Ciao a tutti!!
Stavo leggendo le varie guide sulle PALib e mi sono fermato ad osservare questo pezzo di codice..

CODICE
// Includes
#include <PA9.h>       // Include for PA_Lib


char text[200]; // This will be our text...



// Function: main()
int main(int argc, char ** argv)
{
    PA_Init();    // Initializes PA_Lib
    PA_InitVBL(); // Initializes a standard VBL
    
    PA_InitText(1, 0);  // Initialise the text system
    
    PA_InitKeyboard(2); // Load the keyboard on background 2...
    
    PA_KeyboardIn(20, 95); // This scrolls the keyboard from the bottom, until it's at the right position
    // PA_KeyboardOut() can be used to scroll the Keyboard out
    // PA_ScrollKeyboardXY(x, y) can be used to set the keyboards position
    
    
    PA_OutputSimpleText(1, 7, 10, "Text : ");
    
    s32 nletter = 0; // Next letter to right. 0 since no letters are there yet
    char letter = 0; // New letter to write.
    
    // Infinite loop to keep the program running
    while (1)
    {
        // We'll check first for color changes, with A, B, and X
        if (Pad.Newpress.A) PA_SetKeyboardColor(0, 1); // Blue and Red
        if (Pad.Newpress.B) PA_SetKeyboardColor(1, 0); // Red and Blue
        if (Pad.Newpress.X) PA_SetKeyboardColor(2, 1); // Green and Red
        if (Pad.Newpress.Y) PA_SetKeyboardColor(0, 2); // Blue and Green
        
        letter = PA_CheckKeyboard();
        if (letter > 31) { // there is a new letter
            text[nletter] = letter;
            nletter++;
        }
        else if(letter == PA_TAB){// TAB Pressed...
            u8 i;
            for (i = 0; i < 4; i++){ // put 4 spaces...
                text[nletter] = ' ';
                nletter++;
            }
    
        }
        else if ((letter == PA_BACKSPACE)&&nletter) { // Backspace pressed
            nletter--;
            text[nletter] = ' '; // Erase the last letter
        }
        else if (letter == '\n'){ // Enter pressed
            text[nletter] = letter;
            nletter++;
        }
        
        PA_OutputSimpleText(1, 8, 11, text); // Write the text
        PA_WaitForVBL();
    }
    
    return 0;
} // End of main()

Precisamente questo frammento:

letter = PA_CheckKeyboard();
if (letter > 31) { // there is a new letter ?????? fischia.gif
text[nletter] = letter;
nletter++;
cosa vuol dire...? Nel senso la funzione PA_CheckKeyboard(); restituisce un char "lo passa" a letter e quel if(letter > 31)?? verifica che sia un vero carattere o che? PerchŔ >31 ho provato a ricompilarlo con valori a caso e il programma funziona lo stesso!!! 42.gif 42.gif aiudooooo!!!!

Grazie per l'aiuto!!! frantic4yc.gif frantic4yc.gif
