Silly question: output hex value from DE1 to scope

Hello there,

Ok. I have a silly question about how to output hex value (16 bits) from Terasic DE1 to Tektronix O-scope through GPIO. I can see the counter in my Questasim, but now I want to see in hardware side.

Thanks,

Sean

    Your scope can only display a binary-bit per channel (though you could RC filter a PWM waveform to get an analog level).

    I'd recommend implementing an instance of the SignalTap II logic analyzer inside your DE1 FPGA, and capturing waveforms from that.

    Cheers,
