The Introduction of Single-Chip Microcomputer and Digital Tube

The single-chip microcomputer, also known as the microcontroller, has been widely used in our day-to-day life. It is a kind of integrated circuit that integrates the central processing unit (CPU), input/output ports, memory, and other peripheral circuits on a single chip. The digital tube, also known as the numeric display tube, is a type of electronic device used for displaying numbers. It is widely used in electronic products that require numerical reporting, such as calculators, electronic clocks, etc. This article will introduce the English name of the digital tube used by the single-chip microcomputer, aiming to help those who want to learn or use single-chip microcomputers.

The Classification of Digital Tube

There are various types of digital tubes, and they are divided into two categories: common anode and common cathode. The common anode digital tube is a type of digital tube that requires a voltage signal on the pole of a common anode to light up individual components. The common cathode digital tube is the opposite of the common anode digital tube, which requires grounding on the pole of a common cathode to activate individual components. Additionally, the digital tubes are further divided into two categories: 7-segment digital tubes and Dot Matrix digital tubes. 7-segment digital tubes are more commonly seen in everyday life, while Dot Matrix digital tubes are mainly used in high-end electronic products.

The English Name and Addressing Method of 7-Segment Digital Tube

The English name of the 7-segment digital tube is 7-Segment LED Display. The basic unit of the 7-segment digital tube is a seven-segment display, which is a device that can display numbers by lighting up specific segments of the seven-bar patterns. The addressing method of the 7-segment digital tube used by the single-chip microcomputer usually uses the positive logic code. The positive logic code indicates that when a signal is applied to a specific bit, the corresponding digital tube lights up. For example, in three 7-segment digital tubes connected with a single-chip microcomputer, if the signal of 0x12 is transmitted to the digital tube in turn, then the single-chip microcomputer circuit can control the digital tubes to display 012.

In conclusion, the digital tube used by the single-chip microcomputer has many types, and it can be divided into common anode, common cathode, 7-segment, and Dot Matrix digital tubes. The English name of the 7-segment digital tube is 7-Segment LED Display, and the addressing method of the 7-segment digital tube used by the single-chip microcomputer commonly uses the positive logic code. Understanding the digital tube and how it can be controlled by the single-chip microcomputer is an essential part of mastering the application of single-chip microcomputers.
