what if i want to read and write a lot of data to serial eeprom ?? Sugiarso, if you use 24c512 then you have only 512/8=64 KB mem location to reading or writing. you can change the code easily to: mov dptr,#0fffeh ;instead of mov adres,#0ffh mov dyta,#19h lcall eeprom_write Therefore you must change [adres to dptr] in eeprom_write and eeprom_read routines. if i want to read and write data that not in the first address what should i do? it is easy,you should set read or write address in any accurate location only! for example at first of your code you can write: mov adres,#43h mov dyta,#22h lcall eeprom_write where should i asked the data address (not the eeprom address) thanks before I can't understand your aim from this sentence please describe it more Mehdi |
