Hi,

i dont think there is any promblem with the code. you should check if the FPGA pin assignment is done correctly... Since the chip is TTL competilbe, it must not have any promblem with 3.3 volt. Also you must power the ADC chip through power of DE1 board so that both the FPGA and ADC chip have same ground.
