Suppose you connected a high-level keyboard and two 7 segment displays to the interfacing IC 82C55. a) Write the 8 bit configuration to configure the IC for the above scenario. b) If you want to display the last 2 digits of your student ID in the 7 segment displays, then draw the diagram and describe the working mechanism for that mentioning all the transistors and pin values. c) In another scenario, you want to show the first character of your Name in an LED Matrix display. Explain the step by step process of how the microcontroller would send the data to the display device and the mechanism of the device.
