/* * IRremoteESP8266: IRsendDemo - demonstrates sending IR codes with IRsend * Version 0.1 June, 2015 * Based on Ken Shirriff's IrsendDemo Version 0.1 July, 2009, Copyright 2009 Ken Shirriff, http://arcfn.com * JVC and Panasonic protocol added by Kristian Lauszus (Thanks to zenwheel and other people at the original blog post) * * An IR LED circuit *MUST* be connected to the ESP8266 on a pin * as specified by kIrLed below. * * TL;DR: The IR LED needs to be driven by a transistor for a good result. * * Suggested circuit: * https://github.com/crankyoldgit/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. */ #include #include #include const uint16_t kPanasonicAddress = 0x4004; // Panasonic address (Pre data) const uint32_t kPanasonicPower = 0x100BCBD; // Panasonic Power button const uint16_t kJVCPower = 0xC5E8; const uint16_t kIrLed = 4; // ESP8266 GPIO pin to use.
