-i2c master mode tests.
-
-While many of the disco boards have some form of i2c device onboard,
-which would, on the face of it, make testing easy, it's a different
-device on each board, and there are boards without it.
-
-Instead, use a known I2C peripheral on all boards, and require/expect
-a known fixed i2c slave device.  (Eventually, this will be a soft
-controllable i2c slave in the auto test setup ;)
-
-the "trigger" pin is bounced when each iteration of the test code starts,
-allowing synchronization with a sigrok script that helps assure that
-results are as expected.
-
-Debug is via SWO wherever possible, uart (tx only) on less capable cores
-
-Pinouts: (External PullUps REQUIRED!)

-board		SCLK	SDA	i2cperiph	trigger	uart
