单片机中按键的英文缩写(单片机按键控制数码管显示0到9)

Introduction

Single chip microcontroller or microprocessors are commonly used in numerous applications, including industrial machines, robotics, household appliances, and electronic devices. These microcontrollers utilize various input and output devices to interact with the user or the external environment. In this article, we will talk about one of the most common types of input devices used in microcontrollers - the keypad. More specifically, we'll discuss the abbreviations used for the keypad in the microcontroller world.

The Basic Functionality of Microcontroller Keypads

A keypad is a type of input device consisting of several buttons or keys that can be pressed to input data into the microcontroller. There are two types of keypads: matrix and single-key. In a matrix keypad, buttons are arranged in rows and columns, and each button represents a unique combination of a row and a column. By pressing a button, the microcontroller detects the respective row and column and determines the key's value. On the other hand, a single-key keypad is a push-button that represents a single input. Depending on the application, microcontrollers use different abbreviations for the keypad.

Microcontroller Abbreviations for Keypad

The most commonly used abbreviations for the keypad in microcontrollers are KP (Keypad), KB (Keyboard), and KBD (Keypad Display). The term KP is generally used to control external keypads that include all types of single-key and matrix keypads. It is essential to note that microcontrollers often have specific instructions to work with a particular type of keypad. The system may require unique pins and protocols to connect with the keypad. Therefore, understanding the abbreviation is crucial for identifying how to interface with the keypad properly.

In contrast, KB is a more generic term that encompasses all types of input devices with keys or buttons in the microcontroller. It includes not only keypads but also a wide range of input devices such as USB keyboards, touchpads, and gamepad controllers. The abbreviation KBD, or Keypad Display, is a more advanced type of keypad that includes an integrated display. This display can either show the entered characters or result from the output of a certain operation based on the entered input.

Conclusion

In summary, microcontrollers use abbreviations for the keypads to identify and differentiate the different types of input devices used in specific applications. KP, KB, KBD are the most commonly used abbreviations for microcontroller keypads. While KP is used to control and manage external keypad devices, KB and KBD are more generic terms that cover all types of input devices that have keys or buttons. Understanding these abbreviations is crucial for interfacing with the keypad and ensuring appropriate functionality in the required application.
