how to program this small display+keyboard system?
when you push the first button,the Digitron will display the number"1"
when you push the second button,the Digitron will display the number"2"
when you push the third button,the Digitron will display the number"3"
and the rest in the same way.
note: P3^0 andP2 are output
P0^0 is input
