In this program, Arduino first set the speed of the 2 DC motors with the
MotorSpeedSetAB()
command,
and then set the DC motors work directions with
MotorDirectionSet()
command. Please refer to

How to driver a stepper using I2C motor driver V1.3
As the upgraded version of
, You can drive stepper via 2 methods for I2C motor driver
V1.3.
1. Control the stepper directly by Arduino
The I2C motor Driver can also be used to drive a 4-wire stepper. Connect your stepper to the output pins
of I2C motor driver, and then connect motor driver to your Arduino/Seeeduino with I2C bus. Program your
Arduino as below:
#include <Wire.h>
.......
.......
<
Driver functions
>
.......
.......
void
setup
()
{
Wire
.
begin
();
// join i2c bus (address optional for master)
delayMicroseconds
(
10000
);
//wait for motor driver to initialization
}
void
loop
()
{
while
(
1
)
{
MotorSpeedSetAB
(
100
,
100
);
//when driving a stepper, the speed should be set to 100;
delay

MotorDirectionSet

0b0001
);
delay
(

);
MotorDirectionSet
(
0b0011
);
delay
(
4
);
MotorDirectionSet
(
0b0010
);
delay
(
4
);
MotorDirectionSet
(
0b0110
);
delay
(
4
);
MotorDirectionSet
(
0b0100
);
delay
(

);
