+====================================================
+EM32-32G880F128-H Examples miniblink-efm32lib README
+====================================================
+
+This is a port of the miniblink example to the efm32lib library.
+
+It's intended for the EM32-32G880F128-H eval board. It should blink LED1 on the
+board, just as the original miniblink example does.
