Abstract: A system and method for programmatically generating a graphical program in response to receiving input, e.g., user or process input. The input may specify functionality of the graphical program to be generated, and also indicate a target platform. In response to the input, a graphical program implementing the specified functionality may be programmatically generated for execution on the indicated target platform. Thus, different graphical programs, or different implementations of the graphical program, may be generated, depending on the input received. The graphical program (or implementation) may be at least partly optimized for execution on the indicated target platform. The graphical program may include a block diagram portion and a user interface portion, where the block diagram portion is specified for execution on the target platform, and the user interface portion is specified for execution on a computer system coupled to the target platform, e.g., for display of a user interface.

Abstract: A system and method for creating a graphical program utilizing one or more input/output (I/O) nodes. An I/O node may be displayed in a first graphical program, where the I/O node may include associated generation code for programmatically generating execution-time code associated with the I/O node in the first graphical program. First input may be received to select a first I/O source or target corresponding to the first I/O node, e.g., from various supported hardware resources, and the associated generation code may be executed to programmatically generate or modify the execution-time code, e.g., at compilation or prior to execution of the first graphical program, to provide I/O to or from the first I/O source or target.
