 		 #136618 - What about the A0, A1... pins on the 24C04
Responding to: ???'s previous message

do not just willy-nilly copy the code and use it - you will learn NOTHING.


Exactly!

But when you are struggling for days, to have somebody's working code as a reference is a great help.

I dont know whether anyone pointed out this to you, since I did not go through all the threads, Have you hardwired the slave address lines on 24C04 correctly, this has to match with slave address in your code.

How To Write the Data to EEPROM (Seial)            01/01/70 00:00      
   Slow the i2c clock            01/01/70 00:00      
      Well i am using 12 MHz with 8051            01/01/70 00:00      
         Speed            01/01/70 00:00      
         this is upon you to determine            01/01/70 00:00      
   the poor developer's "logic analyzer"....            01/01/70 00:00      
   What happens in the real hardware?            01/01/70 00:00      
      writing IS broken - but in several ways            01/01/70 00:00      
         I I Sir, i will use spaces for next, :-)            01/01/70 00:00      
            delay for write plus the real error            01/01/70 00:00      
      Sir i'v used P1 to see that data is written or not            01/01/70 00:00      
         Order of magnitude!            01/01/70 00:00      
         is it 100kHz or 1000kHz?            01/01/70 00:00      
      I dont have osciloscop :-(            01/01/70 00:00      
   In real world the P1 is High,            01/01/70 00:00      
   Code Comments            01/01/70 00:00      
      again "I I SIR", well sir i have got your Point,            01/01/70 00:00      
         to Asif (and others)            01/01/70 00:00      
   I2C Part number ...            01/01/70 00:00      
   Even the NOPs and delay wont working            01/01/70 00:00      
   I have Codded this in C,But still not working :-(            01/01/70 00:00      
      not a good idea            01/01/70 00:00      
      Asif,s C Code for I2C            01/01/70 00:00      
         You missed the point            01/01/70 00:00      
            Point taken            01/01/70 00:00      
   are you sure they are IIC, not SMB            01/01/70 00:00      
      To be very Honest i dont know tha its IIC or SMB            01/01/70 00:00      
         try this            01/01/70 00:00      
   Have you looked here?            01/01/70 00:00      
      Working code...            01/01/70 00:00      
         advice to Asif            01/01/70 00:00      
            i know that i dont have to Copy Paste,, :-)            01/01/70 00:00      
               WoW i have EEPROM Programmer,            01/01/70 00:00      
                  is it working at all?            01/01/70 00:00      
            What about the A0, A1... pins on the 24C04            01/01/70 00:00      
   Well sir Here are Comparision of C and ASM(My Way)            01/01/70 00:00      
      I few I2C questions            01/01/70 00:00      
         it is not uncommon to list IIC addresses this way,            01/01/70 00:00      
            I was askin for schematics...            01/01/70 00:00      
               Here is the Schematics,            01/01/70 00:00      
                  Pardon??            01/01/70 00:00      
                     Well sir it means this ckt is Dummy            01/01/70 00:00      
                        OK            01/01/70 00:00      
                           Well i am straight forward programmer :-)            01/01/70 00:00      
                           Well the Hardware Circuit is Exactly same as it.            01/01/70 00:00      
                              Not at all!            01/01/70 00:00      
                     Recheck it Sir i have added labels, :-)            01/01/70 00:00      
                        but            01/01/70 00:00      
                        and blinkey?            01/01/70 00:00      
                           It really worked :-) MCu is stucked at ACK            01/01/70 00:00      
                              Stuck at ACK            01/01/70 00:00      
                              Stuck in no ACK            01/01/70 00:00      
                                 Sorry i havent understood, forgive my dumbness            01/01/70 00:00      
                                    Stuck in ACK (Reminds me of work)            01/01/70 00:00      
                                    Still Stuck?            01/01/70 00:00      
                                       Sir i am gonna use the Acknowledge polling tech:-)            01/01/70 00:00      
                                          one note            01/01/70 00:00      
                                             Nice note:-) but it Clocking was wrong,            01/01/70 00:00      
                                       Sir i am gonna use the Acknowledge polling tech:-)            01/01/70 00:00      
   Here is working Code, :-)            01/01/70 00:00      
      for your benefit and others            01/01/70 00:00      
         Havent Gotten your Idea ?            01/01/70 00:00

               true and untrue            01/01/70 00:00      
                  C Loops are not Perfect, agreed            01/01/70 00:00      
                  C timing loops            01/01/70 00:00      
                     then don't call it C            01/01/70 00:00
