A method, computer system, and graphical user interface for generating firmware code for a programmable integrated circuit are disclosed. Embodiments are directed to a configurable menu hierarchy which is displayed as part of a graphical user interface, and therefore may be configured on-screen by a user interacting with elements or regions of the graphical user interface. Once the hierarchy of the menu is configured, a data structure for implementing menu functionality associated with the displayed menu hierarchy may be automatically generated. Firmware may be generated based upon the data structure and stored within a programmable integrated circuit. The firmware may enable the programmable integrated circuit to implement the menu functionality external to the programmable integrated circuit using at least one component of the programmable integrated circuit. The menu functionality may operate in conjunction with at least one user interface device of the electronic device.
