How is the keycode calculated while interfacing a keyboard with a microprocessor?..

Answer / Puneet Kumar Kanoujia

The process of calculating keycodes for interfacing a keyboard with a microprocessor involves using a specific encoding scheme. The most common encoding schemes are ASCII, EBCDIC, and Scancodes.
In the case of Scancodes, each physical key on a keyboard is assigned a unique code or sequence of codes that correspond to its location and function. When a key is pressed, the microprocessor receives the associated scancode, which it then translates into an ASCII or other character based on the encoding scheme used.
