 		 #163946 - Forum rules...
Responding to: ???'s previous message
Per said:
Why do you think it was suggested that he "first do this and then do that"? There are things you do someone to do in sequence, not because you like to control their life, but because there are big advantages of doing things in a certain order.

Per, you suggested him things he might not have the time or ability to do so. He asked for help and not for a basic course in "whatsoever". That's what I wanted to say. As we do not know where the "pain" of original poster is, we cannot begin a basics course each time, even if this would make sense. Again, this is no school. We do not have any responsibility for the original poster. If he asks for help in a final year project two days before the headline, then it's on him how he solves his problems.

Again, this is a forum, where we discuss, talk and have fun. Everyone can rise his question and everyone can enter into the discussion. Nobody is forced to give feedback or anything else. Well, if he is smart he will answer all questions in full detail, because then the chance of receiving good answers is very high.

Per said:
I have very much the right to request more information, if I find that there is too little information available to be able to help. Are you suggesting that I should lie and invent random help instead? Or do you think requesters are better helped by just being ignored? Rethink your view of how a forum works.

The forum rules says:

If you feel the person asking the question hasn't spent enough time reading documentation, either ignore the question or vote it as "Didn't Search First."

Did you read the word ignore? Yes, it's intended to ignore the original poster if he doesn't give enough feedback.

Per said:
Yes, there are situations where I buy help because of time or complexity constraints. But there has never been situations where I have bought help with school work. Do you think I should have?

Why all these attitudes, Per? Can't you rise a clear question? By the way, do you know what "project work" is? Here, a group of students have to do a project and are graded as group, which means that each one of the group gets the same grade, even if someone was especially lazy...

Per said:
But if it isn't relevant to this thread, then maybe you shouldn't use it as an argument.

Why did you interfere in a reply to Andy?? Why do you assume to be meant, when I talk with Andy??

Per said:
Your misunderstanding here is that you think a person can be helped if people on the forum do not step in and ask questions - (your very disliked requesting more information).

The only thing I dislike is, that you think you have the right to "request", Per. You have the right to "ask", but not to "request". Remember the forum rule, if you dislike someone's "performance", then please ignore him.

Scrolling Message in LED Display with 8051??            01/01/70 00:00      
   2 separate problems            01/01/70 00:00      
   the simple way            01/01/70 00:00      
      didnot get you            01/01/70 00:00      
         Standard circular buffer            01/01/70 00:00      
            Thanks            01/01/70 00:00      
               Flickering in scrolling            01/01/70 00:00      
                  Clip to viewport            01/01/70 00:00      
                     Testing on 8x8 display.            01/01/70 00:00      
                        Write fastest loop and count instructions            01/01/70 00:00      
                           Any other suggestions            01/01/70 00:00      
                              yes and no            01/01/70 00:00      
                                 Frankly speaking            01/01/70 00:00      
                                    time, time, time            01/01/70 00:00      
                              You should investigate old-style monochrome video adapters            01/01/70 00:00      
                                 but pretty close            01/01/70 00:00      
                                    not wishing to start a debate ...            01/01/70 00:00      
                                       pixel rate            01/01/70 00:00      
                                          Yes, that's true, but it's irrelevant            01/01/70 00:00      
                                             Persistence matters, and algorithm            01/01/70 00:00      
                                                I believe there's a difference in approach here            01/01/70 00:00      
                                                   Shift registers to drive rows, not columns.            01/01/70 00:00      
                                                      ...which is why they don'tfit this sort of application            01/01/70 00:00      
                                                         Think about pulse quota when multiplexing            01/01/70 00:00      
                                                            Yes, the multiplexing affects ultimate brightness ...            01/01/70 00:00      
                                                               never heard of 2 lines???            01/01/70 00:00      
                                                                  Yes, but most people can only read one at a time            01/01/70 00:00      
                                                                     16 pix            01/01/70 00:00      
                                                                        It's news to me ...            01/01/70 00:00      
                                                                           Good with forums            01/01/70 00:00      
                                                      Do you mean a REGISTERED shift register?            01/01/70 00:00      
                                                         Yes            01/01/70 00:00      
                                                            Absolutely!            01/01/70 00:00      
                                                         never seen one            01/01/70 00:00      
                                                      That's the answer i was looking for...            01/01/70 00:00      
                                       one can change the colour on an LED            01/01/70 00:00      
                                       a monochrome display has one LED per pixel            01/01/70 00:00      
                                          It is seldom so simple as one would like            01/01/70 00:00      
                                             I too read 8x8 as pixels/LEDs. However, probelm with scroll            01/01/70 00:00      
                                                Please leave that CRT            01/01/70 00:00      
                                                   But we area focused            01/01/70 00:00      
                                                   Chequebook time!            01/01/70 00:00      
                                                   You haven't told us anything useable!            01/01/70 00:00

