Sleep mode not functionning

[lerameur]

Hi,

I am trying to use the sleep command (assembler way) with and without the LCD as shown in my code. Either way it does not seem to work because without the LCD I always get 22mA from my 12v batteries and with the LCd module about 85mA . Can someone tell me why the sleep command do not work.
I know I dont have any interrupt to get out of sleep, but first thing first
Thanks

I read in a post that I needed to chang the GIE in the INTCON register.. so I did with no luck:

INTCON.7 = 0 ' GIE = 1
INTCON.4 = 1
@ sleep

Hi, Ken

When talking about sleep mode current draw ...

a full scheme AND full code of the project are highly necessary ...

PS : I already bet 10 mA for your 12v/5v regulator ....
