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

In fact, learning single-chip computer This kind of thing is not what single-chip computer learning Forum, first look at the information books, and then practice, if you encounter any problem can not solve the online search for information, on the network on the single-chip microcomputer frequently asked questions are very many, how to pick out the answer you nee
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
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
The single chip microcomputer multi-byte serial port receive (high-order research of serial port multi-byte receive send)Original address: Http://bbs.ednchina.com/BLOG_ARTICLE_3007162.HTMWork for more than a year, wrote a lot of single-chip computer serial program. The sense of the serial port multi-byte receive part of the logic relative to the configuration register with the serial port reply, is a bit di
Single-chip microcomputer tutorial 4. C Language Foundation and realization of running lightsC language, people who have not touched the computer programming language will see it very mysterious, it feels very difficult, and in my opinion, C language logic and operations, is the primary level, so we do not fear it, I as far as possible from the primary mathematical logic way with everyone to learn C language. 1.1 binary, decimal, and hexadecimalSeemin
What is a U disk's main control chip? use a U disk to mass production are aware that the first step is to test the U disk's main control chip is what, and then according to the corresponding tool for mass production. The net summarizes, the user uses most the main control chip is the group union Phison and the Skymedi. Now let's take a look at their pros and cons
Generally, the microcomputer (PC) is composed of the Main Board, CPU, memory, hard disk, and other devices, the single-chip microcomputer means that these devices are integrated into one chip (or some of them are implemented through external chip Extension). The single-chip microcomputer is also called a microcontrolle