                                                            re the rating of "Quoting Andy on this"            01/01/70 00:00      
                                                               LOL            01/01/70 00:00      
                                                                  It was me, Per...            01/01/70 00:00      
                                                                     Feedback            01/01/70 00:00      
                                                                        I agree with you in all points, but...            01/01/70 00:00      
                                                                           I agree, Kai --- in most cases ...            01/01/70 00:00      
                                                                              Kick-starting threads do require some form of pushing            01/01/70 00:00      
                                                         That will be UGLY            01/01/70 00:00      
                                                            Not necessarily...            01/01/70 00:00      
                                                         That is not ALL the information.            01/01/70 00:00      
            Looked at circular buffer yet?            01/01/70 00:00      
   Has anyone looked at Allegro?            01/01/70 00:00      
      A specific chip for the shift-register solution            01/01/70 00:00      
         Think about total power loss            01/01/70 00:00      
            you tell me            01/01/70 00:00      
      the A6833 and similar offerings            01/01/70 00:00      
   Code, problem, information and schematic.            01/01/70 00:00      
      BU4094 is fast enough, but...            01/01/70 00:00      
         look at 74HC595            01/01/70 00:00      
            Yes, and not to forget the 74HC4094...            01/01/70 00:00      
               and 80 resistors            01/01/70 00:00      
                  Mickey Mousing?? Availibility!            01/01/70 00:00      
                     my absolute impression ...            01/01/70 00:00      
                        Almost total silence            01/01/70 00:00      
                           ??            01/01/70 00:00      
                              How to activate Aamir?            01/01/70 00:00      
                                 I don't want to activate Aamir!            01/01/70 00:00      
                                    Yes, most comments here are free-running without the OP            01/01/70 00:00      
                                       Maybe the wrong sorts of questions were asked            01/01/70 00:00      
                        Let's see what the O/P wants to do            01/01/70 00:00      
                           with the amount of effort the OP shows ....            01/01/70 00:00      
                              What you have failed to consider ...            01/01/70 00:00      
                                 did you read            01/01/70 00:00      
                                    Yes, I did!            01/01/70 00:00      
                        And my absolute impression is...            01/01/70 00:00      
                           why should I do that?            01/01/70 00:00      
                              I have to agree            01/01/70 00:00      
                  What does it cost? How many would be needed?            01/01/70 00:00      
                     Exactly!            01/01/70 00:00      
                     ST2221 EQUIVALENT            01/01/70 00:00      
                        It's not widely available in the developing world            01/01/70 00:00      
                           Max power loss at high ambient temperatures            01/01/70 00:00      
                              Interesting point ... but ...            01/01/70 00:00      
                                 8- or 16-bit drivers for different applications            01/01/70 00:00      
                           because            01/01/70 00:00      
                              Is this a chicken and egg sort of question?            01/01/70 00:00      
                                 Different chips for different problems            01/01/70 00:00      
                                 no, applea and oranges            01/01/70 00:00      
                                    Isn't that a design parameter?            01/01/70 00:00      
                                       Physics and practical realities            01/01/70 00:00      
                                          In some cases, perhaps LED's are not the right technology            01/01/70 00:00      
                                       and what does all that to do with ....            01/01/70 00:00      
                                          They have to remain within specified limits.            01/01/70 00:00      
                                             Still missing muxed concept            01/01/70 00:00      
                                                No ... I'm not missing the concept ...            01/01/70 00:00      
                                                   yes you are            01/01/70 00:00      
                                                      You're thinking too narrowly, methinks.            01/01/70 00:00      
                                                         no, you are muddling            01/01/70 00:00      
                                                            It's just another way to manage a big sign            01/01/70 00:00      
                                                               not so, back at ya            01/01/70 00:00      
                                                                  PWM or shorter on times.            01/01/70 00:00      
                                                                  There's more than one way to skin a cat            01/01/70 00:00      
                                                                     Start producing signs.            01/01/70 00:00      
                                                                        Those arguments are weak!            01/01/70 00:00      
                                                                           not for those that have an inkling of understanding            01/01/70 00:00      
                                                                              So ... how fast can you clock 'em?            01/01/70 00:00      
                                                                                 if you had read and not muddled....            01/01/70 00:00      
                                                                                    Not Bad ! That IS a lot more reasonable!            01/01/70 00:00      
                                                                                       why on earth would you want to do that            01/01/70 00:00      
                                                                                          If a little bit is good, sometimes more is better ...            01/01/70 00:00      
                                                                                             you might, I wouldn't            01/01/70 00:00      
                                                                                                I can envision such a thing ... but I don't build signs            01/01/70 00:00      
                                                                                                   I feel the need to SHOUT            01/01/70 00:00      
                                                                                                      Time to get back to scrolling            01/01/70 00:00      
                                                                                                         as long as the CC drives one pixel            01/01/70 00:00      
                                                                                                            Don't everyone love a DC-driven sign?            01/01/70 00:00      
                                                                                                               In the interest of discussion ...            01/01/70 00:00

