Beginning with BinPy

Introduction

BinPy is a python library with the vision to virtualize electronics.
It gives an easy way to design circuits and test them. One of the best thing about BinPy is that it has no dependencies other than pure python. Currently it supports python2.

Getting started

You can install BinPy using pip or you can install it using the source code

Installing using pip

sudo pip install BinPy

Installing using source code

~$ git clone http://github.com/BinPy/BinPy -b master
~$ cd BinPy
~/BinPy$ python setup.py install

It will install the latest stable version.

To install the development version

~$ git clone http://github.com/BinPy/BinPy
~$ cd BinPy
~/BinPy$ python setup.py install

Using BinPy

BinPy gives you the power of virtual electronic components. You have all 7400 series ICs, several 4000 series ICs, Logic Gates, Adder, Subtractor, Multiplier, MUX(2:1, 4:1, 8:1, 16:1), Latch, DFlipFlop, Counter, Clock at your disposal.

Let's start our demo with making a small circuit to convert Gray Code numbers to BCD numbers.

From the above images:
 W = A
 X = NOT(A) AND B
 Y = (NOT(A) AND B AND NOT(C)) OR (NOT(B) AND C)
 Z = (NOT(A) AND B AND NOT(C) AND NOT(D)) OR (NOT(B) AND NOT(C) AND D) OR (B AND C AND D) OR (NOT(B) AND C AND NOT(D))

Implementing the converter using gates.

from BinPy import gates
input = []

def gray_2_bcd(input):
    A = input[0]
    B = input[1]
    C = input[2]
    D = input[3]
 
    W = A
    X = AND(NOT(A), B)
    Y = OR(AND(NOT(A), B, NOT(C)),
           AND(C, NOT(B))
           )
    Z = OR(AND(NOT(A), B, NOT(C), NOT(D)),
           AND(NOT(B), NOT(C), D),
           AND(B, C, D),
           AND(NOT(B), C, NOT(D))
           )
    output =  [W, X, Y, Z]
    return output

Next time we'll use 4000 Series ICs to implement the converter.
