Mounting the shield
MOUNTING THE SHIELD
Before starting up your Raspberry Pi, make sure that the VM205 shield is attached. If you attach the shield while the
Raspberry Pi is already running, it may reset the board, causing an unwanted reboot.

Installing Raspbian
INSTALLING RASPBIAN
Now you will need an empty formatted SD card on which to install Raspbian using the NOOBS installer.
Some shops sell SD cards that already have NOOBS preinstalled.
More information about NOOBS and the installation process can be found on the Raspberry Pi website.
Follow these installation instructions. Make sure to use the latest version of NOOBS available on their website.
http://www.raspberrypi.org/help/noobs-setup/
IMPORTANT: After the installation process, during your fi rst boot, you will boot into the Raspbian confi guration menu.
Here, you need to select Advanced Options, and enable SPI.
The VM205 uses SPI to communicate with the Raspberry Pi. After enabling SPI, you will be asked to reboot.
If you did not fi nd an option to enable SPI under Advanced options, then you have an older version of NOOBS (< 1.4.0).

RUNNING THE VM205 APPLICATION
Running the VM205 application
Once the installation and confi guration is complete and you have booted into the graphical user interface of Raspbian,
you will need to download and install the VM205 software.
Go to the Velleman website and download the VM205 software package.
Unzip this package to your desktop. You should now have a fi le called VM205, this is the graphical application.
Before running the application, you will need to modify
its permissions to make it runnable.
Right-click this fi le and select Properties. Make sure the fi le
is readable and executable by Anyone, and click OK.
You are now ready to run the software.
Double-click the VM205 fi le and select Execute.
The VM205 application should now open on your desktop.
Click Run to start gathering oscilloscope data.

DE SHIELD MONTEREN
Controleer of de VM205-shield aangesloten is, voordat u de Rasberry Pi inschakelt. Wanneer u de shield aansluit terwijl de
Raspberry Pi ingeschakeld is, dan wordt de printplaat gereset, en kan dit een ongewenste reboot veroorzaken.

RASPBIAN INSTALLEREN
Gebruik een lege, geformatteerde SD-kaart, om de Raspbian te installeren met NOOBS. Sommige winkels verkopen reeds
voorgeprogrammeerde SD-kaarten.
Raadpleeg de website van Raspberry Pi voor meer informatie over NOOBS en de installatie. Volg deze instructies zorgvuldig
op. Download de laatste versie van NOOBS via
http://www.raspberrypi.org/help/noobs-setup/
BELANGRIJK: Na de installatie, start u voor de eerste keer op in het confi guratiemenu van Raspbian.
Selecteer Advanced Options, en activeer SPI. De VM205 communiceert via SPI met de Raspberry Pi.
Na het activeren van SPI, wordt u gevraagd om opnieuw op te starten.
Kunt u de optie SPI niet vinden onder 'Advanced Options', dan gebruikt u een oudere versie van NOOBS (< 1.4.0).

DE VM205-APPLICATIE GEBRUIKEN
De VM205-applicatie gebruiken
Wanneer de installatie en confi guratie voltooid zijn, en hebt opgestart in de grafi sche gebruikersinterface van Raspbian,
download en installeer de VM205-software.
Surf naar onze website www.velleman.eu en download het VM205-softwarepakket. Pak het pakket uit op uw bureaublad.
Het bestand VM205 verschijnt, dit is de grafi sche applicatie.
U moet de rechten wijzigen, om de applicatie uitvoerbaar
te maken.
Klik met de rechtermuisknop op dit bestand en selecteer
Properties. Controleer of het bestand leesbaar en
uitvoerbaar is door Anyone (Iedereen), en klik op OK.
De software is nu gebruiksklaar. Dubbelklik op het bestand
VM205 en selecteer Execute. Op uw bureaublad verschijnt
de applicatie VM205. Klik op Run om oscilloscoopgegevens
te verzamelen.
