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
- 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);

{
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

GetTemperature
switch (dwOffset)

case VT1211_TEMPERATURE_SYSTEM:
return VT1211_TempTable[VT1211_ReadDate(VT1211_TEMPERATURE_SYSTEM)];
case VT1211_TEMPERATURE_CPU:

}
GetVoltage

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 );
