IrCode Finder NEC protocol

Discover the IrCode Finder NEC protocol, a versatile tool designed to assist you in finding the correct infrared (IR) codes for your devices. This app boasts an extensive database of remote control codes, ensuring that you can conveniently locate the right match for a variety of appliances such as chandeliers, fans, acoustics, and other simple devices. Its utility shines when handling products that have been on the market for an extended period, potentially facilitating the replacement of lost or dysfunctional remotes.

For those instances where your specific device code is not readily available, the platform facilitates an automatic testing function to identify the appropriate IR codes within the NEC protocol. For successful operation, it's worth noting that your device should be equipped with an IR transmitter.

IrCode Finder NEC Protocol

The IrCode Finder NEC protocol is a communication protocol used to transmit infrared (IR) signals between devices such as remote controls and TVs. It is a widely used protocol, especially in consumer electronics.

The NEC protocol uses a pulse width modulation (PWM) scheme to encode data. The data is transmitted as a series of pulses, with the width of each pulse representing a binary value. The protocol uses a start bit, data bits, and a stop bit to frame the data.

The start bit is a short pulse, typically 900 microseconds long. The data bits are longer pulses, typically 1.6 milliseconds long. The stop bit is a long pulse, typically 2.25 milliseconds long.

The data bits are transmitted in groups of four, with each group representing a hexadecimal digit. The first four bits represent the high nibble of the digit, and the second four bits represent the low nibble.

The NEC protocol also uses a checksum to ensure that the data is transmitted correctly. The checksum is calculated by adding up the values of the data bits and then taking the two's complement of the result. The checksum is transmitted as the last four bits of the data.

The IrCode Finder NEC protocol is a simple and reliable protocol that is well-suited for use in consumer electronics. It is widely supported by both hardware and software, making it easy to use in a variety of applications.
