EEPROM_Write

EEPROM_Write_Block

sub procedure EEPROM_Write(dim address as longint, dim data_ as word)

Description Writes data to specified 

address

.

Parameters - 

address

: address of the EEPROM memory location to be written. 

- 

data

: data to be written. 

Nothing.

Nothing.

dim wrAddr as longint

    eeData as word

  ...

  eeData = 0xAAAA

  wrAddr = 0x7FFC30

  EEPROM_Write(wrAddr, eeData)

Specified memory location will be erased before writing starts.

sub procedure EEPROM_Write_Block(dim address as longint, dim byref data_ as 

word[100])

Description Writes one EEPROM row (16 words block) of data. 
Parameters - 

address

: starting address of the EEPROM memory block to be written. 

- 

data

: data block to be written. 

Nothing.

It is the user’s responsibility to maintain proper address alignment. In this case, address has to be a 

multiply of 32, which is the size (in bytes) of one row of MCU’s EEPROM memory.

dim  wrAddr as longint

     data as string[16]

...

wrAddr = 0x7FFC20

data = “mikroElektronika”

EEPROM_Write_Block(wrAddr, data)

- Specified memory block will be erased before writing starts. 

- This  routine  is  not  applicable  to  the  24F04KA201  and  24F16KA102  family  of  MCUs,  due  to  the 

architecture specifics. 

Library Example

This project demonstrates usage of EEPROM library functions for dsPIC30F4013. Each EEPROM (16-bit) location can 

be written to individually, or in 16-word blocks, which is somewhat faster than the former. If Writing in blocks, EEPROM 

data start address must be a multiply of 16. Please read Help for more details on the library functions!
