The Sample code source you can download from

Source file: LCMctl_v2.2L_Src.tar.gz 

About source code.

1.We suggest using Code::Blocks as an IDE in Linux.

2.Or you can just use "make" to compile the source code in the vt1211hw/ folder or vt1211hw/src/ folder.
  And you can excute "vt1211hw" file in the LCMctlv22LSrc/src/ folder
 
 $cd vt1211hw/src/
 $make
 $./vt1211hw

Binary file: LCMctl_v2.2L_Bin.tar.gz

How to use the DEMO application

  1. Press the "Read Value" button , and then you can find the values in the below text boxes.

Sample code Introduction

Open VT1211

outb(0x87,VT1211A_CONFIGURATIN_INDEX_REGISTER);
outb(0x87,VT1211A_CONFIGURATIN_INDEX_REGISTER);

if ((VT1211_Read(VT1211A_CHIPSET_DEVICE_ID) == VT1211A_CHIPSET_DEFAULT_DEVICEID) )
{
    VT1211_Write(0x07,VT1211_HARDWAREMONTIOR_LDN);
    m_HardwareMonitor_IOBase = ( VT1211_Read (VT1211A_HARDWAREMONTIOR_IOBASE) << 8 ) | VT1211_Read (VT1211A_HARDWAREMONTIOR_IOBASE+1);
    return TRUE;		
}
else
    return FALSE;
return FALSE;
}

Read Data

DWORD dwPortVal;
dwPortVal = inb((WORD)(m_HardwareMonitor_IOBase + dwOffset));
return ( dwPortVal & 0x00FF);

GetTemperature

switch (dwOffset)
{
    case VT1211A_TEMPERATURE_SYSTEM:
        return VT1211A_TempTable[VT1211_ReadData(VT1211A_TEMPERATURE_SYSTEM)];
    case VT1211A_TEMPERATURE_CPU:
        return (VT1211_ReadData(VT1211A_TEMPERATURE_CPU)-73.869)/0.9528;
}

GetVoltage

float value ;
switch (dwOffset)
{
    case VT1211_VOLTAGE_CORE:
        value = (float)VT1211_ReadDate(VT1211_VOLTAGE_CORE) -3 ;
        return  (float)(value / 95.8);
    case VT1211_VOLTAGE_3V:
        value = (float)VT1211_ReadDate(VT1211_VOLTAGE_3V) -3 ;
        return  (float)(value / 95.8 /0.5952 );
    case VT1211_VOLTAGE_12V:
        value = (float)VT1211_ReadDate(VT1211_VOLTAGE_12V) -3 ;
        return  (float)(value / 95.8 / 0.1754 );
    case VT1211_VOLTAGE_VCC:
        value = (float)VT1211_ReadDate(VT1211_VOLTAGE_VCC) -3 ;
        return  (float)(value / 95.8 / 0.6296 );
}
