Hi, I'm newbie with FPGAs so I found the Mike Field's book and I bought both a Papilio One 500K and a LogicStart MegaWind board as suggested. The first time I plugged the LogicStart MegaWing on the Papilio One, it lighted up all the LEDs on it. Then I followed the book and after some issues I could finally generate a .bit file as described in "Your First Design" chapter. I tried to load it using the Papilio Loader but unexpectedly the program didn't work (the switches didn't light up any LED). But the real problem now is that the board began to smell burned. I tried to check it and I realized the ADC U1 IC was hotting!! Although I erased the FPGA with the Papilio Loader, the IC continues becoming very hot in a few seconds. I tried to check if there was any shortcircuit between the ADC port pins, but everything seems to be correct. I don't know what else can I check. My Papilio One jumper's settings are USB and 3.3V. Any help will be appreciated!
