Display Configuration Generator is a standalone tool which uses HMI file to generate Nextion Display class in which you have references to:
  • Fonts
  • Images
  • Pages
  • Components

Using this class you can access Nextion Display components using strongly typed objects. Tool is included in the driver package and required .NET 4.0 to run.
Using visual studio build event's you can always have your class up-to-date.



You can run tool from command line every time you change you HMI file or you can use Visual Studio build events in project configuration to make VS updates you class file every time you build your project.
