 		 #150549 - How would it be confusing?
Responding to: ???'s previous message
It is the standard way to approach any complex system - not just in electronics or software!

eg, a car is a very complex system, so we consider it as a number of simpler, easier-to-understand, subsystems - like engine, transmission, suspension, etc...

It's exactly the same here: if "code for AT89C2051+HD44XXX to display uart tx/rx" is too complex to figure-out in one go, then try it in small steps - such as:

  • uart tx/rx;

  • AT89C2051+HD44XXX (LCD)

    Ap Charles said:
    He knows what a UART is and how LCD is interfaced , no need to teach him that

    Exactly - that's why I asked the quesion, "where's the problem?"

    If he already has the UART part, and already has the LCD part, then he needs to ask a specific question if has has some specific difficulty in combining the two.
    Otherwise it is just "Gimme Code". Again.

    parallel LCD(HD type) for serial uart LCD display            01/01/70 00:00      
       What's the problem?            01/01/70 00:00      
          entirely irrelevant to this -- why?            01/01/70 00:00      
             They can be treated as 2 separate sub-systems            01/01/70 00:00      
                2 sub systems.. ohhh splitting :) remember!            01/01/70 00:00      
                   What are you on about            01/01/70 00:00      
                      I mean electrical interfaces            01/01/70 00:00      
             Look at it this way...            01/01/70 00:00      
                Thats your subjective understanding            01/01/70 00:00      
                   Ah, you got me there!            01/01/70 00:00      
                      God someone save me - I clearly explain it            01/01/70 00:00      
                         How would it be confusing?            01/01/70 00:00      
                            Nop you did this to him            01/01/70 00:00      
                               No, that was for you!            01/01/70 00:00      
                                  How did you make out that I want you to teach me            01/01/70 00:00      
                                     How could it be unnecessary?            01/01/70 00:00      
                                        And you started teaching me instead ? , Iam not OP            01/01/70 00:00      
                                           You were the one that couldn't see it            01/01/70 00:00      
                                              I can see that , you are reveiling a BIG secret            01/01/70 00:00      
                                                 thye irrelavancy is            01/01/70 00:00

                OK thank's            01/01/70 00:00      
                   Just build it            01/01/70 00:00      
                      Different between innovative and homemade            01/01/70 00:00      
                         You still haven't said what the problem is            01/01/70 00:00      
                         very expensive            01/01/70 00:00      
       but the question asked for code - not physical I/F            01/01/70 00:00      
          An ounce of work is better than pound of criticism            01/01/70 00:00
