A simple python binary calculator to use DMX Dip Switches

It can convert binary to decimal and vice versa.

A dip switch allows us to enter a DMX Address on our fixtures. Is a simple binary way to get any number. When a pin is ON it counts as a 1, when it is OFF it counts as a 0 (Activated or deactivated). For DMX is common to find dip switches that have 9 pins to address and another one that activates "auto mode".

Because each pin has a value when it is switch to ON position from 1 to 256 --> 1 2 4 8 16 32 64 128 256, we can get 511 different addresses with these 9 pins. Some brands use the 10th pin to set the number 512, but only when a channel can be used in that fixture, so it's no so common to find it in the wild.

How it works?

When the script runs, it asks us for what do you want to convert, from binary (positions of dipswitch pins) to decimal (number) or vice versa.

Pin Position (0) | Address (1)

If 0 is selected, write the positions of the pins as you see them in the dip switch, from 1 to 9 considering the ON position as a 1.

Position of Pins: 100100101

OUTPUT:

DMX Address: 329

Then, it repeats again the first prompt Pin Position (0) | Address (1) useful if you are changing several fixtures addresses.

If 1 is selected, write the address you want to assign to the dip switch.

DMX Address: 329

OUTPUT:

Powers of 2: [1, 8, 64, 256]

Pin Position: 100100101

'c' clear the screen on mac, ios, linux and android. This feature has sense using the for loop that allow us to get 50 addresses (useful when changing addresses on several fixtures at once).

Windows users must change "clear" for "cls": os.system("cls")
