Open Stepper Project

OpenStepper: "The OpenStepper Module (OSM) is comprised of a GSM_01 and the OpenStepper circuit board. OSM firmware is based on Mike Thompson's popular OpenServo project which Jay Ragsdale was kind enough to port to the ATtiny84. Jay also wrote the low-level drive algorithm that makes this code work with a stepper-motor. With kind thanks to Barry Carter, current OpenServo admin and major project contributer, the OpenStepper code is now branch of the OpenServo CVS tree and available for download. You may visit the OSP software page and follow the links or go directly to OSM brows page."
