Unable to Mount Virtual COM Port in Windows 10

If you are using Windows 10 (or any other operating system) and having problems getting a Virtual COM Port to be assigned to your system, follow these steps. We recently discovered after a Windows 10 Update, that Virtual COM Port drivers may not load any-longer by default for some devices. If you are unable to use Base Station or AnyI2C software because the COM port is not showing up, here’s an easy fix:

Jul 04, 2014  STM32 Virtual USB Com Port problem on Maverick OSX #23. Closed electricpocket opened this issue Jul 4, 2014 4 comments. However we cannot get it to work with a device which uses the STM32 chipset. It is listed as a modem device and when we connect to it we get no data. Anyone else come across this and know what the trick is to connect to it. Oct 16, 2017  Unable to Mount Virtual COM Port in Windows 10. If you are using Windows 10 (or any other operating system) and having problems getting a Virtual COM Port to be assigned to your system, follow these steps. We recently discovered after a Windows 10 Update, that Virtual COM Port drivers may not load any-longer by default for some devices.

Recent operating system updates, hardware (VCP Chip) revisions, and VCP drivers may prevent a Virtual COM Port from registering properly with your operating system. We have seen ALL THREE factors prevent proper operation. We STRONGLY ADVISE installation of the latest drivers for your particular operating system before going any further. NCD hardware uses FTDI drivers for most devices, you should download and install the latest FTDI drivers from here.

In most cases, this should resolve your virtual COM port registration problem and a new COM port should appear in “Device Manager”. If this does not mount the virtual COM port to your system, please follow the steps outlined below.

Step 1: Open Device Manager

Move your Mouse pointer to the lower left corner of the screen and type “Device Manager”. Click on the “Device Manager” as shown in Blue in the screenshot below.

Step 2: Examine the USB to Serial Converter Settings

With your USB device plugged in, Expand the “Universal Serial Bus controllers” list to reveal “USB Serial Converter”. Right click on “USB Serial Converter” and select “Properties”.

Step 3: Load the VCP Driver

After opening the Properties for the device, click on the “Advanced” tab and MAKE SURE the “Load VCP” option is checked. Once checked, click OK.

Step 4: Reconnect your USB Device

Disconnect the USB device and reconnect. The device should now be visible to your operating system.

If all goes well, your Virtual COM Port Driver will be loaded and ready to run. Now re-run Base Station Software (https://ncd.io/start) and your Virtual Serial Device should appear. This should also allow COM devices to list properly in AnyI2C software.

Alternative Solution

If the above steps did not work, and your computer has had unusually large number of COM ports assigned (more then 256), then it will not be possible to mount additional COM ports to your computer without cleaning up all unused ports. The process for cleaning up unused ports is as follows:

Automatic COM Port Removal Method

The following tool may be used to remove all hidden COM ports at once. This tools is published by FTDI, which is vetted and trusted by NCD:

From the command line, execute the following command:

Complete Documentation can be found here.

Manual COM Port Removal Method

From the command line, enter the following two commands:

This will open the device manager. Next you will need to review all COM ports that are hidden from view, but assigned to other devices that are not in use. To do this from device manager, click View>Hidden Devices.

Next, it will be necessary to delete all GRAY (not black) USB Serial Port devices that are not in use. This will take some time. To delete unused COM ports, right click on Grayed USB Serial Port Items and select “Uninstall Device”. Do not select the option for deleting the driver.

Now it will be possible to assign additional COM ports to your computer and devices will no-longer appear as unrecognized COM ports.

The WF200/WFM200 Wi-Fi Expansion Board is the best and fastest way to explore the capabilities of the WF200 Series of Wi-Fi Transceivers.The kit contains an expansion board that can be connected to a STM32 MCU starter-kit.The expansion board allows the STM32 MCU to connect to a WF200/WFM200 Wi-Fi module, which can connect to Wi-Fi networks, but also be an Access Point to which other devices can connect.

This document describes how to connect the WF200/WFM200 Wi-Fi EXP Board to a STM32 MCU and run the demonstration.

This demonstration runs the Wi-Fi Full MAC driver meant to communicate withthe WF(M)200 Silicon Labs Wi-Fi transceivers.

Naming convention

  • SoftAP: WF(M)200 configured in Wi-Fi Software-enabled Access Point mode
  • Station: WF(M)200 configured in Wi-Fi Station mode
  • AP: Any 'home network' or 'office network' Wi-Fi Access Point
  • Device: The PC or phone used to access the demo

Requirements

Hardware Prerequisites

The WF200 Wi-Fi Expansion Board contains a Wi-Fi module. To use the board, an MCU starter-kit is required, where the MCU will be the host that communicates and controls the Wi-Fi module.

  • One of the two Wi-Fi® expansion kits listed below:
WF200 Wi-Fi® Expansion Kit SLEXP8022AWFM200 Wi-Fi® Expansion Kit SLEXP8023A
  • An Arduino/NUCLEO interposer (Available through support ticket request,more information in the Additional Resourcessection) or some flying wires
  • A NUCLEO-F429ZI development board
  • A micro USB cable
  • A PC to load a binary file in the NUCLEO board or to compile the IAR/TrueSTUDIO projects. In addition, it can be used to test the example if it is equipped with a Wi-Fi interface.

Software Prerequisites

In addition to the previous hardware, a user needs software listed below:

  • The software example named F429ZI_freertos available on GitHub
  • Licensed IAR Embedded Workbench IDE for ARM installed or Atollic TrueSTUDIO for STM32 IDE
  • The correct ST-link driver installed on your machine
  • A Serial terminal to communicate with the NUCLEO-F429ZI board. For example, Tera Term or Putty

Set up your Kit

After you have the above resources, follow the steps described below (you can refer to the image below):

  1. Connect the Arduino/Nucleo interposer board to the NUCLEO-F429ZI board.

  2. Connect the WF200 expansion kit to the Arduino/Nucleo interposer board.

  3. Make sure the 'Power' switch on the WF200 expansion kit is in the [On Board LDO] position.

  4. Select [SPI] or [SDIO] on the bus switch depending on the bus you want to use.

  5. Connect the NUCLEO board to your PC using the USB cable. The board should appear as a mass storage device named 'NODE_F429ZI'.

Clone the GitHub Repository

  1. The example is hosted at GitHub. To download a copy of the example, go to the following link: https://github.com/SiliconLabs/wfx-fullMAC-tools. Press the Green button [Clone or Download] on the right side to download the repository as a zip file.

  2. After the download is complete, extract the zip file to a folder on your PC with a short name to avoid any issues with long path names (e.g. C:).

Flash the STM32 MCU

Use the Binary Files

The first option to run the demonstration is to use the precompiled binaries provided under wfx-fullMAC-tools/Examples/STM32/commissioning/F429ZI_freertos/Binaries/. Depending on the bus selected on the switch, choose the corresponding binary file:

  • F429ZI_freertos_spi.bin
  • F429ZI_freertos_sdio.bin

To use this method, drag-and-drop or copy the F429ZI_freertos_XXX.bin file to the 'NODE_F429ZI' mass storage.

After the STM32 is successfully flashed, jump to the Start the Example section.

Compile the Project

Alternatively, use your preferred IDE to compile and flash the project into the NUCLEO board.

  1. Open the project with either IAR or TrueSTUDIO IDEs.

  2. Select the bus configuration (SPI or SDIO). Make sure it matches the switch position on the WF200 EXP board.

  3. Build the project.

  4. Flash the project to the NUCLEO-F429ZI board.

After the STM32 is successfully flashed, jump to the Start the Example section.
