XADOW

Written by Loovee, distributed under LGPL, for more information, please visit http://www.seeedstudio.com

This library is written for manage Xadow, include :

• user led
• charge state read
• battery voltage read
• sleep mode operation

FUNCTION

you can use the folowing function, it's useful in some way.

Initialization

void init();

Get Voltage of battery

float getBatVol();

Get Charge State

unsigned char getChrgState(); 

it'll return the folowing value:

#define NOCHARGE            0
#define CHARGING            1
#define CHARGDONE           2

User Led

there'are two user led that you can use, a green one and a read one.

void greenLed(unsigned char state);             // green Led drive
void redLed(unsigned char state);               // red led drive

about the input value, you can use:

#define LEDON               1               	// led on
#define LEDOFF              2               	// led off
#define LEDCHG              3               	// change led state		

Power Manage

of curse, sometimes you want your xadow goto sleep to save some power, then you can use this function:

void pwrDown(unsigned long tSleep);             // power down, tSleep ms

it'll let your xadow goto sleep for sSleep ms, then it'll wake, you shourld use the folowing function to awake it:

void wakeUp();                                  // wake up

APPLICATION

there'are some application here, for more applicaton you can refer to examples

POWER DOWN MODE

#include <Wire.h>

#include "xadow.h"

void setup()
{

	Serial.begin(115200);
	// while(!Serial);
	Xadow.init();
		
	delay(2000);
	cout << "init over" << endl;
}

void loop()
{
	cout << "begin to sleep for 1s" << endl;
	Xadow.pwrDown(1000);                        // sleep for 1000ms
	Xadow.wakeUp();                             // wake up
	cout << "wake up" << endl;
	delay(500);                                 // delay 500 ms
}

READ VOLTAGE OF BATTERY

#include <Wire.h>

#include "xadow.h"

void setup()
{
	Serial.begin(115200);
		
	while(!Serial);
	Xadow.init();
		
	delay(1000);
	cout << "init over" << endl;
}

void loop()
{
	cout << "vol: " << Xadow.getBatVol() << endl;
	delay(500);
}

USER LED

#include <Wire.h>

#include "xadow.h"

void setup()
{
	Xadow.init();
}


void loop()
{
	Xadow.greenLed(LEDON);					// green led on
	Xadow.redLed(LEDOFF);                   // red led off
	delay(200);
	Xadow.redLed(LEDON);                	// red led on
	Xadow.greenLed(LEDOFF);              	// green led off
	delay(200);
}
