Xadow - Motor Driver

Xadow - Motor Driver

Xadow Motor can be used to control DC Motors. Its heart is a low-saturation two-channel bidirectional motor drive chip LB1836M, controlled by ATmega168 which handles the I2C communication with Xadow Main Board. Xadow Motor features a changeable I2C address. And it needs a separate low power to drive motors.

Specification:

• Motor Driver: LB1836M
• Battery Voltage: 2.5V ~ 9V
• Output Current per channel(Max): 300mA
• Communication Mode: I2C
• I2C Address is changeable

Usage:

This library is written for manage Xadow, include :

• get battery voltage from xadow motor board
• control motor run
• power down mode

Function:

there are some useful function as folowing:

Initialization

in fact , it's just initialize I2C wire

void begin()

Get Voltage of battery

this function will return voltage of battery

float getBatVol();

Set motor state

yep, this's the most useful function that can control the both motor

void setMotorRun(unsigned char sMotorA, unsigned char sMotorB);

there are 4 state you can use:

MSTOP       0                   // stop
MFOR        1                   // go forward
MREV        2                   // go reverse..
MHOLD       3                   // keep

APPLICATION

off curse you can find it in examples, there I'll show you how to use this library

#include <Wire.h>
#include "XadowMotor.h"

void setup()
{
    Serial.begin(38400);
    xadowMotor.begin();
}

void loop()
{

    Serial.print("bat vol :");
    Serial.println(xadowMotor.getBatVol());
    
    xadowMotor.setMotorRun(MFOR, MFOR);

    delay(2000);

    xadowMotor.setMotorRun(MSTOP, MSTOP);

    delay(500);

    xadowMotor.setMotorRun(MREV, MREV);

    delay(2000);

    xadowMotor.setPwrDown();
    delay(1000);
    xadowMotor.setWakeUp();

}
