Genuino/Arduino compatible board using the ATmega M1-familjen av mikro kontroller

Abstract: Arduino is a suite of software and hardware designed for the Atmel ATmega family of microcontrollers. In this project the Arduino suite has been adapted for the ATmega32M1 with the intent of utilising the built-in three phase motor controller and CAN bus interface, making it easier to quickly prototype electric vehicles or other new applications. There are a number of subtle differences between the ATmega32M1 and the ATmega328P used in the Arduino UNO. The hardware and software have therefore had to adapted and extended to fit the new microcontroller. Furthermore a Motor Shield was designed and produced for the three phase motor controller of the ATmega32M1. On the Motor Shield there are three high/lowside gate drivers and six power MOSFETs capable of working at up to 60V producing an estimated maximum 2kW of power. The overall design has proven successful with some minor bugs remaining. By relaxing the design requirements somewhat, much more powerful motors could be supported further extending the range of applications of the design.
