I recently built a gate opener and programmed a 12F675 to control it via wireless remote. I have a 12v Sealed Lead Acid battery as power,
I've looked at many, many float charger circuits and decided to just program a PIC to close a relay which will allow a trickle charge to top off the battery every, say 100 to 150 hours for a period of about an hour or whatever is needed. (TBD)
I've tried Darrel's "Elapsed timer" but I can't get it to work in this application, "Ticks" seem to be seconds and "Seconds" seem to be minutes, not sure.
Anyway, can I just use multiple SLEEP commands of 65,535 seconds (18+ hours) to achieve the desired delay between charging pauses ?
Or, can anyone suggest a better method ?
Thanks for any advise
