Have a look here for how to use the sleep command in Swordfish. You must do this exactly as shown.

Thanks Audioguru.
After progressing with the transistor section I am contemplating putting the pic to SLEEP during daylight but Swordfish has no SLEEP command in its library that I could find.

Can you add assembler/machine code routines to Swordfish? - assuming you can, then it's simple to put it to sleep.

However, it's generally much more important to make sure everything else is 'switched off', and that orientations of transistors etc. mean there's no current used in the off state.

Using sleep can be VERY useful, it's a good idea to have a 32KHz clock crystal running on TMR1 - this uses almost no power, and you can wake the PIC up every second via TMR1 interrupts so it can check if it needs to be running yet. While 1 second sounds like it's wasting a lot of power, running a few microseconds once a second doesn't waste much power.

Another simple power saving technique is to use a lower clock speed, usually PIC's run vastly faster than you need, and you can drastically reduce consumption by running them slower - many modern PIC's allow you to adjust clock speed while it's running, so you can make savings on a dynamic basis. No need to get carried away though, as external devices (LED's etc.) will consume MUCH more than the PIC does.

Well, that answered that question!

Will look at suggestions AFTER I get this code working.
I have the ADC working in a test code and all is great
Have the candle flicker routine in another code.
Trying to get both to work together but they don't seem to want to play together.
Had compile issues until put the ADC routine in a sub but it doesn't seem to read the ADC on portA.0
the transistor is enabled all the time. Won't shut off.
Am thinking I have the portA.0 addressed wrong??
As for the SLEEP, will add it in AFTER I get parts A and B to play together.
NOTE parta =the candle routine works
partb (ADC) works by itself. Add the two together and it won't turn off with LIGHT on the cds.

[MrDEB]

going grocery shopping w/ wife and will redo something simpler just using delayms.
have laptop, will travel
have a feeling the interupt is messing with the ADC.

 

[MrDEB]

back at the same old code and determined that the TMR2_interupt is conflicting with the ADCON1.7
more research
wonder if I changed the ADC input to portA.1 seeing how the chip has more ADC inputs

 

[MrDEB]

Boy what a new day does to the mindset!!
I made a few changes on a similar code that started changing the LED colors so went back to my code in post #24
Asked myself why isn't the sub routine called BEFORE the interrupt??
INTERRUPT TMR2_Interrupt()
analog_on ()
' HIGH(Signal_Pin)
SAVE(0)

after adding this change the ADC works exceptionally well and the candles flicker nicely without changing colors. The ADC is really senesitive to ANY change in light conditions. Need to adjust.
Now to get the tin cans done and mounted for the Pic, cds and ON/OFF switch.
Will post a video when done. /
