Hi everyone, I\'m trying to implement the following code on the NEXYS A7 board and it seems the I2C communication isn\'t working properly.

https://github.com/bdeloeste/Nexys-4-Temperature-Sensor--ADT-7420/blob/master/VGA%20Module/vga_temp_sensor.srcs/sources_1/new/I2C_temp.v

this my constraint file ===================================>

Was there a question in there somewhere?

So it is always stuck at FF value in the 7 segments, not showing any change in the temperature.

I assume that is not your intent? What do you want us to do?

The owner of the code clams to implement on the NEXYS A4 board. So I don\'t have a spare board to test if it has something to do with my NEXYS A7 board or a bug in the code.
Any help will be appreciated.
