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, 

Dave

Thanks Dave, 

 

I will try SignalTap II.
