Besides using the digital inputs with switches on the joystick ports, you can switch resistor sets on the pot inputs. If you use the four pushbuttons such that they are shorting out a string of resistors that are the series equivalent of a 100K pot then you can read the values just as you would a pot. We use a modified Radio Shack 2 pole 6 throw rotary switch to make a nice 11 position switch for program sub calls. The 11 positions have 10 9k (90K series resistance) resistors between them with a final 9K in series with the switch. At position 1 the resistance is 99k at postion 11 the resistance is 9K.
