Abstract
A process for minimizing the software component and maximizing the hardware component of an infrared code includes separating the software component from the hardware component. The software component may be stored in memory, on a disk, accessed through a remote server, stored on the hard drive of a microprocessor, or the like. The hardware component may be implemented as a simple peripheral device, an outboard integrated circuit or imbedded within a processor or on a PC motherboard. The variable IR data, such as the bit modulation technique, the function data, and the protocol data, are stored in the software component. The software component configures and controls each IR transmission. The hardware component, which transmits the IR light for sending the infrared code, includes a pair of carrier cycle registers, a pair of bit modulation registers, and buffers to enable synchronous loading of frequency, duty cycle, cycle data, and wait time sent from the software component.
