1. MountLV4E2014SP1-Win.iso


2. Navigate toLabVIEW2014folder3. Runsetup


1. NavigatetoLabVIEW2016folder*2. Runsetup


*Optional

1. Install VIPackage Manager2. OpenVIPackage Managerandsearch for«Linx»


2. Choose toinstall «Digilent Linx»on LabVIEW 20143. Install then forLabVIEW 2016*


*Optional

v Raspberry Pi2/3setup

Alternativ1:Usingarouter (recommended)1. Connectthe Raspberry Pi2/3toarouter

using anEthernetcable2. Powerupthe Raspberry Pi2/3using the

mini-usb cable

v Raspberry Pi2/3setup

Alternativ2:Directly toPC1. Follow the instructions on this page:

(http://www.instructables.com/id/Direct-Network-Connection-between-Windows-PC-and-R/)

v LabVIEWRun-Timeinstallasion onRaspberry Pi2/3

1. Create anew «BlankProject»inLabVIEW 2014(Not2015/2016)


2. Configurate Linx target(Tools->MakerHub ->Linx ->Linx TargetConfiguration…)


3. ConnecttoTarget(EnterIPaddress,username andpassword)


Note;Ifyou dontknow the IPaddressfollow these instructions:(https://www.raspberrypi.org/documentation/remote-access/ip-address.md)

4. Click «Install software»and«Install»


5. When completed,click «OK»(LabVIEWRun-Timeisnow installed on the Raspberry Pi2/3)


v Connecting toRaspberry Pi2/3

1. Add anew «TargetandDevices»(RightClick Project->New->TargetandDevices)


2. Select«Newtargetordevice»andLinx «Raspberry Pi»


Note:IfLINXfolderisnotavailable(notshowing),goto;«ProgramFiles(x86)\NationalInstruments\LabVIEW2014\vi.lib\MakerHub\LINX\Resources»andextract«LinxProvider2014.zip»into«ProgramFiles(x86)\NationalInstruments\LabVIEW2014»folder.

Overwritefilesifaskedfor

3. Rightclick «Raspberry Pi2B»andselect «Properties»


4. Insert the «IPaddress»(andchange «Name»if wanted)


5. Rightclick «Raspberry Pi»andthen «Connect»


6. There should now beagreenlight(indicator)showingon the rightsideof the «Raspberry Pi»icon


v Uploading «Blink»example toRaspberry Pi2/3

1. Click on «Help»and«Find Example»


2. Search for«Linx»andselect «Linx – Blink(Advanced).vi»


3. Inthe block diagram;Remove «Serialport»(redcross)andchange inputfrom«Serial»to«Local I/O»(blue arrow)


4. Inthe frontpanel;Change inputfrom«13»to«7»5. Rightclick andselect «Makecurrent value default»


5. Savethe .VIandname itBlink_test(File->Saveas->Rename ->«Blink_test»)


6. Draganddrop the .VIinto «Raspbery Pi3»7. Add new Real-TimeApplication

(Rightclick «Build specifications»->«New»->«Real-TimeApplications»)


8. Name the build specification «Blink»


9. Setthe .VIas«Startup Vi»(Sourcefiles->Select.VIandclick blue arrow )


10. Build the .VI(Rightclick on .VIunder«Build specifications»andclick «Build»)


11. Setthe built .VIasstartup(Rightclick on .VIunder«Build specifications»andclick «Runasstartup»)


12. Rebot the target(Raspberry Pi)(Click «Yes»when promoted toreboot the target)


v Running the «Blink»example

1. Remove the Ethernetcable2. Connect/build asshown below3. Powerupthe Raspberry Pi2/3(miniusb)4. Confirm that the LEDisblinking!

v «Temp_test»example using TMP36

v «Temp_test»example using TMP36

«Temp_test example»Ø Temp_test.viØ Convert_ADC_Voltage.viØ Gen_bytes.viØ V_to_degrees

1.Build the .viexample shown below:

v Uploading «Temp_test»example toRaspberry Pi2/3

1. Draganddrop the Temp_test.VI(andits subVI’s)into «Raspbery Pi3»2. Add new Real-TimeApplication3. Set«Temp_test»asstartup VIandthe subVI’s asAlways included4. Setthe built .VIasstartup andrebot the target(Raspberry Pi)
