High analog input for DE1

Hi Doe's anybody knows how can analog signal that is higher than 3.3V be connected to the FPGA input? (without additional HW beside the DE1). Thanks Eyal

DE1 has no analog inputs except the audio codec's line and mic in. So you most likely need external ADC circuitry (or at least a comparator). What do you want to achieve?
