Project 2: Digilent Pro MX7 and Delays

The purpose of this project is to investigate methods of creating software time delays to pace processor operations. The timing methods that control when a process is to be executed can be implemented by using polling techniques that sample a free running clock or by executing code that requires a fixed amount of time. This project also demonstrates the use of time delays for signal conditioning.
