The application of EDA and single-chip technology on the keyboard In order to further study EDA technology and single-chip technology, the following will analyze the application of EDA technology and single-chip technology in the keyboard to more effectively improve the technical level of software development and promote software development The long-term development of the industry. In the study of the application of EDA technology and SCM technology on the keyboard, EDA related software and programming download software, as well as the corresponding SCM and supporting compiling software are used. The keyboard is generally a matrix keyboard, which has a wide range of practicability.
In the keyboard setting, the keys are set by the focus of the row line and the column line, and the two ends of the key switch are connected to the row line and the column line respectively. The row line is connected through a pull-up resistor. Therefore, in the absence of any operation, the row line is at a high level. When a key operation is performed, the column line will affect the level of the row line, causing the column line Changes in level. The level of the row line changes with the level of the column line. If the column line is high, the row line is high. This point is used in the recognition of the button.
According to the basis of the key arrangement in the keyboard, when using EDA technology and single-chip technology, the column line and row line of the matrix keyboard are shared by multiple keys, which reduces the amount of chip I/O interface and greatly improves the speed of the keyboard. . In the keyboard, EDA technology and single-chip technology are used to connect the signals. When the row line and the column line affect each other, the keys can be effectively controlled and the keys can be closed. At the same time, through the combined application of EDA technology and single-chip technology, the switch of the keyboard can be effectively controlled, and the keyboard can be operated at any time, so as to complete the corresponding work according to the relevant instructions.
The application of EDA technology and single-chip technology on the keyboard can help the keyboard complete a variety of complex operations to achieve effective control of the screen display, thereby switching between different screens and completing different tasks. The promotion and application of EDA technology and single-chip technology in various industries provides a reliable guarantee for the continuous improvement of economic benefits of various industries, promotes the long-term development of my country's software industry, and is of great significance for promoting my country's socialist modernization.
The 7-inch tablet can be used as the golden size of a tablet computer. It is small and portable. It can be used at home and outdoors. You can browse the web, watch videos and play games. It is a household artifact. Although the size of the 7-inch tablet is inclined to the tablet, the function is more inclined to the mobile phone, so it can also be used as a substitute for the mobile phone. Compared with other sized tablets, the 7-inch tablet has obvious advantages in appearance and weight. Both the body size and the body weight have reached a very reasonable amount.
1.In appearance, the 7 inch tablet computer looks like a large-screen mobile phone, or more like a separate LCD screen.
