Hey Curry,
Acknowledgments are our motivation to assist
Basically the 18m2 reads an internal voltage reference adc when it detects the voltage dropping below 4v it sends a pulse of any length up to picaxe supply voltage which cuts off all loads including itself until some external reset is applied.
When the low voltage event occurs i need all loads including the picaxe that has triggered the event to be cutoff from the voltage source.
Just bear in mind, the controlling PICAXE must always have power (alternatively, u should design such that when in sleep mode, it should run from a battery e.g CR2025 button cell) while all the loads connected to it have been switched OFF.
Cutoff design illus:
By using FPF2116; u need just a PSU source; all the loads (Don't exceeds the current and capacitive loading specs) will be connected to the output of the device while only the controlling PICAXE is connected to the input side of FPF2116. Use the Latch feature of your 18M2 to apply a controlling signal to the control pin of FPF2116. A high to the control pin will switch ON power to all the loads while a load will switch OFF power to all the loads after which, u'll have to put 18M2 in sleep mode and when there is a signal to the reset pin, it gets out OFF sleep mode and do what ever u want.
U can't totally cut power OFF the controlling device! otherwise how will it monitor/control the loads connected to it. How will it react to an external reset if there is no power to it! Except you want to do that manually and hence there is no need for the flipping reset because flipping the power switch manually is same as resetting the entire circuit.
When the pixace has entered low power mode by using "end" are all outputs left untouched in their original state before the end command low/high ?
You can figure this out yourself by simulating your codes in PICAXE PE.
i.e write a simple program including
output pins and the
end command; run the program in manual mode and see what it does (monitor the
output pins states when the
end command is executed).
