editing a AT89C52

[vinstein]

Hello,
i got a project from my seniors which use AT89c52 & 2x16 LCD,the c program displays their names in LCD , ive edited the program to change names, but couldnt compile because of the missing header files TIMER.h & Lcd.h.... can anyone get the correct header for the program & simulate it???? thnx in advance

There are probably thousands of files out there named lcd.h and timer.h, many of which are for the AT89c52. I know I have a lcd.h which I wrote myself, the file you would be looking for is a file that these "seniors" either wrote or a file that came with some development board you're using, or even possibly with whatever compiler you're using. We don't know any of the above information as you haven't supplied it. Don't even know what simulator you're trying to use either.

hmm..
i thought thr'll b some common headers available for an AT89C52
thnx for d reply...

k.. anywayz to stop their names appearing ther by using some extrenal components(like some timing devices to the lcd pins) ??? n continue wit the rest of LCD operation???

 

[Norlin]

Sorry, I don't understand your question. What do you mean by "stop their names appearing"?
Also, your first post was pretty decent with the English used, however your second post was barely decipherable for me.

Sounds like he's trying to take credit for somone elses project.

hey i paid them for tat project !!!!! ,(they got the same from a PROJECT CENTER n those people wont give headers)

the LCD displays 4 names after a certain delay... i just want to change the names(for tat a program is necessary,but i dont have the headers),so anyother ways to do it

Ah so it's ok to pay people to do your homework.

use a binary editor and adjust the hex code.
