/* * SendRawDemo.cpp - demonstrates sending IR codes with sendRaw * * This example shows how to send a RAW signal using the IRremote library. * The example signal is actually a 32 bit NEC signal. * Remote Control button: LGTV Power On/Off. * Hex Value: 0x20DF10EF, 32 bits * * If it is a supported protocol, it is more efficient to use the protocol send function * (here sendNEC) to send the signal. * * This file is part of Arduino-IRremote https://github.com/Arduino-IRremote/Arduino-IRremote. * ************************************************************************************ * MIT License * * Copyright (c) 2020-2022 Armin Joachimsmeyer * * Permission is hereby granted, free of charge, to any person obtaining a copy * of this software and associated documentation files (the "Software"), to deal * in the Software without restriction, including without limitation the rights * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell * copies of the Software, and to permit persons to whom the Software is furnished * to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included in all * copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, * INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A * PARTICULAR PURPOSE AND NONINFRINGEMENT.
