IR Receiver for the I2C Bus

A commonly encountered problem is that the code sent by an infrared transmitter cannot be evaluated by a microcontroller directly on being received, due to the fact that the microcontroller is busy with something else at the time or is simply too slow to sample the signal at a rate sufficient to achieve an error-tolerant evaluation. In such cases, a helpful solution is to use a Philips SAA3049 infrared television decoder, which is still available as an NOS (new old stock) item although it is no longer being manufactured.
