http://blog.csdn.net/sdwuyulunbi/article/details/6632382Believe that a lot of people on the microcontroller and computer or chip communication, RXD and txd How to connect more confused. Because in some circuit diagram, there are some direct connection method, there are some cross-linking method, let a person a bit puzzled.The first thing to understand is the two concepts, DTE and DCE. DTE refers to data terminal equipment, the typical DTE is a compute

Let's talk about the memory Compilation Method in the computer today. For the computer's internal chip, People split it by bit. Let's take the following chip for example: Memory preparation There are 8x4 = 32 squares in the picture, that is, 32 bits. The following four lines are data lines used to retrieve data from the chip. When the

In addition to CPU sockets, various slots and interfaces, the motherboard also has many chips. In addition to the Motherboard chipset, most of the other larger chips are functional chips, which provide some specific functions for the motherboard. 1. BIOS chip The motherboard has a very important chip-BIOS chip. It is a flash memory

In MP3 this project, in addition to the decoding module, the most important is the U disk read and write module, we need to send music through the U disk to the microcontroller, and then output, and in this module we choose the CH375 this chip. Similarly, because the project is still in the hardware circuit production phase, today can only briefly introduce some of its functions and its connection, the specific software read and write in detail later.

The firmware upgrade instance of ms6000 chip with melfas describes the installation process of image files in the general array format. The chip requires a pin combination to complete a certain sequence and enable a set of command codes to enter the burning mode, in the burning mode, the I2C address is 0xfa (different from the address 0x40 when the chip works nor

mt6575 Chip is an excellent evaluation in the industry chip, its excellent performance parameters and practical user experience makes the mt6575 chip has become a reputation and cost-effective representative. Then you may want to follow the small together to learn a few about the mt6575 chip related information, we wil

recently, is learning ARM, so casually learn a single-chip microcomputer, to help understand. as mentioned in "Arm Learning note entry", embedded processors are divided into three types: embedded microprocessors, embedded microcontrollers,Embedded microcontroller is a microcontroller, it will CPU, memory and other peripherals are packaged together. 80C51 Series: 80C51 is a typical species in the MCS-51 series, and the CMOS process microcontroller pro

Today in the group there is a Netizen mentioned 51 single-chip computer using printf why the compilation passed, but no effect. Here to share my notes, the experiment itself does not make much sense, mainly to record 51 how the single-chip microcomputer should use the printf function.Experiment Name: Serial communication single chip microcomputer and PC calculati

MT8389 is a stranger to everyone, but if I say MT6589, I guess everyone understands it. In fact, MT8389 is a branch of MT6589, and a clone branch makes it clearer, is MT6589 high-consumption version. It can also be seen as the same CPU. I think it is necessary to popularize the basic knowledge of MTK CPU before explaining MT8389, because the CPU development of MTK has a great continuity, for example, the smartphone chip contains the function mobile ph

In wireless communication, the nrf24l01 wireless transceiver module produced by Nordic is the choice of many players. It is GHz ~ The single-chip wireless transceiver chip in the GHz ISM band has the advantages of strong functions, convenient control, and low price. One piece of nrf24l01 can receive data sent from six channels at the same time, and change the communication channel to avoid wireless communic

I am about to go out and look for a job. I don't know if I can use single chip microcomputer in the future. I will summarize my self-taught opinions. This gives beginners and fans a deeper understanding! The sequence of introduction is probably AVR, MSP430, and lpc210x. 51 Single-Chip Microcomputer I/O is bidirectional, and the drive capability is relatively weak. We generally use 51 single-

Linux AT90S8515 Single-Chip GCC programming lighting experiment documentary-Linux general technology-Linux programming and kernel information, the following is a detailed reading. Watching the Light Emitting Diode flash, I'm so happy. Success! For a newbie, this is the first time that we will never forget. ...... I have heard of avr in the csdn forum and downloaded programming and other things. When I searched for related information online, I found a

Differences between single-chip I/O port push-pull output and open-drain output) Push-pull output: outputs high and low levels and connects to digital devices; Open-drain output: the output end is equivalent to the collector of the transistor. To obtain a high-level state, the output end must be able to pull up the resistor. It is suitable for current-type drive and has a strong ability to absorb the current (generally less than 20 mA ).The push-pul

Previously just learned single-chip computer, after a set of programming, can achieve a lot of different functions, at that time, it is felt that single-chip microcomputer is really 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 differenceSee a forum on the DSP and the diffe
