help with write command
Hi everyone, Kind of new at this and I'm pulling my hair out. Here's the code I'm having trouble with
dtempset:
lcdout 254,1, "set Daytime Temp"
dtempset2:
lcdout 254,192, dec2 temp," Celsius"
if up = 1 then
temp = temp + 1
if temp > 45 then
temp = 45
endif
endif
if down = 1 then
temp = temp - 1
if temp < 1 then
temp = 1
endif
endif
pause 100
if enter = 1 then
write 13,temp
pause 20
gosub check
goto ntempset
endif
goto dtempset2
ntempset:
lcdout 254,1, "set Night Temp"
ntempset2:
lcdout 254,192, dec2 temp," Celcius"
if up = 1 then
temp = temp + 1
if temp > 45 then
temp = 45
endif
endif
if down = 1 then
temp = temp - 1
if temp < 1 then
temp = 1
endif
endif
pause 100
if enter = 1 then
write 14,temp
pause 20
gosub check:
goto dtempset
endif
goto dtempset2
check:
read 13,test
pause 20
read 14, test2
lcdout 254,1, dec test," ",dec test2
pause 5000
return
it seems that the value keeps being pushed into address 13 and over and not into 14???? I'm going crazy!

Hi,
Could your processor be a 18F ???

I have no hair to lost so maybe i could help. Can you post your whole code, PIC model, OSC speed here.
OH, please when you post a code use code tags
[code]
paste your code here
[/code]
this make it easier to read.
Maybe temp is a WORD variable?
<hr>
not sure how this would behave..
Never tested it but i see no reason to have colon here.. maybe Skimask see of some ;)

pic is a 16f628a 4meg crystal. whole program is very long and messy nearly up to 1600 bytes so I'm not sure if its a good idea to post. if I use an eeprom 13,[??,??] at they start it works fine but i just cannot put temp into 13 and 14. temp is also a byte

Any interrupt in your code somewhere?
Which version of the compiler?
paste your first code lines... those before the main.

:D oh well...this what might happen when you copy/paste your code block... but omit a single Label change... i don't know why i haven't saw at first... anyways, the problem is in your ntempset2 section
Code:
if enter = 1 then
write 14,temp
pause 100
gosub check
goto dtempset
endif
goto ntempset2
was dtempset2 before... hence why it never write @ 14... funny huh?

must of looked over that 100 times, thankyou mister e
