See for examples that work with Adafruit Motor Shield V2. The included examples AFMotor_* are for Adafruit Motor Shield V1 and do not work with Adafruit Motor Shield V2. ![]() This code uses speed calculations as described in "Generate stepper-motor speed profiles in real time" by David Austin or or with the exception that AccelStepper uses steps per second rather than radians per second (because we dont know the step angle of the motor) An initial step interval is calculated for the first step, based on the desired acceleration On subsequent steps, shorter step intervals are calculated based on the previous step until max speed is achieved. Install in the usual way: unzip the distribution zip file to the libraries sub-folder of your sketchbook. Tested on Teensy including Teensy 3.1 built using Arduino IDE 1.0.5 with teensyduino addon 1.18 and later.
