The Arduino uses the handshake protocol to send characters out. It sends all the ASCII characters from 'A' to 'Z', and starts over. It sends an active-low Strobe signal and listens to an active-low Ack signal. The Arduino waits 1/2 second between each character. Whenever it sends 'A' it activates its yellow on-board LED. The LED is turned off when a 'B' (or any character other than 'A' is sent). This LED turns ON every 13 seconds approximately, and stays ON for approximately 1/2 second (26 characters * 0.5 sec = 13 sec). | The Arduino uses the handshake protocol to send characters out.

| + | * Simulate your solution circuit for Problem 1 with the Xilinx ISE. | ||
| + | * You only need to simulate the circuitry you will have built on the breadboard. No need to simulate a 6811! | ||
| + | * Include a screen capture of your schematics, and a screen capture of the Isim window. Either the waveform or the output in the console is sufficient. | ||
