hi,
I have a problem with a SpartanII design. I am driving 5V logic devices with spartanII. These logic devices are L293D's for DC motor driving and AM26LS32 for receiving quadrature encoder signals. Spartan II's are 5V tolerable. I am working on a servo controller.
My problem is i am writing vhdl code. My first vhdl code does not involve all
the pins in the entity. When i write a new code and it includes additionally 1 pin and i write something to this pin my design fails. I could not understand the problem.
Has anybody got any idea to work around this problem?
