AVR469: MC301 Hardware User Guide (21 pages, revision A, updated 4/09)
The MC301 is the device board for ATtiny861 AVRŽ microcontroller which can be connected to the general-purpose power stage board MC300 for driving brushless DC, brushed DC and stepper motors. This board is also designed to be connected on any other driver board which could share the same interface. Power and all signals needed for a power stage board are available on the right side of the board. Jumpers allow demonstrating sensor or sensorless modes of motor control. Finally, interface like USB or Atmel DB101 Display module is also available.
AVR496: Brushless DC Motor Control using ATtiny861 (13 pages, revision A, updated 7/09)
This application note describes how to implement a brushless DC motor control in sensor mode using the ATtiny861 AVR microcontroller. The high performance AVRŽ core along with the Timer 1 of the ATtiny861 allows to design high speed brushless DC motor applications.
AVR498: Sensorless control of BLDC Motors using ATtiny261/461/861 (20 pages, revision A, updated 7/09)
This application note describes how to implement a brushless DC motor control in sensorless mode using the ATtiny861 AVRŽ microcontroller. In this document, we will give a short description of brushless DC motor theory of operations, we will detail how to control a brushless DC motor in sensorless mode and we will also give a short description of the ATAVRMC301 and ATAVRMC300 boards used in this application note.
