Hi Pete! Please help to sort out this issue. This is my sample code in C# reading values from 0570 and 0574 offsets:
int altInt = 0;
int altFract = 0;
public double GetAltitude (ref Fsuipc fsui)
{
int token = new int();
bool result = new bool();
int dwResult = -1;
result = fsui.FSUIPC_Read(0x0574, 4, ref token, ref dwResult);
result = fsui.FSUIPC_Process(ref dwResult);
result = fsui.FSUIPC_Get(ref token, ref dwResult);
altInt = dwResult;
result = fsui.FSUIPC_Read(0x0570, 4, ref token, ref dwResult);
result = fsui.FSUIPC_Process(ref dwResult);
result = fsui.FSUIPC_Get(ref token, ref dwResult);
altFract = dwResult;
return CalculateNumber(altInt, altFract);
}
public static double CalculateNumber(int integerPart, int fractionPart)
{
return integerPart + fractionPart / (Math.Pow(10d, Math.Floor(Math.Log10(fractionPart) + 1)));
}
This code works fine except that cases when the fractial part is going negative and i receive such an output like this (where the "??????" stands for NaN):
