power Off/shutdown code/circuit

[DynamoBen]

In what way is it not reliable?

BTW you could replace:

FOR I=1 to 1000 'start a loop to die until DC power is disappears
Pause 1000
NEXT I


With:

End

More detail and a schematic will help. PIC# too

"PORTA.0=1 ' relay is ON", Isn't PORTA.0=0 ' relay is ON?

Hi,

Try to disable the Brown-out reset circuit.



Best regards,

My initial routine is not reliable because I guess the following happens:
1) turn on relay
2) do the job
3) turn off relay -> no AC power is applied
4) the large 2000 uF capacity voltage goes down slowly, i.e below 4V
5) the brown out logic kicks in -> resets the PIC which restarts from begining
6) goto 1) --> AC power is applied again...

will try the END statement as suggested above, otherwise will look at the LM2914 power regulator described in an other post.

Thanks
Eric

Hi,

Describe the electrical circuit used to turn on the device.
(Push button)?

Best regards,
