Summary:
Get the versions of FT4222H and LibFT4222.
Parameters:
ftHandle
Handle of the device.
pVersion
Pointer to a variable of type FT4222_Version where the value will be stored. Type
FT4222_Version is defined as follows:
struct FT4222_Version
{
DWORD chipVersion; // The version of FT4222H chip
DWORD dllVersion; // The version of LibFT4222
};
Revision A chips report chipVersion as 0x42220100.
Revision B chips report chipVersion as 0x42220200.
Revision C chips report chipVersion as 0x42220300.
Revision D chips report chipVersion as 0x42220400.
Revision B chips require version 1.2 or later of LibFT4222, indicated by dllVersion
being greater than 0x01020000;
Revision C chips require version 1.3 or later of LibFT4222, indicated by dllVersion
being greater than 0x01030000;
Revision D chips require version 1.4 or later of LibFT4222, indicated by dllVersion
being greater than 0x01040000.

Error code:
FT4222_DEVICE_NOT_SUPPORTED: This device is not a FT4222 chip.
FT4222_INVALID_POINTER: Parameter pVersion is NULL.
Example:
FT_HANDLE ftHandle = NULL;
FT_STATUS ftStatus;
FT4222_STATUS ft4222Status;
FT4222_Version ver;
ftStatus = FT_Open(0, &ftHandle);
if (FT_OK != ftStatus)
{
// open failed
return;
}
ft4222Status = FT4222_GetVersion(ftHandle, &ver);
if (FT4222_OK != ft4222Status)
{
// get version failed
return;
}
printf("%x %x\n",ver.chipVersion,ver.dllVersion);
FT_Close(ftHandle);
