Setting up a Raspberry Pi to control a WF32 with LabVIEW

I recently wrote an指导where I used a Raspberry Pi to control a WF32 over WiFi. Today I will share an extensive guide on how to set this up for your own applications!

Step 1: Connecting WF32 to WiFi

1. Launch the LINX Firmware Wizard.

2. Choose the chipKIT WF32.
3. Go to Device Manager.
4. Click on “Ports(COM & LPT)” to find the WF32’s COM port.
5. 选择您的设备COM端口。
6. 配置网络设置:
   • SSID是您网络的名称。
   • 分配Chipkit WF32可用的IP地址。您需要以后再次指定此IP地址作为Linxinit VI的输入。
   • 选择要使用的端口；除非您有理由使用另一个；您应该选择44300。
   • You will need to specify this IP address again later as an input to the LINX Init VI.
   • Specify the Wifi security type and passphrase.
     • Note: It is recommended that you disable network security to start and then re-enable it after you confirm the LINX connection is working.
7. Click Launch Example.

Step 2: Raspberry Pi Setup

1. Download a Raspbian image这里。
   • Linx是使用Raspbian Jessie开发的。
2. 单击Raspbian Jessie图像下的下载ZIP按钮。
3. Extract (unzip) the Raspbian image.
4. Google win32diskimager and click on the top link or click这里。
5. 下载Win32磁盘成像器。
6. 从您的下载文件夹中打开它。
7. Complete the installation, but uncheck both the View and Launch boxes after completing the Setup Wizard.
8. Open File Explorer and go to This PC.
9. 选择程序文件（x86）。
10. 选择ImageWriter。
11. Then, select Win32DiskImager.
12. Click on the folder next to the image file dialog box, and then select your raspbian jessie disk image.
13. Insert the SD card into your computer and set the device dropdown so your SD card is selected, then click Write.
14. Connect ethernet to the Raspberry Pi and power on your Raspberry Pi. Launch LabVIEW, and open the Target Configuration Wizard from Tools»MakerHub» LINX»Target Configuration.
15. 输入Raspberry Pi的主机名或IP，以及带有根特权的用户名和密码，然后单击“连接”。（最终您需要将Raspberry Pi连接到WiFi，请单击这里if you need help).
    • 默认主机名是“ RaspberryPi”。
    • 默认用户名是“ pi”，默认密码为“覆盆子”。
16. Click the Install Software tab and click Install. Then review any warnings and complete the installation.

步骤3：Raspberry Pi - 部署启动可执行

1. Open up the LabVIEW project that you want to run and then select File-> New.
2. 在“项目”文件夹中选择“空项目”。
3. A pop-up will ask you if you want to add the open VI to the new project, select Add.
4. 右键单击“项目：无标题项目1”，然后选择“新”»“目标和设备”。
5. Select “Raspberry Pi 2 B” in the LINX folder and click OK.
6. Right click “Raspberry Pi 2 B” and select Properties.
7. 在“常规”类别下，输入Raspberry Pi的IP地址（这应该是您在上一步中设置的IP地址）。
8. 下一步是为Raspberry Pi 2打开销钉图，以供以后使用。从前面板中，选择“帮助»makerHub»linx»” Pinout - Raspberry pi B.”
9. Next, enter the correct values for the TCP settings, RPI settings, and the WF32 settings for the project you are going to use(mine is shown below).
10. To make sure these values don’t change, click Edit»”Make Current Values Default.”
11. 将您选择的项目拉到Raspberry Pi 2部分，然后右键单击“构建规格”（我的称为“ RaspberryPi-WF32_FAN_CONTROL”）。然后选择新的»实时应用程序。
12. Rename the build specification.
13. 单击对话框左侧的源文件类别。
14. Under Project, Files select the top level VI (“Raspberrypi-WF32_Fan_Control” for me) and click the right arrow to add it to Startup VIs. Click OK.
15. Right click the new build specification and choose Build.
16. 单击完成。
17. 右键单击新的构建规范，然后选择运行作为启动。
18. 单击是重新启动目标。现在，每当目标启动时，VI将运行。

我的下一篇文章将向您展示我使用这些步骤进行的Labview项目。感谢您的阅读，并随时发表评论。
