Control mediante joystick de tarjeta avr butterfly (con microcontrolador atmega169) mediante comunicación spi con tarjeta lpcxpresso controladora de motor bldc y presentación en display de mensajes de operación. (noviembre 2012)

Abstract

This project allows the development and implementation of a BLDC engine driver through a joystick built into the AVR Butterfly motherboard and through a messages display to control the engine, using the SPI(Serial Peripherical Interface) communication protocol, which is set in the LPCXpresso1769 card. This paper presents general theoretical concepts of SPI protocol functionality, its application in the LPCXpresso microcontroller, through which we will enable communication between devices; it is analized hardware tool, concepts, functioning and use of BLDC engines. It is explained the project design, code functioning, block diagrams, control engine algorithms and used of software tools: LPCXpresso and AVR STUDIO4, which allows C language programming. In the last part it is shown the schematic diagrams of the required steps and the elements to implement the project.
