Mission clarification

Power UP
Read EEPROM
Transfer value from EPROM to VAR

Press Button
VAR adds one to it's self
Display VAR on LCD
Write VAR to EEPROM
Wait for another Button press

This message will self destruct in.....

Hi mackrackit,

I've not been able able to look at the project this weekend due to a family issue.

Will be back 'on mission' tomorrow all being well.

Yup, family comes first. In the end that is all we got.

Hope things turn out well.

Never a truer word....

Hope things turn out well.

Thank you and they have I'm very relieved to say.

Back on the case tomorrow after a good nights sleep.

Hi mackrackit,

Things pretty much back to normal here (panic over)

So here's the first part of the brief, I think it covers these components:

Power UP: Read EEPROM: Transfer value from EPROM to VAR: Press Button:
VAR adds one to it's self: Display VAR on LCD

I didn't want to try and do any more just in case I'm wildly off track on this, what do you think? I've left out all the DEFINES for clarity.

Total var word        ' Data variable
B1      VAR     BYTE  'Stored DATA address
clear                 'Re_set volatile memory to zero (Not EEPROM?)

MAIN:
gosub Power_up        'On Power_up GOTO READ EEPROM subroutine
Start:
if PORTA.5 = 0  then  count_up: 'If button pressed start counting
IF PORTA.5 = 1  THEN     Start: 'If button not pressed loop until it is
    
Count_up:                 'Button has been pressed
let Total = Total + 1     'Add one to value of Total taken from EEPROM   
LCDOUT $FE,1              'Clear LCD
LCDOUT $FE,$C0,DEC Total  'Display Total on LCD
PAUSE 500
GOTO Start: 

Power_up:                 'Power_up subroutine
Read B1, Total.HIGHBYTE	  ' Read high byte
Read B1+1, Total.LOWBYTe  ' Read low byte  
LET Total = Total         'Set Total to value set in EEPROM Memory
return

Glad to hear things are back to normal.

A quick look and it looks OK, might want to add a WRITE to EEPROM routine though...
