Hi, Using at89c51 i want some data to copy from program memory to external Data memory.. without using memcopy()... any idea ?
Enough said Gosh...miracles DO happen.
Gosh...miracles DO happen. If you realized how ridiculous your statemet above is, now, THAT would be a miracle. Erik
If you realized how ridiculous your statemet above is, now, THAT would be a miracle. And where would we go from there? Why would it matter? To a stereotypicle forum alpha-nerd such as yourself, the goal is simply a daily victory. One doesn't have to read too many of these threads to realize this. BTW, the spelling error is intentional. I figured if nothing else, you could pick the reply apart based on that. (wait for it... wait for it...)
the goal is simply a daily victory I could not care less about a "victory". HOWEVER I do care about someone leading the novices astray with blatantly incorrect statements. Erik
I could not care less about a "victory". HOWEVER I do care about someone leading the novices astray with blatantly incorrect statements. Really? And what do you call this: should have read "inc P2" can not be used when a shadow register is in use and that statement is self-evident. The only thing "evident" about that is that you simply don't get the big picture...yet you're concerned about the novice. Unless you (pre)shadow P2 at ALL TIMES, you can't safely manipulate it and expect any other portion of the program to use it(namely interrupts), then restore it after said use is complete. I admit when I'm wrong. I did that earlier in the thread and have since tried to correct it, at your request to elaborate on the topic. Your problem is you're an incessant know-it-all and you've appointed yourself the role of forum warden. Heck, look at the recent thread directed BY NAME to someone else, yet who's the first person to chime in and pontificating their wisdom? You. If you're really concerned about the novices, you'd consider how many of them you drive away with your pompous attitude.
Unless you (pre)shadow P2 at ALL TIMES, you can't safely manipulate it and expect any other portion of the program to use it(namely interrupts), then restore it after said use is complete. absolutely correct. BUT THAT IS INO THE POINT The issue you brought up was INC P2. Which, as opposed to your statements can NOT be used when you shadow (the increment will be lost at next shadow to port copy). I wish you would discuss THIS instead of the relative merit of my posts, where I could not care less about your opinion. Erik
