This function will read the dip switches on the STK1000 and put the status out on the leds. To get it to work, you must connect the input and output correctly on the STK1000. The input (switches) header marked J25 must be connected to the header labeled J2 (PORTB[15..8]). While the output (leds) header marked J15 must be connected to the header marked J1 (PORTB[7..]) <dl compact><dt><b>Parameters:</b></dt><dd>
