Efectos en la resolución de servomotores con interfaz PWM por la generación de señales en microcontroladores

Abstract

In this work, an ATmega328P microcontroller-based signal generation analysis is presented to develop a Phase Width Modulation Servomotor interface. The analysis was made of timers and some of its operation modes, configuration cases and effects over servomotor axis were observed as well. An operation theory and its mathematical relation can be seen to obtain a model that helps in the correct parameter management, in addition to right microcontroller programming to operate servomotors with hardware resources contained in the programmable device used to generate the signals. A simulation shows how the implemented code produces signals and which operating behavior has in the devices.
