Address with the DS2438 battery monitor

[global]

Hello,
I'm using the DS2438 for monitoring a 10V NiMh battery, i need to read the voltage register and the current register.
So in the datasheet, the current register is in the page 0 byte 3 and 4. So i don't know how to wrote the address in my program the page is the first byte and the byte the second;

0x03 for page 0 byte 3
0x12 for page 1 byte 2

This is my code to read the voltage register :

void ReadVoltage (void)
{
if(!Reset())
{
WriteByte(SkipNetAdress); // SkipNetAdress Command
WriteByte(Read); // Read Registers Command
WriteByte(0x03); // Voltage Register Address
Voltage=ReadByte();
Voltage= Voltage<<8;
Voltage = Voltage+ReadByte();
Tension=((float)Voltage)*1/100; //10mV volt/bit, la pr飩sion n'est


}
}

I think you are confusing a nibble and a byte.

it doesn't working, i already use this code for the DS2770, i think i can use the same code, i just need to modify the adress. I don't know why it's not working.

Its now working, this is the code that we need to use, first read all the register, and to recover the data, we need to read the scratchpad:



if(!Reset())
{
WriteByte(0xCC); //skip ROM
WriteByte(0x44); //read temperature slot
}

if(!Reset())
{
WriteByte(0xCC); //skip ROM
WriteByte(0xB4); //read voltage slot
}

if(!Reset())
{
WriteByte(0xCC); //skip ROM
WriteByte(0xB8); //call memory page 00
WriteByte(0x00);

}

if(!Reset())
{
WriteByte(0xCC); //skip ROM
WriteByte(0xBE); //read page 00
WriteByte(0x00);
}

if(!Reset())
{
WriteByte(0xCC); //skip ROM
WriteByte(0xBE); //read scratchpad
WriteByte(0x00);
}

//read 9 bytes of data
Variable1=ReadByte();
Variable2=ReadByte();
Variable3=ReadByte();
Variable4=ReadByte();
Variable5=ReadByte();
Variable6=ReadByte();
Variable7=ReadByte();
Variable8=ReadByte();
Variable9=ReadByte();