                                                                                                                           It comes down to why this is being discussed            01/01/70 00:00      
                                                                                                                              Where is the progress?            01/01/70 00:00

                                                                                                               I do not think so            01/01/70 00:00      
                                                                        One other thing ...            01/01/70 00:00      
                                                                     THAT IS what PWM does            01/01/70 00:00      
                                                                        For that, you don't need dedicated hardware            01/01/70 00:00      
                                                                           never said so            01/01/70 00:00

      why this complex, why so enamored by darlingtons?            01/01/70 00:00      
         Of course, your Allegro thingis would perfectly fit...            01/01/70 00:00      
            not the transistors, the ULN in the columns            01/01/70 00:00

            Yes, unless high cathode currents...            01/01/70 00:00      
               If he's sinking current from, at most, 16 cathodes ...            01/01/70 00:00      
                  Not 16 at a time. 0 or 1 for column. 0..80 for row            01/01/70 00:00

            "Drive-by-shooters"? Are you cuckoo??            01/01/70 00:00      
               I think that was the basic problem            01/01/70 00:00      
                  Yes, and as we do not know the state of knowledge...            01/01/70 00:00      
                     Once more you focus on bowing and other nonsense            01/01/70 00:00

                                    But that's it, Richard!            01/01/70 00:00      
                                       You're right, Kai, but not in the way that you might think            01/01/70 00:00      
                                 Can't see "not helped"            01/01/70 00:00

                                                                                 Yes, it looks like part of the assignment spec            01/01/70 00:00      
                                                                                    Assignment specs? Hardly...            01/01/70 00:00

                                                                                                   Probably yet another language problem            01/01/70 00:00      
                                                                                                      The O/P has a part to play, as do we of 8052.COM            01/01/70 00:00      
                                                                                                      Yes            01/01/70 00:00

                                                            Not big-bang solution, but snippet of code!            01/01/70 00:00      
                                                I'm not the only one who confuses things...            01/01/70 00:00      
                                                   Yes, language barrier            01/01/70 00:00
