- Stepper.cpp - - Stepper library for Wiring/Arduino - Version 0.4
-
- Original library (0.1) by Tom Igoe.
- Two-wire modifications (0.2) by Sebastian Gassner
- Combination version (0.3) by Tom Igoe and David Mellis
- Bug fix for four-wire (0.4) by Tom Igoe, bug fix from Noah Shibley
-
- Drives a unipolar or bipolar stepper motor using 2 wires or 4 wires
-
- When wiring multiple stepper motors to a microcontroller,
- you quickly run out of output pins, with each motor requiring 4 connections.
-
- By making use of the fact that at any time two of the four motor
- coils are the inverse of the other two, the number of
- control connections can be reduced from 4 to 2.
-
- A slightly modified circuit around a Darlington transistor array or an L293 H-bridge
- connects to only 2 microcontroler pins, inverts the signals received,
- and delivers the 4 (2 plus 2 inverted ones) output signals required
- for driving a stepper motor.
-
- The sequence of control signals for 4 control wires is as follows:
-
- Step C0 C1 C2 C3
- 1 1 0 1 0
- 2 0 1 1 0
- 3 0 1 0 1
- 4 1 0 0 1
-
- The sequence of controls signals for 2 control wires is as follows
- (columns C1 and C2 from above):
-
- Step C0 C1
- 1 0 1
- 2 1 1
- 3 1 0
- 4 0 0
-
- The circuits can be found at
