With the ready availability of inexpensive microcontroller chips, many remotes may be based on such chips today rather than dedicated remote control encoder chips.
What is nuvoton cir transceiver driver code#
The code listings inform about for any universal remote. Manufacturers of consumer appliances often reuse the same protocol on many similar devices, though for each manufacturer and device type there are usually multiple protocols in use. Similarities between remotes are often largely the accidental result of the finite selection of infrared encoder/decoder chips (though now microcontrollers are also used) and IR receiver modules or imitation of the older chips rather than by design. Since the consumer IR protocols are for the most part not standardized, computers and universal remotes often memorize a bit stream, possibly with compression and possibly without determining the actual bit rate, and play it back. The type, speed, bandwidth, and power of the transmitted information depends on the particular CIR protocol employed.ĬIR is the most common type of free-space optical communication. For instance, a television remote control can convey a "channel up" command to the television, while a computer might be able to surf the internet solely via CIR. The functionality of CIR is as broad as the consumer electronics that carry it. CIR ports are commonly found in consumer electronics devices such as television remote controls, PDAs, laptops, and computers.
