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/usbhost/Core/Src/usbh_ctlreq.c | 881 ---------------------------------- 1 file changed, 881 deletions(-) delete mode 100644 stmhal/usbhost/Core/Src/usbh_ctlreq.c (limited to 'stmhal/usbhost/Core/Src/usbh_ctlreq.c') diff --git a/stmhal/usbhost/Core/Src/usbh_ctlreq.c b/stmhal/usbhost/Core/Src/usbh_ctlreq.c deleted file mode 100644 index 58bc34d64..000000000 --- a/stmhal/usbhost/Core/Src/usbh_ctlreq.c +++ /dev/null @@ -1,881 +0,0 @@ -/** - ****************************************************************************** - * @file usbh_ctlreq.c - * @author MCD Application Team - * @version V3.0.0 - * @date 18-February-2014 - * @brief This file implements the control requests for device enumeration - ****************************************************************************** - * @attention - * - *
