FEATURES OF THE DIGITAL FILTERS IMPLEMENTATION ON STM32 MICROCONTROLLERS

Abstract

The purpose of this work is to study the efficiency of compilation of digital filters software implementation for STM32 microcontrollers. The research included: the stage of filter synthesis according to its amplitude-frequency characteristic and order, analysis of the signal at the filter output for various types of the program code optimization. As a result of the research, practical recommendations were given for choosing a compiler and the level of optimization in devices containing digital filters.
