I²C transmits data between devices connected to the bus using only two lines (SDA and SCL). Each device is identified by a unique address (whether it is a microprocessor, LCD driver, memory, or keyboard interface) and can be used as a transmitter or receiver depending on the function of the device. The LCD driver may be just a receiver, and the memory can send and receive data. In addition to transmitters and receivers, the device can be used as a host or slave when transmitting data. The host i
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 chip in the official product is encrypted, A program cannot be read directly using a programmer. But sometimes customers for a number of reasons, need to get a single-chip internal progr
I2C transmits data between devices connected to the bus using only two wires (SDA and SCL. each device is identified by a unique address (whether it is a microprocessor, LCD driver, memory, or keyboard interface) and can be used as a sender or receiver based on the functions of the device. the LCD driver may be a receiver, while the memory can send and receive data. in addition to transmitters and receivers, the device can act as a host or slave when transmitting data.

Still remember when reading, the teacher said that single-chip computer, ARM, DSP has interoperability, are CPU, but listen to the teacher can not understand.How can I understand them and find out their similarities and differences? Let's take a look at my wife's views:Icer, SOC design for arm CPUsLet me say a few words, hoping to say a little thinner.First of all, said CPU, central processing unit, the essence is an integrated circuit, the function is to read out from a place (such as ROM) a co
SCM PIN, can be controlled by the program, output high, low level, these can be considered as the output voltage of the microcontroller.However, the output current of MCU is not controlled. The output current of the microcontroller is largely dependent on the external device on the PIN.Single-chip microcomputer output low-level, will allow the external device, to the single-chip microcomputer pin into the current, this current, called "Sink current",

Single-Chip Microcomputer microcontroller is widely used in embedded systems of various industries and civil applications due to its small size, low power consumption, and convenient use. With the rise and popularization of the Internet, it makes sense for the microcontroller to transmit data over the Internet. Currently, there are two solution
ARM Cortex-M Processor family is an energy-efficient and easy-to-use family of compatible processors designed to help developers meet the needs of future embedded applications. These needs include providing more functions, increasing connections, improving code reuse, and improving energy efficiency at a lower cost. Cortex-M series cost-and power-sensitive MCU and terminal applications (such as intelligent measurement, human-computer interface equipment, automotive and industrial control systems

Before just learning single-chip computer, after certain programming, can realize a lot of different functions, at that time, I feel that single-chip microcomputer is really a powerful. Later came into contact with DSP, found that DSP processing digital in communication, more convenient. So I was curious to ask myself, DSP and microcontroller, what is the difference:1. Different memory structureSingle-chip microcomputer using von Neumann memory struct
The first two days to learn the socket programming, in the big God to ask a question was rejected, there is a kind of have not learned to walk just want to run feeling. The great God said that my current level should be to do some like the operation of files, serial numbers and other small exercises to deepen understanding. Here's a little exercise he gave me:
