1C8 hex. converted to BCD 456 No. BCD = Binary-Coded Decimal. That's a representation where each binary nibble (4 bits) represents one decimal digit, 0-9. Thus the Decimal number 456 would be represented in BCD as 010001010110 = 0x456 Decimal Digit: 4 5 6 Bits (Binary): 0100 0101 0110 strictly speaking, that's 8-4-2-1 weighted BCD - you could actually use any other 4-bit encoding (eg, Gray) of the ten decimal digits... convert BCD to ASCII
(4 + 48) = 52 for '4' (5 + 48) = 53 for '5' (6 + 48) = 54 for '6' You didn't explain where this "magic number" 48 comes from; Fortunately, Joseph has explained it: http://www.8052.com/forum/read.phtml?id=139235 you can write to LCD one by one i.e. 52 then 53 then 54 Assuming that your LCD scrolls characters from the right... |
