Abstract: A programming environment and a simple programming language that runs on Ethernet block-input/output (block-IO) devices and hosting servers. In some embodiments, the ARGEE™ system includes a web-based programming environment that compiles a GUI program into a bytecode program of a virtual machine; and the virtual machine that runs in the device firmware and executes the bytecode program representing the GUI program created by a user. There are many programming languages that provide a web-based programming environment. Some such languages apply to embedded devices. However, the ARGEE™ system, considered as a whole, is unique in that the programming environment is not hosted on the same embedded device it controls. The system reduces the FLASH-memory requirements of the device by hosting the environment on an external server. The system also facilitates a faster update cycle of the environment software, making it easier to distribute changes to customers when environment changes.

Abstract: A real time operating system (RTOS) for embedded controllers having limited memory includes a continuations library, a wide range of macros that hide continuation point management, nested blocking functions, and a communications stack. The RTOS executes at least a first and second task and uses a plurality of task priorities. The tasks share only a single stack. The task scheduler switches control to the highest-priority task. The continuations library provides macros to automatically manage the continuation points. The yield function sets a first continuation point in the first task and yields control to the task scheduler, whereupon the task scheduler switches to the second task and wherein at a later time the task scheduler switches control back to the first task at the first continuation point. The nested blocking function invokes other blocking functions from within its body and yields control to the task scheduler.
