Sorry, I know that I am disturbing and u all must be thinking that my IQ have dropped to "0", but if ur not given the specific residence no. and location of the person u know then how could u find out instead given a geographical map of the city. Sorry once more but see to it if u all can help me, because I really need some, for which I will be very much obliged and ever grateful. Thank you.
u ur u u u this is a forum, not a blasted cellphone! Erik PS if 'y' and 'u' is missing from your keyboard, get a new one
Unless you have some physical disability that impairs your use of the keyboard, please make the effort to type "you", "your", etc, in full. If you want "help", that implies that you are actually doing some work yourself, and require assistance with it. "Help" does not mean doing the whole job for you, and handing you the completed result on a plate! If you want someone to do the job for you, look in the Consultants Database - and be prepared to pay for the work! http://www.keil.com/condb/search.asp So, if you are actually going to do some of this by yourself, start by downloading and studying the application note from Atmel titled "Interfacing AT24CXX Serial EEPROMs with AT89CX051 MCU". You have been given the link at least twice before, but here it is again: http://www.atmel.com/dyn/products/app_notes.asp?family_id=647 For descriptions of the 8051 instructions, see the 80C51 family programmer's guide and instruction set - which is Chapter 2 of the so-called "bible" for the 8051: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_PROG_GUIDE_1.pdf
"Sorry, I know that I am disturbing and u all must be thinking that my IQ have dropped to "0", but if ur not given the specific residence no. and location of the person u know then how could u find out instead given a geographical map of the city." After coming back several times to reread that, I think I finally get it (I know, I'm old and feeble -- in mind as well as body). The 'u'/'ur' stuff is flat-out offensive, but that's not what I'm talking about. You still seem to want to have a pinpoint, dead-nuts on, exact solution to your specific problem rather than working through how to apply the solutions you have been given already. You not only want coordinates to where you need to go, you actually want somebody to carry you there, then stand behind you, put their hands on both sides of your head, take their fingers and pry open your eyelids and force you to stare at something that you probably still won't understand. If you disagree with my assessment, then tell us what is wrong with what we have already told you time and time again! Don't just say I need help over and over again. What the **** is wrong with the pointer you've been given (and there may be much wrong, but you're not saying). You refine it, we'll refine it. Or at least I'll give it one, (read 1) more try. After that, I'm done with it!
Thanks to all of you for your suggestions. I am not disagreeing that the link provided didn't worked out, actually it did a lot to understand the entire scenario. But I am worried about the fact that will a code written for AT89Cx051 work for AT89C51. What I genuinely believe that you all are experts where as I am somebody who have started from scratch, so the problem lies there. Any ways I think this time I have corrected my keyboard and the word help. Hope to discuss with some more problems in the coming minutes. Thank you
"But I am worried about the fact that will a code written for AT89Cx051 work for AT89C51." I asked you before what you believe to be the important differences between these devices with regard to their ability to handle I2C interfacing. Why in the world would you be worried?
"But I am worried about the fact that will a code written for AT89Cx051 work for AT89C51." So why didn't you just say that?? Instead, you just re-posted identical questions with no indication that you had even bothered to read other replies! You can quell the doubt by looking in the Datasheet - does the code rely on anything that is not in the AT89C51?
You can quell the doubt by looking in the Datasheet - does the code rely on anything that is not in the AT89C51? based on previous posts, I think I can guess the next post and answer it in advance: Q:where do I get a datasheet for AT89Cx051 A: There is no such chip. The explanation has already been given DO NOT ask for it again. Erik
Thanks Mr Erik Malund for your suggestion. I know that there is no such chip as 89Cx051 but 89C1051, 89C2051 and 89C4051.
Dear Sir, I am now using the demo version of Keil uVision-3 which I have downloaded from the site. Is there a way to simulate an LCD graphically in it. Please guide me of the detailed procedure to do it.
Now you're going to the opposite extreme - inserting unrelated questions in an existing thread! This time, you really should've started a new thread! You have read the uVision Getting Started guide, and worked through the example projects in it, haven't you...? There is an application note on LCD simulation - look in the 'Support' section. There is also a regular member of the forum who frequetly posts his own simulator - so try searching for "LCD Simulation", etc.
