 127, that means 127 loop itterations! Am I understanding your suggestion? I am a newbie so it's possible that just went over my head... Any other suggestions? Thanks! |
