/* * IRremoteESP8266: IRsendGCDemo * demonstrates sending Global Cache-formatted IR codes with IRsend * Copyright 2009 Ken Shirriff * http://arcfn.com * * Version 0.2 June, 2017 * Added helpful comments * Better includes files. * Version 0.1 30 March, 2016 * Based on Ken Shirriff's IrsendDemo * Version 0.1 July, 2009 * * An IR LED circuit *MUST* be connected to ESP8266 pin 4 (D2). * * TL;DR: The IR LED needs to be driven by a transistor for a good result. * * Suggested circuit: * https://github.com/markszabo/IRremoteESP8266/wiki#ir-sending * * Common mistakes & tips: * * Don't just connect the IR LED directly to the pin, it won't * have enough current to drive the IR LED effectively. * * Make sure you have the IR LED polarity correct. * See: https://learn.sparkfun.com/tutorials/polarity/diode-and-led-polarity * * Typical digital camera/phones can be used to see if the IR LED is flashed. * Replace the IR LED with a normal LED if you don't have a digital camera * when debugging. * * Avoid using the following pins unless you really know what you are doing: * * Pin 0/D3: Can interfere with the boot/program mode & support circuits. * * Pin 1/TX/TXD0: Any serial transmissions from the ESP8266 will interfere. * * Pin 3/RX/RXD0: Any serial transmissions to the ESP8266 will interfere. * * ESP-01 modules are tricky. We suggest you use a module with more GPIOs * for your first time. e.g. ESP-12 etc. */ #ifndef UNIT_TEST #include #endif #include #include // Codes are in Global Cache format less the emitter ID and request ID. // These codes can be found in GC's Control Tower database. uint16_t Samsung_power_toggle[71] = { 38000, 1, 1, 170, 170, 20, 63, 20, 63, 20, 63, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 63, 20, 63, 20, 63, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 63, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 63, 20, 20, 20, 63, 20, 63, 20, 63, 20, 63, 20, 63, 20, 63, 20, 1798}; IRsend irsend(4); // An IR LED is controlled by GPIO pin 4 (D2) void setup() { irsend.begin(); Serial.begin(115200); } void loop() { Serial.println("Toggling power"); #if SEND_GLOBALCACHE irsend.sendGC(Samsung_power_toggle, 71); #else // SEND_GLOBALCACHE Serial.println("Can't send because SEND_GLOBALCACHE has been disabled."); #endif // SEND_GLOBALCACHE delay(10000); }
