Functie declarata si neluata in seama...delphi

Am urmatoarea eroare:

Undeclared Identifier: FT_ReadEE


Linia este in MAIN.pas


PortStatus:=FT_ReadEE(ftHandle,Offset,EEPromData[Offset]);

In Main.pas la Uses am printre altele D2XXUnit

In D2XXUnit.pas am..

// EEPROM primitives - you need an NDA for EEPROM checksum
function FT_ReadEE(ftHandle:DWord; WordAddr:DWord; WordRead:Pointer):FT_Result; stdcall; External FT_DLL_Name name 'FT_ReadEE';


De ce primesc acel mesaj de eroare, din moment ce d2xxUnit e declarat, .dll este in folder (este si driverul instalat, dealtfel)?

Multumesc

Incearca

External FT_DLL_Name name 'FT_ReadEE.dll';

.dll este ftd2xx.dll.

In el se regasesc toate functiile referitoare la FTDI

Si e declarata:

FT_DLL_Name = 'FTD2XX.DLL';

Am reusit folosind o functie modificata.

USB_FT_ReadEE(Offset)

function USB_FT_ReadEE(WordAddr:Dword) : FT_Result;
begin
Result := FT_ReadEE(FT_Handle,WordAddr,@WordRead);
end;


Acum am alta belea: vreau sa scriu in FTDI dar imi scrie balarii.


S:='';
For Offset :=0 to $4F  do
begin
Read(OpenFile,EEPromArray[Offset]);
S:=S+IntToHex(EEPromArray[Offset],4)+' ';
If  ((Offset+1) mod $8) =0  then  S:= S +#13#10;

end;
ShowMessage(S);  //Imi arata continutul EEProm corect...deci se incarca in "array".


    Offset:=0;
  
  While Offset < $4F do
  
    If USB_FT_WriteEE(Offset,EEPromArray[Offset]) =FT_OK then
  //begin
  //ShowMessage ('FT_ ' + IntToStr( USB_FT_WriteEE(Offset,EEPromArray[Offset])));
  //ShowMessage (' Offset = '+ inttohex(Offset,4)+ '  Array = ' + inttohex(EEPromArray[Offset],4));
  //end;
    //end;
  Inc(Offset);

Ei, bine, dupa rularea ei imi umple eepromul de FF. Unde gresesc?

Functia cu rosu:


  function USB_FT_WriteEE(WordAddr:Dword; WordData:Word) : FT_Result;
begin
Result := FT_WriteEE(FT_Handle,WordAddr,WordData);
end;
