Bays3 Programming Issue

[ulvarg]

Hi,

 

Ever since I programmed my Basys3 board via JTAG for the first time, I noticed that the 7-segment displays would stay slightly on despite not using them in my projects. Is this type of behavior to be expected? If not, does anyone know how to overcome this issue?

 

Thank you.

This behavior is normal — since the I/O pins connected to the seven-segment display are not used by your design, they are all being weakly pulled down by default.

 

You can fix this by changing the default state of unused pins to floating. Open the process properties for "Generate Programming File", and set "-g UnusedPin" (under the "Configuration" section) to "Float".

No problem, I removed the others.

Thank you for your answer, duskwuff. I talked to one of my professors at school, and he told me the same as you a couple of days after I made this post. I hope this answer may be of use to others as well.
