hi all .
i have a pic microcontroller and i configured the port-d as input . port-d is 8-
bit, so in this case i have 8-inputs with values from 1 to 255 ,and if i connect
bit0 and bit1 to vcc i get this decimal value "3" and if i connect 4*4 keypad
so i have 16-inputs with corresponding value ,but in this case i cant press 2
buttons or 3 at the same time , now how can i get 16 inputs from 8-inputs
and can press or enter 2 inputs in the same time and get 2 values for it ?
is that possible ? am thinking for 2 days and i cant get it .
regards .
