* Example circuit diagram: | |
* https://github.com/crankyoldgit/IRremoteESP8266/wiki#ir-receiving | |

* Changes: | |
* Version 1.2 October, 2020 | |
* - Enable easy setting of the decoding tolerance value. | |
* Version 1.0 October, 2019 | |
* - Internationalisation (i18n) support. | |
* - Stop displaying the legacy raw timing info. | |
* Version 0.5 June, 2019 | |
* - Move A/C description to IRac.cpp. | |
* Version 0.4 July, 2018 | |
* - Minor improvements and more A/C unit support. | |
* Version 0.3 November, 2017 | |
* - Support for A/C decoding for some protocols. | |
* Version 0.2 April, 2017 | |
* - Decode from a copy of the data so we can start capturing faster thus | |
* reduce the likelihood of miscaptures. | |
* Based on Ken Shirriff's IrsendDemo Version 0.1 July, 2009, | |

// ==================== start of TUNEABLE PARAMETERS ==================== | |
// An IR detector/demodulator is connected to GPIO pin 14 | |
// e.g. D5 on a NodeMCU board. | |
// Note: GPIO 16 won't work on the ESP8266 as it does not have interrupts. | |
// Note: GPIO 14 won't work on the ESP32-C3 as it causes the board to reboot. | |
#ifdef ARDUINO_ESP32C3_DEV | |
const uint16_t kRecvPin = 10; // 14 on a ESP32-C3 causes a boot loop. | |
#else // ARDUINO_ESP32C3_DEV | |
const uint16_t kRecvPin = 5; //14; | |
#endif // ARDUINO_ESP32C3_DEV | |
// The Serial connection baud rate. | |
// i.e. Status message will be sent to the PC at this baud rate. | |
// Try to avoid slow speeds like 9600, as you will miss messages and | |
// cause other problems. 115200 (or faster) is recommended. | |
// NOTE: Make sure you set your Serial Monitor to the same speed. | |
const uint32_t kBaudRate = 115200; | |
// As this program is a special purpose capture/decoder, let us use a larger | |
// than normal buffer so we can handle Air Conditioner remote codes. | |
const uint16_t kCaptureBufferSize = 1024; | |
// kTimeout is the Nr. of milli-Seconds of no-more-data before we consider a | |
// message ended. | |
// This parameter is an interesting trade-off. The longer the timeout, the more | |
// complex a message it can capture. e.g. Some device protocols will send | |
// multiple message packets in quick succession, like Air Conditioner remotes. | |
// Air Coniditioner protocols often have a considerable gap (20-40+ms) between | |
// packets. | |
// The downside of a large timeout value is a lot of less complex protocols | |
// send multiple messages when the remote's button is held down. The gap between | |
// them is often also around 20+ms. This can result in the raw data be 2-3+ | |
// times larger than needed as it has captured 2-3+ messages in a single | |
// capture. Setting a low timeout value can resolve this. | |
// So, choosing the best kTimeout value for your use particular case is | |
// quite nuanced. Good luck and happy hunting. | |
// NOTE: Don't exceed kMaxTimeoutMs. Typically 130ms. | |
#if DECODE_AC | |
// Some A/C units have gaps in their protocols of ~40ms. e.g. Kelvinator | |
// A value this large may swallow repeats of some protocols | |
const uint8_t kTimeout = 50; | |
#else // DECODE_AC | |
// Suits most messages, while not swallowing many repeats. | |
const uint8_t kTimeout = 15; | |
#endif // DECODE_AC | |
// Alternatives: | |
// const uint8_t kTimeout = 90; | |
// Suits messages with big gaps like XMP-1 & some aircon units, but can | |
// accidentally swallow repeated messages in the rawData[] output. | |
// | |
// const uint8_t kTimeout = kMaxTimeoutMs; | |
// This will set it to our currently allowed maximum. | |
// Values this high are problematic because it is roughly the typical boundary | |
// where most messages repeat. | |
// e.g. It will stop decoding a message and start sending it to serial at | |
// precisely the time when the next message is likely to be transmitted, | |
// and may miss it. | |
// Set the smallest sized "UNKNOWN" message packets we actually care about. | |
// This value helps reduce the false-positive detection rate of IR background | |
// noise as real messages. The chances of background IR noise getting detected | |
// as a message increases with the length of the kTimeout value. (See above) | |
// The downside of setting this message too large is you can miss some valid | |
// short messages for protocols that this library doesn't yet decode. | |
// | |
// Set higher if you get lots of random short UNKNOWN messages when nothing | |
// should be sending a message. | |
// Set lower if you are sure your setup is working, but it doesn't see messages | |
// from your device. (e.g. Other IR remotes work.) | |
// NOTE: Set this value very high to effectively turn off UNKNOWN detection. | |
const uint16_t kMinUnknownSize = 12; | |
// How much percentage lee way do we give to incoming signals in order to match | |
// it? | |
// e.g. +/- 25% (default) to an expected value of 500 would mean matching a | |
// value between 375 & 625 inclusive. | |
// Note: Default is 25(%). Going to a value >= 50(%) will cause some protocols | |
// to no longer match correctly. In normal situations you probably do not | |
// need to adjust this value. Typically that's when the library detects | |
// your remote's message some of the time, but not all of the time. | |
const uint8_t kTolerancePercentage = kTolerance; // kTolerance is normally 25% | |
// Legacy (No longer supported!) | |
// | |
// Change to `true` if you miss/need the old "Raw Timing[]" display. | |
