C++ (Cpp) scanCodeToChar Examples

Example #1

File: kernel.c Project: kshmir/Arqui-2011

/* Handler del teclado */
void int_09() {
	char scancode;
	char eoi = EOI;
	_read(KEYBOARD, &scancode, 1);

	// We check if the scancode is a char or a control key.
	int flag = scancode >= 0x02 && scancode <= 0x0d;
	flag = flag || (scancode >= 0x10 && scancode <= 0x1b);
	flag = flag || (scancode >= 0x1E && scancode <= 0x29);
	flag = flag || (scancode >= 0x2b && scancode <= 0x35);
	if (flag)
		pushC(scanCodeToChar(scancode)); //guarda un char en el stack
	else
		controlKey(scancode); // Envia el scancode al analizador de control keys.

	_write(PIC1, &eoi, 1);
}
