The library leverages the BC7215A's ability to decode/transmit IR signal in arbitrary format, and can recognise and pair with any air conditioner with one click. \n\n**Relative Documents:**\n\n[BC7215A datasheets](./extras/doc/bc7215_en.pdf)\n\n[Schematic of the BC7215A IR transceiver board](./extras/doc/bc7215_arduino_board.pdf) \n\n![Demo application with ESP32](./extras/img/system_en.jpg)\n\nThis is the Arduino encapsulation of the same library's C version, making it work seamlessly with Arduino through simple function calls. The library supports key air conditioner operations: temperature adjustment, mode selection, fan speed control, and power on/off. It also supports parsing of the IR signal, read these settings form IR.\n\n2 manuals are provided:\n\n* [A/C Control Library User's Manual](./extras/doc/BC7215AC_arduino_ac_lib.pdf)\n\n* [User's Manual for built-in examples](./extras/doc/AC_control_examples.md)\n\nThough the library user's manual (pdf) available in the document directory provides more details, the best way to learn about this library is to follow the examples. There are 5 examples provided with the library, and each one has both English and Chinese versions:\n\n- **ESP8266 Serial Monitor Version**\n- ****ESP32 Serial Monitor Version****\n- ****Arduino Nano 33 IoT Serial Monitor Version****\n- ****ESP32 LCD Version****\n- ****ESP32 MQTT online IoT Version****\n- **ESP32 Home Assistant Example**\n- **ESP8266 Home Assistant Example**\n\nIt's recommended to start with the serial monitor examples to get familiar with the library functions, then progress to LCD and MQTT versions for more advanced integrations.\n\n\"**ESP8266 Serial Monitor Version**\" Using software serial for communication with the BC7215A and the Arduino IDE serial monitor for user interaction. It demonstrates all the features of this library. \n\n\"**ESP32 Serial Monitor Version**\" is port of the ESP8266 example, adapted for ESP32 hardware.\n\n**\"Arduino Nano 33 Iot Serial Monitor Version\"** is a port to the popular official board with ATMEL SAMD processor.\n\n\"**ESP32 LCD Version**\" utilize the LILYGO T-Display's onboard buttons and LCD for a user-friendly interface, demonstrating control without relying on a computer.\n\n\"**ESP32 MQTT IoT Version**\" extend the LCD version with networking capabilities, allowing MQTT-based remote control and status reporting for IoT applications.\n\n\"**ESP32/8266 Home Assistant Example**\" Can promote itself to Home Assistant and get Integrated automatically, then you can control the AC in HA immediately.\n\nPlease see [**A/C Control Examples**](./extras/doc/AC_control_examples.md) (markdown) for detailed information about the examples. Or the [**PDF version**](./extras/doc/AC_control_examples.pdf) if you prefer.\n\n## Other Documents:\n\nThis A/C remote control library comes with the BC7215 chip driver library as a low level driver,  Here are the relative documents:\n\n[**BC7215 CHIP DRIVER LIBRARY README FILE**](./extras/doc/README_BC7215_DRIVER.md)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbitcode-tech%2Fbc7215ac","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbitcode-tech%2Fbc7215ac","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbitcode-tech%2Fbc7215ac/lists"}
