+  - How could you improve the performance? How could the ARM/PRU programs be altered to send the data whenever a new signal was required (do not implement)?
+==== Submission and Evaluation ====
+As well as you demonstration you should submit a brief lab report. For the lab report submit your code, documenting the changes, and the answers to the questions above using the prism submit command.
