Technical Overview
This demo uses the single keyboard API call Keyboard_Key() to read the keyboard. It then displays the key using both
integer as well as ASCII format. The listing below is an excerpt of the main() program:
int main()
{
int key;
char sbuffer[64]; // printing buffer
// Always call ConfigureClock first
SYS_ConfigureClock(MAX_FCY_RATE);
// initialize SPI
SPI_Init();
// give Propeller driver time to boot
DELAY_MS( 2500 );
// clear screens
NTSC_ClearScreen();
VGA_ClearScreen();
// set NTSC color
NTSC_Color(0);
NTSC_Term_Print(" PS/2 Keyboard Demo");
NTSC_Term_Char( 0x0D );
NTSC_Term_Print(" Press keys on local keyboard.");
NTSC_Term_Char( 0x0D );
// set VGA color
VGA_Color(0);
VGA_Term_Char( 0x0D );
VGA_Term_Print(" Press keys on local keyboard.");
