Abstract. The article considers the principles of designing and implementing software for microcontrollers used in discreteanalog display devices. The main attention is paid to the development of a twocyclic information model, which allows minimizing energy consumption and increasing the reliability of data presentation in ergatic systems. An analytical representation of the dynamic information model, its technical implementation using a matrix connection of LEDs, and a generalized display control algorithm are proposed. The presented methods include optimizing the program code, reducing the load on the microprocessor, and ensuring the stability of the data visualization system. The generalized software approach is universal and adaptable to displays of any dimension, making it promising for use in automated control systems.
Keywords: LED, bar graph display, twocycle excitation, LED degradation, electromagnetic interference, information model, algorithm, microcontroller, software, embedded system.
