09 | Wifi Setup

The chipKIT WF32 has an onboard Wifi radio that can be used to connect the WF32 to a Wifi network and control it remotely using LabVIEW. In this tutorial we'll configure the chipKIT WF32's Wifi settings and run a simple Blink example via Wifi.

N/A

• LabVIEW
• NI-VISA
• LINX

• Launch the LINX Firmware Wizard, choose the chipKIT WF32, it's COM port and the Wifi firmware.
  
  
• Configure the network settings:
  • SSID is the name of the network to connect to.
  • Assign the chipKIT WF32 an available IP Address. You will need to specify this IP address again later as an input to the LINX Init VI.
  • Select the Port to use. 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.
      
      
• Click Launch Example,
  
  
• Enter the IP Address and Port specified in the firmware wizard.
  
  
• Run the example and toggle the LED.
  
  
• Examine the block diagram and notice the only LabVIEW code change required for Wifi is to replace the Serial Port control with an TCP Configuration control.

• Modify the previous Physical Compute Kit examples to use Wifi rather than USB.
