Week 9

Introduction
In this week's project we will be integrating a USB device with our FPGA. We will interface a keyboard and allow the FPGA to receive signals from the keyboard.
Task 1
In this task we will start by loading the example code onto the FPGA. The code alows the FPGA to display the scan code and value for a key pressed when a keyboard is attached to it.








Task 2
In this task we take this further by implementing a Serial communication from the FPGA to our computer. In doing this we are able to send keyboard signals to our computer via serial communication. This ultimately allows us to type a message to our computer using the FPGA. We can do this by implementing the previous serial transmission program created in Week 7. We can edit this code to allow us to transmit our keypress data in the form of ASCII values.



This code takes our received data and turns it into an ASCII code that is then passed on to our UART TX module.



Discussion
This project was an excellent introduction into using the FPGA with USB communication. This opens up a lot of posiblilities as USB is one of the most common modern data transmission protocols for consumer electronics
