+Name:
+=====
+ hello_world_uart
+
+
+Description:
+============
+ A simple "Hello World" example using the UART peripheral.
+
+
+Purpose:
+========
+This example prints a "Hello World" message with some device info
+over UART at 115200 baud. To see the output of this program, run AMFlash,
+and configure the console for UART. The example sleeps after it is done
+printing.

+# call it via python3
+# Examples:
+# (via python) 										ARTEMIS_BIN2BOARD=python "path_to_tool/ambiq_bin2board.py"
+# (via executable [windows]) 						ARTEMIS_BIN2BOARD="path_to_tool/ambiq_bin2board_installed.exe"
+# (via executable [*nix]) 							ARTEMIS_BIN2BOARD=./path_to_tool/ambiq_bin2board_installed
+# (via executable on in the default search path) 	ARTEMIS_BIN2BOARD=ambiq_bin2board_installed
