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.
"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?
