rGUI is a Windows Forms based interface that can be modified on the fly by adding,moving, resizing, and deleting dynamic controls including labels, buttons, text boxes, and graphs. It couples the power of HEW Target Server's direct memory interface with configurable controls to allow the developer to create a custom GUI in a matter of minutes; all without using a Windows programming environment! rGUI uses HEW Target Server to link each dynamic control with variables of the user's choice, achieving a high level of reusability, modifiability, and integration with HEW and any target MCU or MPU.
