diagram)There may be differences between the clock trees on STM32 for different series of chips. F0, F1 and F3 series chips (the mainstream chip, the frequency is relatively low) there are many similarities, F2 and F4 (high-performance chip) series of chips have many similar places. However, there is a big difference between the clock trees of the F3 chip and th

Recently many users consulted w3100a, because w3100a has been discontinued. In this hope to introduce you, w3100a can be transplanted to other chips and ways, for you to better expand the use of your project, look forward to help you. Let me introduce you to the first part of the article today.This porting note describes the issues that designers and programmers should pay attention to during the w3100a to w3150a+ migration. For more information on w3

I have summarized two types of chips: master and slave ). This method is just for convenience. Okay. Let's take a look at the master. Generally, this role can be called a SoC (system on chip), that is, a system-level chip. SOC can be divided into three types: MCU (micro control unit), MPU (micro processor unit), and DSP (DSP, there is no clear line between MPU and MCU, but I think this distinction is still very necessary. Let's first look at a MCU man

The serial port of 51 chips can work in several different working modes. The working mode is set to use the scon register. The specific definitions of its bits are as follows:Sm0 SM1 SM2 Ren tb8 rb8 Ti riSm0 and SM1 are bits in the working mode of the serial port, so that the two can be set in four modes. Set the working mode of the serial port. When using the serial port for communication, a very important parameter is the baud rate. normal communic

necessary to use this software to simulate the target CPU to verify the code logic.● It is an effective tool for learning embedded development. It frees learners from the underlying hardware details and focuses on software, especially System Software unrelated to specific hardware (TCP/IP protocol stack ). Several good hardware simulation platforms: ● Skyeye: Chen yufa, a postdoctoral fellow in the computer department of Tsinghua University, is an open-source project that mainly simulates the A

stocks, even if the stock is not seriously undersold or underopened, this opportunity can be taken when the stock shows a significant upward trend in the intraday performance, buy the same number of stocks. After the stock rises to a certain height, sell all the stocks of the same type of stock that was originally set, so that you can buy and sell the same stock in one trading day, to get the difference profit.3. If the stock held by an investor is not locked, but is profitable, T + 0 can be us

computers, the data stored by users often far exceeds the computer's own price. When the cost is relatively small, RAID technology can enable individual users to enjoy doubled disk speed and higher data security, the IDE-RAID control chips on the PC market are mainly from highpoint and promise, and some are from AMI companies (such as table 2 ). IDE-RAID chips for individual users generally only support RA

Seven required courses in the entrepreneurial age Chapter 1 seven required courses in the entrepreneurial age We cannot use our eyes and fingers to find iron chips in the middle of a pile of sand, just as it is difficult for us to find our customers from the vast sea of people. However, there is a tool that can help us quickly find iron chips in the sand ...... Lesson 1 fate is an e falling into the nest Wo

Due to the demand of the information market and the development of microelectronics, the feature size of the integrated circuit is constantly reduced.Small) is the main feature of the development of a variety of process integration technologies and application-oriented system-level chips.

Clear dust Dust floating in the air is a major killer of computers. After using it for a while, it may cause a fault due to the dust accumulation of key components such as the motherboard, even in a dedicated equipment room. Therefore, the computer that has been used for a long time should be cleaned first, and the dust on the motherboard and peripher

North Bridge, South Bridge is the most important two on the Motherboard chipset. they are all bus controllers. they are bus control chips. relatively speaking, the North Bridge is more important than the south bridge. the North bridge connects to the system bus and is responsible for CPU access to memory. at the same time, this AGP plug-in is connected to control the PCI bus, and the system bus and local bus are cut off. The speed is the fastest in th

Once a single change shows the value of the returned value below the first step, you can abort the search immediately.　 We don't need to know exactly how bad the second move is, and the program will definitely choose the first move.

The Serial Peripherals Interface (serial peripheral INTERFACE,SPI) is developed by Motorola to provide a low-cost, Easy-to-use interface between microcontrollers and peripheral chips (SPI is sometimes referred to as a 4-line interface). This interface can be used to connect memory, Ad/da converters, real-time clock calendars, LCD drives, sensors, audio chips, and even other processors. Currently, there are

How many cores do you have on your phone? This is one of our most frequently asked questions when comparing the two phone differences. The number of CPU cores is indeed an important indicator of the performance of a mobile phone, but it is not the most accurate indicator.Take the most common Qualcomm Snapdragon in the market, for example, in the entire "processor", the CPU portion only accounted for 15% of the chip area, the other 85% is the image Processor (GPU), Digital signal Processor (DSP),
