I am using AT89c51. I have a project to get date from Rs232 and store on ROM. I dont know how to do this with Keil. If any one could help me. thanks in advance.
"I have a project to get date from Rs232 and store on ROM. I dont know how to do this with Keil" You cannot do it at all. With anything. Period. ROM = Read-Only Memory "Read-Only" means No Write. You cannot write to Read-Only Memory (ROM) - that's why it's called Read-Only "If any one could help me" They can't - it's impossible. Unless you meant PROM, or EPROM, of course...
Thanks I u dont know the solution why u r waisting others time. Matter is that u understude what i was aking. By the way PROM , EPROM And EEPROM all are addition of ROM, Ok my dear genious person.
"By the way PROM , EPROM And EEPROM all are addition of ROM" Yes - and the important addition is the 'P' for "Programmable" If you just have ROM with no 'P' then you cannot program it! "Matter is that u understude what i was aking." No, I don't - your question is too vague to answer. Exactly what sort of external memory are you talking about: parallel UV-EPROM? parallel Flash EPROM? serial EEPROM? something else?
"I u dont know the solution why u r waisting others time." Don't use SMS abbreviations if you want to be taken seriously. We do not wish to waste our time decoding them. "Matter is that u understude what i was aking." Your question is hopelessly vague. Explain what problem you are actually having.
