From 01dd7804b87d60b2deab16712eccb3b97351a9b7 Mon Sep 17 00:00:00 2001 From: Damien George Date: Wed, 6 Sep 2017 13:40:51 +1000 Subject: ports: Make new ports/ sub-directory and move all ports there. This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way. --- stmhal/usrsw.c | 147 --------------------------------------------------------- 1 file changed, 147 deletions(-) delete mode 100644 stmhal/usrsw.c (limited to 'stmhal/usrsw.c') diff --git a/stmhal/usrsw.c b/stmhal/usrsw.c deleted file mode 100644 index a7721ad77..000000000 --- a/stmhal/usrsw.c +++ /dev/null @@ -1,147 +0,0 @@ -/* - * This file is part of the MicroPython project, http://micropython.org/ - * - * The MIT License (MIT) - * - * Copyright (c) 2013, 2014 Damien P.
