Abstract. This work has been devoted to implementation of the software aimed at bi-cycle information models for LED bar graph displays. The principles of constructing software for built-in systems that reduce consumption of microcontroller resources for data output have been shown. A generalized approach to implementation of software support for LED scale in built-in systems based on microcontrollers has been formulated. The detailed practical algorithm concerning bi-cycle excitation of the multi-element LED bar graph display has been offered.

Keywords:LED, bar graph display, bi-cycle excitation, information model, algorithm, microcontroller, built-in system.
