Topic: Tft 3.2 Touch will just not work -.- (Read 2 times) previous topic - next topic

Martin1454

Hi there - im pretty new to arduino, and have played around with it for around 2 month - but today i recived my 3.2 tft touch screen ( TFT01-3.2 / ITDB02)
so i hooked it up to the shield i recived for it(so it works with an UNO instead of mega) - the only thing i else have done is installed library ITDB02_Graph16
and ITDB02_Touch - also i have maked sure that the code is set for the UNO with shield - but now when i tries to load an example code from the library it says " Invalid conversion from 'uint8_t*' to 'int'

so what do i do?

oh also i did remove a *
from the code the library ITDB02_Graph16.h        the * from the code #include "WProgram.h"

struct _current_font
{
   uint8_t* font;
   uint8_t x_size;
   uint8_t y_size;
   uint8_t offset;
   uint8_t numchars;
};

so what can it possible be i need to do?

You need to post your code.
