WRITE data to EEPROM on PIC18F8621

[dschafer]

Has anyone had experiance using READ and WRITE on the 18F8621. Using READ I can read the values stored in the EEPROM but I cannot WRITE new values to the internal EEPROM. Why is this? It works on the 16F devices I used in the past.

I guess this is probably not spacific to this device and assume its due to the migration from 16f to 18f.

What version of PBP?

Show us the program that's failing you...

Its a long program, but what i'm trying to do using READ and WRITE is as follows:

'at the start of the program read these values from EEPROM and place in the variables'

Read 0, trip_amount[0]
Read 1, trip_amount[1]

'so far so good, this works as per usual'

If S1 = 1 Then
Read 0, temperary[0]
Read 1, temperary[1]
If (trip_amount[0] <> temperary[0]) OR (trip_amount[1] <> temperary[1]) Then
Write 0, trip_amount[0]
Write 1, trip_amount[1]
LCDOut $FE, 1
LCDOut $FE, $C0 , " SAVING CHANGES"
Pause 1000
EndIf
Goto Menue_2_0
EndIf

'I get a SAVING CHANGES on the LCD but the eeprom values dont change'

well that should work fine, must be something in the rest of the program that isn't being shown, maybe a variable declaration, changing the variable itself in another part of the program, etc.etc.
