EasyDriver Stepper Motor Driver V44

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. On this version (v4.4) we fixed the silk error on the min/max adjustment.This is the newest version of EasyDriver V4 co-designed withBrian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.Features:A3967 microstepping driverMS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)Compatible with 4, 6, and 8 wire stepper motors of any voltageAdjustable current control from 150mA/phase to 750mA/phasePower supply range from 7V to 30V. The higher the voltage, the higher the torque at high speedsExample:  Problem: I have a stepper motor but do not have the pinouts for the motor. How can I determine how to wire my stepper motor without the pinouts?Approach 1 (using a multimeter)Each of the two phases should have the same resistance when measured with a multimeter. When measuring the resistance across one wire from each of the two phases, the resistance should be infinite because the circuit is open. Locate the two pairs of wires that represent the two phases; both pairs of wires will have similar internal resistance.Connect each phase to the amplifier and ignore the polarity (+ / -), for now. You have a 50 percent chance of guessing right.Send a command to move the motor. If the motor rotates in the wrong direction, then switch either phase A and A- or B and B- (effectively reversing directions).  Code:////////////////////////////////////////////////////////////////////©2011 bildr//Released under the MIT License - Please reuse change and share//Using the easy stepper with your arduino//use rotate and/or rotateDeg to controll stepper motor//speed is any number from .01 -> 1 with 1 being fastest - //Slower Speed == Stronger movement/////////////////////////////////////////////////////////////////#define DIR_PIN 2#define STEP_PIN 3void setup() { pinMode(DIR_PIN, OUTPUT); pinMode(STEP_PIN, OUTPUT); } void loop(){ //rotate a specific number of degrees rotateDeg(360, 1); delay(1000); rotateDeg(-360, .1); //reverse delay(1000); //rotate a specific number of microsteps (8 microsteps per step) //a 200 step stepper would take 1600 micro steps for one full revolution rotate(1600, .5); delay(1000); rotate(-1600, .25); //reverse delay(1000); }void rotate(int steps, float speed){ //rotate a specific number of microsteps (8 microsteps per step) - (negitive for reverse movement) //speed is any number from .01 -> 1 with 1 being fastest - Slower is stronger int dir = (steps > 0)?
