disabling a MAX16910 with a DS3234

this regulator uses 1.6 ua when it's disabled. enable regulator, enablepin must driven high. 
https://www.sparkfun.com/datasheets/breakoutboards/ds3234.pdf
the ds3234 can sleep, using 1.5ua it's coin cell battery.  want shut down project (atmega328 base of it), controlling max16910 regulator int pin ds3234.  ds3234 uses it's alarm trigger int pin go low, max16910's enable pin active high, startup regulator, have pull enable pin high.  possible have ds3234's int pin minimal components , quiescent current?

int open drain need pullup resistor there. enable has pulldown current of 0.65ua. seems have use pullup resistor wired int in. connect int enable.  pullup resistor value v(in)/1.5ua then..
it depends on logic of switching enable on/off, however. when regulator shall switched off when int high need inverter there (ie. n-channel mosfet , additional resistor).

dear all, working on image processing using raspberry pi, have installed intex usb web camera on raspberry pi. have used basic python script of image processing https://www.cl.cam.ac.uk/projects/raspb ... first.html required libraries installed on raspberry pi. script code: import imgproc imgproc import * # open webcam take pictures camera = camera(160, 120) # open viewer window display images viewer = viewer(160, 120, "the first step") # take picture camera img = camera.grabimage() # display image in viewer viewer.displayimage(img) # iterate on each pixel in image x in range(0, img.width): for y in range(0, img.height): # value @ xth column , yth row, place intensities variables red, green, blue = img[x, y] # test find colour dominant if red > green , red > blue: # red dominant, set pixel red img[x, y] = 255, 0, 0 elif green > red , green > blue: img[x, y] = 0, 255, 0 else: # if red or gr

i have laptop dead motherboard . can remove components laptop , in anyway possible connect raspberry pi inbuilt display , keyboard on laptop ? (and touchpad if possible). (i figured remove components inside , fix pie inside , use extended usb cable , connect available usb ports respective holes in laptop skeleton, same headphone out ) . i'm noob when comes pi . on topic appreciated if screen lvds type may possible use screen installing converter board. this: http://www.ebay.com/itm/hdmi-dvi-vga-dr ... 3027&rt=nc need model number of screen , ask seller if work. or search ebay using brand , model number. assuming screen in working order..... back-light not burnt out etc.. other devices...... can used if have usb interface not part of motherboard. have make connector. raspberrypi
