- * Polling SPI loopback test.
- *
- * Bob is nowhere to be found, so Alice decides to talk to herself.
- *
- * Instructions: Connect SPI2 (Alice) to herself (i.e., MISO to MOSI).
- * Connect to Alice via SerialUSB.  Press any key to start.
- *
- * Alice will talk to herself for a little while.  The sketch will
- * report if Alice can't hear anything she says.  She'll then start
- * talking forever at various frequencies, bit orders, and modes.  Use
- * an oscilloscope to make sure she's not trying to lie about any of
- * those things.
- *
- * This file is released into the public domain.
- *
- * Author: Marti Bolivar <mbolivar@leaflabs.com>
