eeprom-endeeprom

Defines a object data structure in eeprom (Syntax 1) or a expression (Syntax 2+3) accessing the whole eeprom-memory. Ensure that you don't violete the structure boundary because this will overwrite the succeeding data. Syntax 1:

eeprom Identifier
- Data
endeeprom

Syntax 2:

eeprom.Method/Property = Expression

Syntax 3:

Result = eeprom.Method/Property

^Method (read only)^^^

Name	Description	Return Type
.ByteValue(offset)	Read Byte	byte
.WordValue(offset)	Read Word	word
.IntegerValue(offset)	Read Integer	integer
.LongValue(offset)	Read Long	long
.SingleValue(offset)	Read Single	single
.StringValue(offset,bytes)	Read String of certain length	string
.PString(offset)	Read Pascal-String (Start-Byte is the length)	string
.CString(offset)	Read C-String (Null terminated)	string
.Addr	Address of data structure in Flash	word
.SizeOf	Read Size in Byte of the object	byte

offset: Byte-Position within the structure starting at zero.
bytes: Number of Byte to read.

data storage

The directives for the storage of data within a data object.

.db - 8 Bit values incl. strings
.dw - 16 Bit values
.dt - 24 Bit values
.dl - 32 Bit values

Note
Accessing areas outside the object boundary is possible and not checked.

Example

dim a as byte
dim s as string
a=table1.ByteValue(4) ' Read Byte of tabele1+4, reszlt: 5
s=table1.CString(12)  ' Read C-String, result: "Hello"
table1.ByteValue(1)=7 ' Write Byte
table1.CString(0)="I am an eeprom-String"  'Write string
a=eeprom.ByteValue(4)   ' Read a Byte from eeprom memory
eeprom.ByteValue(4)     ' Write a Byte from eeprom memory
 
' Define Data Structure in eeprom
' Note:
' The compiler stores the eeprom-values and strings in the file *.eep.
' They must also be uploaded to the controller.
eeprom table1
  .db 1,2,3,4,5
  .dw &h4af1,&hcc55,12345
  .db "Hello",0
