Blue chip stocksIt refers to a listed company with a large share capital and market value, but not all large-disk shares can be called blue-chip stocks. Therefore, it is difficult to set a definite standard for blue-chip stocks. From the experiences of various countries, companies with large market capitalization, stable performance, leading position in the indus

In a Linux operating system, there is a system software package, which features similar to "add and delete programs" in Windows, but features much better than "add and delete programs, it is RedHatPackageManager (RPM ). In a Linux operating system, there is a system software package, which functions similar to "add/delete programs" in Windows, but is much more powerful than "add/delete programs, it is Red Hat Package Manager (
In a Linux operating system, there is a system software package, which functions similar to "Add/delete programs" in Windows, but is much more powerful than "Add/delete programs, it is Red Hat Package Manager (RPM ). This toolkit was first launched by Red Hat and later borrowed by other Linux developers. Because it saves Linux users a lot of time, it is widely used to install and delete software in Linux. The following describes how to use it.1. We ge
South Bridge Chip (South Bridge)
It is an important part of the Motherboard chipset. Generally, it is located at the far bottom of the motherboard from the CPU slot, near the PCI slot. This layout takes into account the many I/O buses it connects, A little farther away from the processor is conducive to wiring. Compared with the North Bridge Chip, the data processing capacity is not large, so the south brid
What is Chip Decryption ? What is IC decryption ? What is a single-chip microcomputer decryption ? Brief description of Chip decryption: nbsp; Chip decryption is also known as a single-chip microcomputer decryption (IC decryption ) because the microcontroller
say this is a fine line, but the pro-test effect is good) The program generally uses ordinary monolithic microcomputer such as 51 series to produce 40kHz square wave, the inverter is used to enlarge the rectangular waves, echo detection using CX20106A chip. The reason is that the edge is because: Ultrasonic receiver circuit is mainly composed of cx20106a and ultrasonic transducer, cx20106a is a special infrared

This section describes how to identify the PIN numbers of an integrated circuit. Here we will briefly understand the specific functions of 40 pins of 51 single-chip microcomputer. Readers who have never been familiar with complex electronic components may feel very difficult, but they do not need to be afraid.

At the seminar, the two schemes were completely different. One uses a general chip, such as DSP, arm9-and FPGA, and one uses a dedicated chip, such as a copy, scan, and fax integrated chip. The two solutions have their own advantages and disadvantages:
The general-purpose chip has the following advantages:
1. It is eas
At the programme seminar, two programmes were very different. One uses a general-purpose chip, such as a DSP,ARM9,FPGA, a dedicated chip, such as a copy-and-scan facsimile integration. There are advantages and disadvantages to each of the two schemes:
Using a general-purpose chip, the advantages are:
1. Easy to buy chips. Not only depends on one model. Any MCU ca
circuit has obvious advantages. This is the root cause for the wide application of digital circuits.
The introduction of digital circuits ends here. More details will be provided in the principles section. In fact, the nature of single-chip microcomputer is also a digital circuit. The traditional digital circuit we want to talk about below refers to a digital circuit other than a single-chip microcomputer

Normalization is translated from normalization. The purpose of normalization is to make measurements under various/group measurements or under various experimental conditions can be compared with each other to eliminate non-experimental differences between measurements. Non-experimental differences may come from sample preparation, sample, hybridization, and signal p

I can see this question. A lot of people may need to hit the stone brother's board. What is the value of 7 + 5? How do you teach this? But in single-chip microcomputer, numbers are used

Even though we have not learned a command for teaching materials. However, I mean to do a few experiments first to increase your interest in single chip microcomputer.
The timer is a very important function for each MCU. To implement a precise timer, measure the frequency, and generate a PWM, the timer depends on the timer. The number of timer digits determines the timer precision, currently, we have encountered an 8-bit timer, a 16-bit timer, and a 32-bit timer. Features are more powerful than others. The higher the number of digits, the higher the accuracy of PWM, the more delicate the changes, easy to control. For at89x51, there are two timers T0 and T1, An
