-Welcome to Level 1
-------------------
-
-This is a VERY simple program for the STM32L432 Nucleo-32 board. It simply
-iterates turning on the status led (LD3) and the pin D6.
-
-There is NO clock setting or anything, everything is the default bootup.
-
-There is a single source file, main.c, which defines all the code needed.
-
-There is a linker script which sets up the binary format properly ready to
-be flashed.
-
-This code can be flashed with
-
-  $ make flash
-
-this requires the program `st-flash` which is a part of the stlink programmer,
-which can be found at https://github.com/texane/stlink.git.
