Created page with "= Action = Reads the content from the DATA EEPROM and stores it into a variable. Action =

Reads the content from the DATA EEPROM and stores it into a variable.

This statement is provided for backwards compatibility with BASCOM-8051.

You can also use the ERAM variable instead of READEEPROM :

 

Dim V as Eram Byte 'store in EEPROM

Dim B As Byte  'normal variable

B = 10

V = B   'store variable in EEPROM

B = V   'read from EEPROM

 

When you use the assignment version, the data types must be equal!

According to a data sheet from ATMEL, the first location in the EEPROM with address 0, can be overwritten during a reset so don't use it.

 

You may also use ERAM variables as indexes. Like :

Dim ar(10) as Eram Byte

 

When you omit the address label in consecutive reads, you must use a new READEEPROM statement. It will not work in a loop:

 

Readeeprom B , Label1

Print B

 

Do

Readeeprom B

Print B Loop

Until B = 5

 

This will not work since there is no pointer maintained. The way it will work :

 

ReadEEprom B , Label1 ' specify label

ReadEEPROM B ' read next address in EEPROM

ReadEEPROM B ' read next address in EEPROM

 

OR

 

Dim Next_Read as Integer

Dim In_byte as Byte

Dim Eerom_position as Integer

 

Eerom_position = 20                                  ' Set the start read point in eerom

For Next_Read = 1 To 5 Step 1                   ' Set up the bytes to be read from eeprom

Readeeprom In_byte , eeprom_position         ' Use a variable as the pointer to eeprom location

Call another_sub_routine                            '

Incr Chr_pos_font                                    ' Now set pointer for next eeprom data byte

Next

 

 

In the XMEGA, you need to set the mode to mapped : [[CONFIG EEPROM|CONFIG EEPROM]] = MAPPED.
