Nucleo F746ZG board from ST Micro. See
http://www.st.com/web/catalog/tools/FM116/CL1620/SC959/SS1532/LN1847/PF261636
The Nucleo F746ZG order part number is NUCLEO-F746ZG. It is clumped together
under the STM32 Nucleo-144 board family. This does provide uniformity in the
documentation from ST and should allow us to quickly change configurations

GPIO - there are 144 I/O lines on the STM32F746ZGT6 with various pins pined out
on the Nucleo F746ZG
See https://developer.mbed.org/platforms/ST-Nucleo-F746ZG/ for slick graphic
pinouts.
Keep in mind that:
1) The I/O is 3.3 Volt not 5 Volt like on the Arduino products.
2) The Nucleo-144 board family has 3 pages of Solder Bridges AKA Solder
Blobs (SB) that can alter the factory configuration. We will note SB
in effect but will assume the facitory defualt settings.
Our main concern is establishing a console and LED utilization for
debugging. Because so many pins can be multiplexed with so many functions,
the above mentioned graphic is super helpful in indentifying a serial port

OFF - means that the OS is still initializing. Initialization is very fast so
if you see this at all, it probably means that the system is hanging up
somewhere in the initialization phases.
GREEN - This means that the OS completed initialization.
BLUE - Whenever and interrupt or signal handler is entered, the BLUE LED is
illuminated and extinguished when the interrupt or signal handler exits.
RED - If a recovered assertion occurs, the RED LED will be illuminated
briefly while the assertion is handled. You will probably never see this.
Flashing RED - In the event of a fatal crash, all other LEDs will be
extinguished and RED LED will FLASH at a 2Hz rate.
