Abstract
A computer-based virtual instrumentation system including a host computer and an embedded system or device, wherein graphical programs created using the computer system can be downloaded to the embedded system for execution in a real-time or more deterministic manner. The present invention thus provides a method for automatically generating an embedded application in response to a graphical program created by a user. This provides the user the ability to develop or define instrument functionality using graphical programming techniques, while enabling the resulting program to operate in an embedded real-time system. The invention includes a novel method for configuring the embedded system. During execution of a graphical program in the embedded system, the block diagram portion executes in the embedded system, and the host CPU executes front panel display code to display on the screen the graphical front panel of the graphical program. The embedded system and the host computer exchange data using a front panel protocol to enable this operation. The present invention also includes improved debugging support for graphical programs executing on the embedded system. The host graphical p…
