I'm using ide ver 4.068. I'm new for dspic.
Anyone help for writing data eeprom and reading data eeprom.
I'm using function value= read_eeprom(address)
and write_eeprom(address, value)
But it does not work.
Anyone has a code for this?
thank |

How about some compilable code, otherwise it could be anything. |

| I don't have any code. But you said something doesn't work, which implies you have written a program, try to compile it, and either get a compiler error or when burnt into your PIC the program doesn't work as you intended. |

There is no error for compile.
But when I simulate it eeprom doesn't change data. |

Download the PCD compiler manual.
http://www.ccsinfo.com/downloads/PCDReferenceManual.pdf
Look in this section on page 291 (page 303 in the Acrobat reader):
The manual says:
| Quote: |
write_eeprom (address, value)
Address is the 0 based starting location of the EEPROM write |
Note that you don't put in the physical address of the eeprom.
Just put in a relative address that starts at 0. For example, if you
have 1024 bytes of eeprom in the PIC, then you can use addresses
0 to 1023 (0 to 0x3FF in hex). |
