Port manipulation PINx commands with Arduino Due ?

Hardware Arduino Due

Hi.

Like Baltasar, I'm struggling with this issue also.

The compiler likes that method to deal with ports, but now I'm stuck after. It has something to do with pins_arduino.h.

When compiler gets this lines:

P_RS = portOutputRegister(digitalPinToPort(RS));
B_RS = digitalPinToBitMask(RS);
P_WR = portOutputRegister(digitalPinToPort(WR));
B_WR = digitalPinToBitMask(WR);
P_CS = portOutputRegister(digitalPinToPort(CS));
B_CS = digitalPinToBitMask(CS);
P_RST = portOutputRegister(digitalPinToPort(RST));
B_RST = digitalPinToBitMask(RST);

It says:

D:\Docs\Arduino\arduino-1.5\libraries\UTFT\UTFT.cpp: In constructor 'UTFT::UTFT(byte, int, int, int, int, int)':
D:\Docs\Arduino\arduino-1.5\libraries\UTFT\UTFT.cpp:158: error: base operand of '->' has non-pointer type 'const PinDescription'

D:\Docs\Arduino\arduino-1.5\libraries\UTFT\UTFT.cpp:165: error: base operand of '->' has non-pointer type 'const PinDescription'

This is pointing to file variant.cpp, to this function:

/*

  • Pins descriptions
    */
    extern const PinDescription g_APinDescription[]=
    {
    // 0 .. 53 - Digital pins
    // ----------------------
    (...)

The operand '->' is not seen inside the function, I don't understand what the compiler want.

Can someone help?
