Hi,Dear sir; I want to write a program to modify the data in EEPROM IC by controlling the MCU via RS232 interface from the PC. Do you have any application notes on this subject? And any example codes? The MCU I am using is AT89C51 by Atmel Corp. Thanks in advance.
Are you talking about an external eeprom? Do you just want to change the data in x-data segmant or do you want to do something liek a software update, that means switching that eeprom back to code segment and let the modified program being executed?
Hi, Thank u for your reply.I want to modify the external EEPROM,which is AT93C46(by Atmel Corp.)Only to update the data via PC,and then send command(by MCU)to another controller to reset the system.How can I do it with the Hyper Terminal? Thanks in advance.
hello, i've seen ur post on KEIL's website in that u've specified that u'r working on AT93c46 eeprom & AT89c51 controller. I m also working on the same. my aaplication includes writting/reading the data into 93c46 memory using 89c51. but currently i m unable to write the data. do u have any code? it'll be a great help for me if u send the code. waiting for reply.thanks
u ur u've u'r u u What is that, Urdu? Definitely not English. I'll gladly help, but to do so, I must be able to understand the post. Erik
Sir, Thanx for the reply. that is not urdu, it is english only. actually i've written 'you' in short as 'u' and your as ur sorry for inconvinience.
"actually i've written 'you' in short as 'u' and your as ur" Why have you done that? It makes it hard to understand what you've written.
