| - | Look over the top-level file. You will see that it uses your debouce circuit from a previous lab, which ensures that when you hit the send button, only a single character is sent. The seven segment controller displays the current value of the switches to help quickly determine the hexadecimal value and compare it to an ASCII table. | + | Look over the top-level file.

For each one, explain the following: What does this ERROR or CRITICAL WARNING refer to and do you understand why was it flagged? Is it OK or not for you to ignore it and assume the design will work in hardware (and if so, why)? Please explain. | ||

| - | Once the bitstream has been generated, download your bitstream to the FPGA. To test the transmitter, you will need to run a program called "PuTTY" that is installed on your computer.

To test the transmitter, you will need to run a program called "PuTTY". Follow the [[tutorials:putty_personal_machine|PuTTY tutorial]] to set it up if you are running on your own machine. If you are running on a lab machine it should already be installed. |
| - | If your PuTTY terminal is configured properly you should be able to send characters to the terminal by selecting the [[http://www.asciitable.com/|ASCII]] value of the character to send on the switches and pressing the center button. | + | After installing, specifically, follow the testing procedures outlined to ensure that PuTTY is working on your machine. That way, if your downloaded circuit design doesn't work you will know that PuTTY is not the reason. |

| + | The above are called "control characters" since they control the screen rather than draw characters. They are typically reached on normal keyboards using the "Control" key like a shift key (press concurrently with another key). Thus, when you hit Control-C to kill a program on a computer you are sending (or at least with older computers were sending) the ASCII character 8'h03. | ||

Test it against a variety of characters from the ASCII table at the end of your textbook - digits, punctuation, and both upper and lowercase letters. Show what happens when you send some of the special characters mentioned above - do you get interesting or meaningful stuff? How about for characters with values 8'h80 and above? |
