Background
Infrared (IR) receivers typically use a photo-diode to convert IR light into an electrical signal that can be processed by a micro-controller. Common applications include continuous data communication and consumer remote control systems.
IrDA is the standard used for continuous data transmission applications; however, the receiver/transceiver device must be IrDA compatible. The standard mode for IrDA, serial Infrared (SIR), allows serial data to be transmitted or received through standard UART.
For consumer IR remote applications, commonly used data formats include: 1. Bi-phase Encoding (ie. RC-5, RC-6) 2. Pulse Distance Encoding (ie. NEC) 3. Pulse Length Encoding (ie. SIRC)
More information regarding these three data formats can be found here. Additionally LIRC contains a large database of remote control codes.
Overview
The InfraredReceiver interface should be inherited by communication drivers
responsible for receiving IR data.

API
namespace sjsu
{
class InfraredReceiver
{
public:
using DataReceivedHandler = std::function<void(const DataFrame_t *)>;
virtual Status Initialize() const = 0;
virtual void SetInterruptCallback(DataReceivedHandler handler) const = 0;
};
}
Status Initialize() const;
Initialize performs the necessary initialization sequence to initialize the
device and returns Status::kSuccess upon successful initialization. If the
device fails to be initialized, the appropriate failure Status is returned.
virtual void SetInterruptCallback(DataReceivedHandler handler) const = 0;
SetInterruptCallback sets the interrupt callback handler that is invoked when
a new data is successfully received.
