hi
I have been playing around for a couple of hours now just turning on and off leds on a 16f628a with gcbibe the problem is that everytime i complile to hex the file dont change when programmed unless i save the file as another name
the programmer i use is velleman k8048 and pic prog
any ideas?

Hi

If you are using the PIC (Velleman PIC programmer) then you will need to re-open the hex file again each time with the newly compiled/modified one. The reason for this is that Velleman K8048 will hold on to the last used hex file so it will used last loaded hex in its memory unless a reload (file-open INHX8M Hex file) routine is performed again.

Hope this help!

God blesses!!!

Best regards,

hi
from problem i have had i have had to close programmer software and even save the file as new file name in gcbibe etc... and then open that hex in the pic programmer its a bit of a pain because cant overwrite files either

so gcbasic wont overwrite a hex???

Are you leaving the programming software open and then clicking Compile? If so, then the programmer software is possibly keeping the hex file open. If this is happening, then the OS won't let GCBASIC write to the file.

i spent hours playing with that and it seems ok at moment but i was closing programmer software lol lol
I ll keep my eye on it

ive got another question with Subs do i have to define/declare them as with other software
because i keep having a problem with this code Nice and easy code
WHICH wont compile

No need to declare/dimension subs.

You are trying to set a pin (i.e. an output) that has been declared an input.  You really don't need the line:

else pin18 = off

You could change the direction of the pin locally to output, then run some code. Just remember to set as input before reading the pin again.

You might want to debounce the switch also some number of ms, say:

debounce:
if pin18 On then
wait 20 ms 'adjust as necessary
If pin18 Off then goto debounce
led_1
end if

thank you for reply
i have only just been getting started using gcbasic and i have been looking around at other code examples but got stuck with on & off (iam trying to give up smoking at the moment so my brain is everywhere  lol lol)

i did put the 100 ms in for debounce but maybe it was to high ms
know dought i will be asking alot of questions in the next few weeks but i will try the help file first
Thank you
