Just clone the latest repository and access this folder. To load it onto Chrome, open the options menu in your Chrome browser (3 vertical dots in my browser), find the "More Tools" menu, and click "Extensions". In the top right of the new menu that opens, enable Developer Mode by pressing the slider, then click "Load Unpacked" and select the ChromeExtension folder. Voila! You can pin this to your taskbar after you open it in Windows, so it's more like a standard piece of software on your computer.
This is the same software that's loaded on your device when you access its server page, but is now also standalone as a Chrome browser extension. Saves you some hassle, and enables the USB connection in tandem with the web features. The Serial library we created (mostly Diego's work from the Statechanger project) for the Chrome Extension is generalized, meaning we could hypothetically integrate any other devices in that use standard serial protocols to greatly expand our software (in due time, gotta make it fancy first), and later we'll be adding Bluetooth support as well, as Chrome browsers also have that capability without too much effort required to utilize it.
To use the USB connection, click "Get" in the top right of the page if you don't see the "Silicon Labs" device option (the HEG), then click "Set" to connect to it and allow you to control it with the interface. You can right click the page and click "Inspect" to see the data stream and check errors if you are getting any.
For the WiFi, you connect to your device's WiFi signal, then click "Connect" in the Data menu (with a custom definable Host IP if you have a custom IP (e.g. if the device is tied to your main network)). It should start after that. Be sure your device is up to date for this to work properly.
