To implement USB at the Verilog level is complicated. The Basys 3 board
has a PIC24FJ128 microcontroller that provides USB HID host capability.
We will use this option to develop the HDL projects here. Specifically,
we will focus on interfacing a keyboard to Basys3 board since the
PIC24FJ128 chip available on the board converts the USB input to
standard PS/2 signals to communicate with a mouse or keyboard. Here,
the Basys3 board will be the receiver. The keyboard will be the
transmitter. Therefore, we will focus only on the USB-receiving module
next.
The demonstration:
2. Send the Scan Code to a seriial terminal
We can combine the UART tx module here to display the key values on the serial monitor.
Draw the system diagram helps the desgin of the RTL:
Here is the video demonstration.
--------------- Tasks: 1. Repeat the work in Section 1. (10 points) 2. Design the testbench and the scan code to ASCII converter to display key values on the serial monitor. (90 points)
