anybody there knows how to design a calculator????
my project here is to design a 2 seven segment display LED using a hexadecimal matrix design...the problem is i dont know how...the design should have a primary encoder to determine which number will appear if u happen to pressed 2 keys....then i need to design a 2 memory segment for the 2 seven segment display...........and the design must be all in LOGIC CIRCUITS......THE SIMPLEST DESIGN THE BETTER
I think the easiest way to design a calculator is to buy a calculator!!
Myself, I've often wondered about that. It should use so many chips and so many memory elements: adders, integrators...My God!
So that put me off. These chips might even be difficult to find and if you should opt for discrete components, I wouldn't tell you you're going to end up with a ridiculously complicated & bulky circuit.
Hey, that's just my idea. Luckily someone would guide you to a schematc. :wink:
