Thanks Petar for your reply, it does help also alot, but i would like to ask more question which is :
as i mentioned before, i need that circuit to take binary signal from sensor, on or off, and indicate both status, so can i connect the sensor binary signal output direct to the MAX1472 data pin, or i would need interface, if interface which type of IC's to use, comparator, or gate IC?, encoder?, as that what i still need to make sure of to be the whole circuit clear for me
will appreciate your reply,
Thanks
