Code:

//-----------------------------------------------------------------------------
// Converts a single BCD-character to an int8.
//-----------------------------------------------------------------------------
int8 Int2Bcd(int8 val)
{
return ((val / 10) << 4) + (val % 10);
}

//-----------------------------------------------------------------------------
// Converts a single BCD-character to an int8.
//-----------------------------------------------------------------------------
int8 Bcd2Int(int8 BCD)
{
return (10 * (BCD >> 4)) + (BCD & 0x0F);
}

For an int32 you'l l have to call these functions 4 times, for example

Code:

int8 bcd, i;
int32 LargeValue;

for (i=4; i!=0; i--)
{
bcd = int2bcd( make8(LargeValue, i-1) );
putc(bcd); // Send to LCD
)
