It is an IC ie. 8255. it is used with in a combination with a microprocessor for the application of complex control algorithms. it is used coz of incapability of a micro-controller to achieve the same.....
The old workhorse 8255 PPI (Programmable Peripheral Interface) is a good place to start.
What interface that controls a peripheral device is.
C
So the link between the processor and the peripheral is complete :-)!
interface
Peripheral Component InterconnectSome times referred to as "Peripheral Component Interface" incorrectly.Hope this helps!
The interface between a computer and printer in which computer sends multiple bits signal to the printer.
peripheral interface controller
PRIMITIVE Operations.
HDMI is short for "High-Definition Multimedia Interface"
SCSI interface would be what you're looking for.
If the 82C55 programmable peripheral interface is not available, alternative options include using other programmable I/O chips like the 8255 PPI or microcontrollers with built-in I/O capabilities, such as those from the PIC or AVR families. Additionally, using GPIO (General Purpose Input/Output) pins on a microcontroller can fulfill similar functions, allowing for flexible control of peripherals. In some cases, FPGA (Field-Programmable Gate Array) solutions may be used to replicate the functionality of the 82C55.
