Abstract

System and method for invoking code-generation functionality in a graphical programming language. User input is received to a graphical program node, e.g., a configured name control for a task or channel, where the graphical program node includes a task specification that specifies hardware and/or software for performing a task. The task specification may include channel configuration information for configuring a physical analog or digital channel of a device, and timing/triggering information. A code-generation function is invoked in response to the user input, and performed, thereby generating at least a portion of a graphical program in accordance with the task specification, where the graphical program implements the task. Based on the task specification, the function may generate example code that performs the task, configuration code executable to programmatically generate the task specification, and/or conversion code that converts the node from a first to a second type, each including the task specification.
