writing a longword to eeprom

[hudyboy1]

Hi people!
Does anyone have any idea how to save longword to internal mega32 eeprom?
Please, heelp!

Hi,

Just break the longword into bytes and put each byte into consecutive locations in EEPROM.

Regards,
Filip.

That was my first response but I held off to see what other responses came but perhaps the chap dunno how to do the split

hudyboy1, if you need more help how to split the longword into bytes then please
ask

but perhaps the chap dunno how to do the split

Check user manual of mikroBasic for AVR.
On chapter 3, section "Built-In Routines" ... page 95++
Check : Lo(), Hi(), Higher(), Highest() functions

and if you can read french language, I remember we already discussed this stuff on mikroBasic for PIC forum long time ago http://www.mikroe.com/forum/viewtopic.p ... int+eeprom

Hi, perhaps this can help: http://www.rosseeld.be/DRO/PIC/EepromVariable.mpas

Hi guys!
Thanks for the effort, I was browsing a bit and found out two procedures (one for read, the other one for...you know what for ).
I had the idea with hi and lo,but I made an error when I tried to divide already divided (lo and hi) long word.
Tnx again! (and special thanks to Dany for writing and to Corallaro for posting:) )
Btw, here's the code:


Hi Guys

There is a conversion of beautful routine wrote by Dany for mikropascal

tested in mikrobasic 6 and mikrobasic PRO 2.50 to write/read word variable in EEprom of a 16f88 and it works perfectly...


Code: Select all
'------------------------------------------------------------------------------
'-------- Unit EepromVariable --- version: 2009-09-16 for Mikrobasic-----------
'------------------------------------------------------------------------------
'
'INTERFACE:

'procedure EEPromWriteVariable(Dat as ^byte, Number, EEpromAddress as byte)
'procedure EEPromReadVariable(Dat as ^byte, Number, EEpromAddress as byte)

'These procedures/functions do write and read the content
'of any type of variable to/from Eeprom.
'
' The procedures/functions need following parameters:
' - the address of the variable
' - the size of the variable (8–bit=1, 16-bit=2, 32-bit=4)
' - the first (lowest) address in Eeprom to write to or read from'
' Take care of the mapping of the variables in Eeprom so that they do not overlap!

'CALLING THE ROUTINES:

'EePromWriteVariable(@Variable, sizeof(Variable), EePromAddress)

'EePromReadVariable(@Variable, sizeof(Variable), EePromAddress)

'IMPLEMENTATION:

'sub procedure EePromWriteVariable(dim Dat as ^byte, dim Number, EEpromAddress as byte)
'dim I as byte
' for I = 0 to Number -1
' EEProm_Write(EEPromAddress, Dat^)' // write the "I"th byte
' Delay_ms(25)
' Inc(Dat)
' Inc(EEpromAddress)
' next I
'end sub

'sub procedure EePromReadVariable(dim Dat as ^byte, dim Number, EEpromAddress as byte)
' dim I as byte
' for I = 0 to Number -1
' Dat^ = EEProm_Read(EEPromAddress)' // read the "I"th byte
' Delay_ms(25)
' Inc(Dat)
' Inc(EEpromAddress)
' next I
'end sub

'EXAMPLE:

'dim CurrentValue as word
'dim StoredValue as word

'CurrentValue = 1023
'EePromWriteVariable(@CurrentValue, 2, 10)
'Delay_us(500)

'EePromReadVariable(@StoredValue, 2, 10)
'Delay_us(500)
'WordToStr(StoredValue, Text)
'Lcd_Out(1, 1, Text)

'So in LCD display you view "1023"
