Embedded Technology and Keyboard with Display Multiplexing
Multiplexing refers to the use of configuring keyboards and displays in a matrix to bring down the number of I/O hardware lines being used. Without embedded technology, this is done by creating a matrix to bring down the total number of I/O lines used. The basic idea is that because of the basic nature of the human eye, it is possible to trick the brain into believing that the image is there even seconds after it has gone. If this image is constantly refreshed at a fast enough frequency, it can look stable. Traditional approaches to multiplexing can work theoretically, but for devices that require more digits, an exorbitant amount of power shall be needed in order to maintain a stable image.
Decoders can be used to reduce both I/O lines and overall computation and processing times. Embedded systems used in conjunction can reduce the number of I/O lines utilized for configuring keyboards and displays even further. Having an application designated for that purpose helps improve the overall capacity and efficiency of the keyboards and displays. Embedded technology makes it possible to leave behind the traditional methods in favor of cheaper, more efficient, grander capabilities of a dedicated software that strives for technological innovation.
