This application is designed to be a template for a device that needs the WiFi configured before the main functionality is available. It provides the ability to configure the device to connect to an existing WiFi network. The hardware used is an ESP32 device with a TFT screen connected. This is similar to the Huzzah featherwing device. A schematic of the hardware is included below.
This git repo contains a submdule (lvgl). Therefore use the --recurse-submodules git command line option when cloning the repo.
Before compiling the code (running build.sh) you'll need to install the mos tool as detailed at https://mongoose-os.com/docs/mongoose-os/quickstart/setup.md.
If no station WiFi SSID is configured the user is guided through a wizard style interface to configure the GUI. This interface presents the following screens

When a WiFi SSID has been configured then the user is presented with a screen that contains a button to load the factory default configuration.
This is a starting point for you to implement the GUI for your application.
