=== Choose Components ===
In the "Choose Components" screen, a list is presented of each of the things that can be installed. In order to use the Discovery Power Supply with the WaveForms application, the Adept Runtime, WaveForms Runtime, and WaveForms Application are required.
  * The Adept Runtime allows WaveForms to communicate with the Analog Discovery 2, Analog Discovery, Analog Discovery Studio, Digital Discovery, Discovery Power Supply, and Electronics Explorer Board.
  * The WaveForms Runtime contains a library and device support files needed to run custom applications.
  * The WaveForms Application is the Digilent virtual instrumentation interface.
  * The WaveForms SDK is the software development kit for creating custom applications.
  * If you have an Analog Discovery Pro (ADP5250), make sure to check the box for the driver installation for the 5000 series driver.  If you do not have one, you can leave the box unchecked.

**Note:** //Even with all components selected, the WaveForms install does not take much hard drive space (<200MB). Digilent recommends that all components are installed.//

--> Installing WaveForms : Linux #
<WRAP group>
First, download the package for Adept. This program is required for WaveForms to connect to the Discovery Power Supply (DPS3340) and must be installed prior to installing WaveForms.\\
For systems using **.deb packages**, (Ubuntu, Fedora, etc), use the built-in package manager to install the Adept Runtime and then WaveForms - typically, a package manager can be opened by double-clicking on the file in question. \\

<WRAP group><WRAP column half>
=== Download Adept Runtime ===

  * Download the current version of [[software:adept:start|Adept Runtime]].
  * Make sure to select the version of the Adept install file that is the same as WaveForms. I used the 64 bit RPM for WaveForms so I will use the 64 bit RPM for Adept.

--> Install Files using command line #
Alternatively, use the following set of commands in the terminal to install the Adept Runtime and WaveForms from the downloaded packages:

<code>
sudo dpkg -i <path to Adept Runtime .deb file>
sudo dpkg -i <path to WaveForms .deb file>
sudo apt-get install -f
</code>
<--

For systems using **.rpm packages**, (Red Hat Linux, etc), use the following set of commands in the terminal to install the Adept Runtime and WaveForms from the downloaded packages:

<code>
sudo rpm -i <path to Adept Runtime .rpm file>
sudo rpm -i <path to WaveForms .rpm file>
</code>

If WaveForms has already been installed on the system, replace the "-i" flag passed to the rpm command with "-U" to upgrade the existing installation.

==== 3. Enable the Supplies  ====


This section walks through using the Discovery Power Supply (DPS3340) for the first time. We will use the +5V power supply to power an external device.  

--> Power Supply Setup #

<WRAP group><WRAP column half>
=== 1. ===
If you haven't yet, plug the included wall power supply into an outlet, then plug it into the Discovery Power Supply.
=== 2. ===
Plug the Discovery Power Supply into the computer via the USB cable.
=== 3. ===
Flip the power switch on the left side of the Discovery Power Supply to the On Position and wait for the Discovery Power Supply (DPS3340) to turn on.

<WRAP group><WRAP column half>
=== 4. ===
Plug in a set of banana plug connectors into the **Output 1** port on the front of the Discovery Power Supply. Please connect the red banana plug to the red connector on the Discovery Power Supply and the black banana plug to the black connector.  While theoretically you could use any color, keeping things the same will avoid confusion when working with your circuit.  Use the alligator clip or minigrabber clips to connect the power supply to your Device Under Test.

=== 5. ===
Launch the WaveForms application. Upon launch, WaveForms will automatically detect and connect to the Discovery Power Supply in the Device Manager. If the Discovery Power Supply is not connected to the host computer when WaveForms launches, plug in the device and turn it on, at which point it will appear in the Device Manager’s device list and can be selected.

If your device doesn't show up, you can click the **Auto Refresh** button to have WaveForms begin automatically refreshing the list of devices.

In WaveForms, open the //Supplies// instrument by clicking on the **Supplies** button in the instrument panel on the left side of the screen.  Set the voltage and current from the dropdown menu.  Turn *off* the +15V and -15V power supplies, since we only are hooking up the 5V supply.  Click Master Enable to turn the Power Supply on.
