From 38746242eab47845c1b1b6cb264c3e3041977488 Mon Sep 17 00:00:00 2001 From: Thomas Tsou Date: Fri, 13 Aug 2010 12:59:32 -0700 Subject: usrp1: Add USB transport interfaces This patch adds generic interfaces for control and zero-copy transport of data between the host and a slave device. The interfaces are separate and generic to accommodate multiple implementations that may include cross platform libraries such as libusb or a platform specific implementation such as Linux usbfs. --- host/include/uhd/transport/CMakeLists.txt | 2 + host/include/uhd/transport/usb_control.hpp | 76 ++++++++++++++++++++++++++++ host/include/uhd/transport/usb_zero_copy.hpp | 64 +++++++++++++++++++++++ host/include/uhd/types/CMakeLists.txt | 1 + host/include/uhd/types/usb_descriptor.hpp | 49 ++++++++++++++++++ 5 files changed, 192 insertions(+) create mode 100644 host/include/uhd/transport/usb_control.hpp create mode 100644 host/include/uhd/transport/usb_zero_copy.hpp create mode 100644 host/include/uhd/types/usb_descriptor.hpp (limited to 'host') diff --git a/host/include/uhd/transport/CMakeLists.txt b/host/include/uhd/transport/CMakeLists.txt index 93e9a6485..dd1a20eed 100644 --- a/host/include/uhd/transport/CMakeLists.txt +++ b/host/include/uhd/transport/CMakeLists.txt @@ -25,6 +25,8 @@ INSTALL(FILES if_addrs.hpp udp_simple.hpp udp_zero_copy.hpp + usb_control.hpp + usb_zero_copy.hpp vrt_if_packet.hpp zero_copy.hpp DESTINATION ${INCLUDE_DIR}/uhd/transport diff --git a/host/include/uhd/transport/usb_control.hpp b/host/include/uhd/transport/usb_control.hpp new file mode 100644 index 000000000..6b5591a21 --- /dev/null +++ b/host/include/uhd/transport/usb_control.hpp @@ -0,0 +1,76 @@ +// +// Copyright 2010 Ettus Research LLC +// +// This program is free software: you can redistribute it and/or modify +// it under the terms of the GNU General Public License as published by +// the Free Software Foundation, either version 3 of the License, or +// (at your option) any later version. +// +// This program is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
