Bipolar Stepper Motor

This series of examples presents how to drive a bipolar stepper motor using an AVR microcontroller, including the power stage.

• AVR^® EB Curiosity Nano
• Multi-Phase Power Board (MPPB)
• AVR-EB Curiosity Nano Adaptor to MPPB
• Motor used in the application: 17HS8401S Stepper Motor, but not mandatory
• A Voltage Power Supply (6-50V and 1-3A current capability, depending on the chosen motor)

In these applications, the bipolar stepper motor will be driven in three modes:

• Full-Step
• Half-Step
• Microstep

These modes will be explained in more detail in the following four applications. The complexity of the application will gradually increase.

• Basic example showing the stepper motor in Full-Step and Half-Step modes
• Adding the microstepping feature for precision increase
• Adding ramps(acceleration and deceleration) for better dynamic response
• Adding a second motor to demonstrate the PORTMUX peripheral. This scenario uses two motors alternatively. The motors do not rotate at the same time
