You will have to write the code to support the display.

If you just want to display the program number you don't need a micro controller. There are 7 segment display controller chips you could use. Have a look at this for some examples. http://www.electronics-tutorials.ws/com ... omb_6.html

You would just connect the inputs of the chip to the S0, S1 and S2 pins on the FV-1 and the display would show which ever program number was selected.

MC14495 or DM9368 chips can display 0 - 9 and A - F which gives 16 values in hex. The chips are obsolete but you can still buy them on ebay and other places.
