I cannot understand how to add a decimal point in DP1. The Code is working fine but there is no decimal point.


Hints: Keep the cc-codes in a separate array (codeArray[]) before sending them onto the display. Now add decimal point by ORing 0x80 with the relevant digit (content of codeArray[2]) and then transfer the codes of codeArray[] onto display.
