$ sudo make install

By default it's installed in /opt/vdf

Uninstall

If you want to uninstall the application enter with your terminal in the folder that you downloaded and type:

$ sudo make uninstall

Usage

The use is very simple you just need your Vin, the Vout you desire and a file containing all the resistors you have.

$ vdf Vin Vout filename

Then the program will print the 5 best pairs of resistors with less error.

Arguments

--verbose            -v      Prints verbose info.
--help               -h      Displays the help page.
--version                    Displays the version message.

Resistor file

You enter the resistor you have using the resistor file, the format is as follows:

10,22,47,100,150,200,220,270,330,470,510,680,1000,2000,2200,3300,4700,5100...

You can name it wathever you want.

Example

Lets say you have Vin = 12v and you want Vout = 8v, you resistors are in my_resistors.txt:

$ vdf 12 8 my_resistors.txt

An example output can be:

Vin: 12.00
Vout: 8.00
R1: 1000        R2: 2000        Error: 0.0000%
R1: 5100        R2: 10000       Error: 0.6623%
R1: 3300        R2: 6800        Error: 0.9901%
R1: 4700        R2: 10000       Error: 2.0408%
R1: 2200        R2: 4700        Error: 2.1739%
