FTDI sample for Windows Universal (UWP)

A sample application showcasing the FTDI D2XX driver use in Windows Universal projects (UWP). This sample is tested on the Raspberry PI 2 with Windows IOT installed and a FTDI FT232R usb-to-serial adapter.

This project uses the D2XX Windows RT driver from FTDI, see http://www.ftdichip.com/Drivers/D2XX.htm for the licensing and liability terms.

Installing the FTDI D2XX drivers on the Raspberry PI

1. go to \\[device-name]\c$\windows\system32, login with username: [device-name]\administrator and the administrator password
2. copy [ftdi.d2xx.winrt.cat](lib/D2xx WinRT 1.0.2/driver/ftdi.d2xx.winrt.cat) and [FTDI.D2xx.WinRT.inf](lib/D2xx WinRT 1.0.2/driver/FTDI.D2xx.WinRT.inf) from [lib\D2xx WinRT 1.0.2\driver](lib/D2xx WinRT 1.0.2/driver) to the folder above
3. start a remote powershell (as administrator) session to the Raspberry PI:

• start the remote service: net start WinRM
• add the Raspberry PI to the TrustedHosts if you haven't already: set-Item WSMan:\localhost\Client\TrustedHosts -Value [device-name]
• start the session with: enter-pssession -computername [device-name] -credential [device-name]\administrator this can take up to 30 seconds or more, so be patient

5. type cd c:\windows\system32 to go to the folder where the drivers are located
6. install the FTDI D2XX driver using the following command: devcon.exe dp_add FTDI.D2xx.WinRT.inf
7. reboot the device: shutdown /r /t 0
8. when rebooted reconnect again using last part of step 3
9. test the driver is working with: devcon status "USB\VID_0403&PID_6001", it should say something along the lines of:

USB\VID_0403&PID_6001\AH02A2KS
   Name: FT232R USB UART
   Driver is running.
1 matching device(s) found.

Note: the VID and PID need to match the model you are using, if you see 0 matching device(s) found. your FTDI device might use a different VID/PID . For an overview of the default VIDs/PIDS per model see the DeviceCapability section in: Package.appxmanifest or look up the Hardware Id in the device manager on Windows.

Limitations

• if you pull the usb adapter from the Raspberry PI the app will crash
• Toggling ASCII / hex output mode doesn't immediately switch but only after the next change to the read buffer
• there is no cancellation support in the read task, so if the device errors the device will most likely lock up

Setting up a new Windows Universal project using the D2XX

Note: you don't need to execute these instructions if you want to try the sample, this is just for a new project.

1. download the ARM Windows RT drivers http://www.ftdichip.com/Drivers/D2XX.htm (or look in the lib folder of this repository)
2. copy FTDI.D2xx.WinRT.USB.winmd, FTDI.D2xx.WinRT.winmd, FTDI.D2xx.WinRT.XML to your lib folder
3. in your new project add references to the files above
4. open the Package.appxmanifest file and make sure the Capabilities node has the following sub node:

<DeviceCapability Name="usb">
  <!--FT232AM, FT232BM, FT232R and FT245R Devices-->
  <Device Id="vidpid:0403 6001">
    <Function Type="name:vendorSpecific" />
  </Device>
  <!--FT2232D and FT2232H Devices-->
  <Device Id="vidpid:0403 6010">
    <Function Type="name:vendorSpecific" />
  </Device>
  <!--FT4232H Device-->
  <Device Id="vidpid:0403 6011">
    <Function Type="name:vendorSpecific" />
  </Device>
  <!--FT232H Device-->
  <Device Id="vidpid:0403 6014">
    <Function Type="name:vendorSpecific" />
  </Device>
  <!--FT-X-Series Devices-->
  <Device Id="vidpid:0403 6015">
    <Function Type="name:vendorSpecific" />
  </Device>
  <!--My Custom Device-->
  <!--<Device Id="vidpid:1234 4321">
      <Function Type="name:vendorSpecific" />
    </Device>-->
</DeviceCapability>
