 | `arduino.commandPath` | Path to an executable (or script) relative to `arduino.path`. The default value is `arduino_debug.exe` for windows,`Contents/MacOS/Arduino` for Mac and `arduino` for Linux, You also can use a custom launch script to run Arduino by modifying this setting. (Requires a restart after change) Example: `run-arduino.bat` for Windows, `Contents/MacOS/run-arduino.sh` for Mac and `bin/run-arduino.sh` for Linux. |
 | `arduino.additionalUrls` | Additional Boards Manager URLs for 3rd party packages. You can have multiple URLs in one string with a comma(`,`) as separator, or have a string array. The default value is empty. |
 | `arduino.logLevel` | CLI output log level. Could be info or verbose. The default value is `"info"`. |
-| `arduino.allowPDEFiletype` | Allow the VSCode Arduino extension to open .pde files from pre-1.0.0 versions of Ardiuno. Note that this will break Processing code. Default value is `false`. |
+| `arduino.allowPDEFiletype` | Allow the VSCode Arduino extension to open .pde files from pre-1.0.0 versions of Arduino. Note that this will break Processing code. Default value is `false`. |
 | `arduino.enableUSBDetection` | Enable/disable USB detection from the VSCode Arduino extension. The default value is `true`. When your device is plugged in to your computer, it will pop up a message "`Detected board ****, Would you like to switch to this board type`". After clicking the `Yes` button, it will automatically detect which serial port (COM) is connected a USB device. If your device does not support this feature, please provide us with the PID/VID of your device; the code format is defined in `misc/usbmapping.json`.To learn more about how to list the vid/pid, use the following tools: https://github.com/EmergingTechnologyAdvisors/node-serialport `npm install -g serialport` `serialport-list -f jsonline`|
 | `arduino.disableTestingOpen` | Enable/disable automatic sending of a test message to the serial port for checking the open status. The default value is `false` (a test message will be sent). |
 | `arduino.skipHeaderProvider` | Enable/disable the extension providing completion items for headers. This functionality is included in newer versions of the C++ extension. The default value is `false`.|
