, the output end is equivalent to floating (no current flow), and its level varies with the external level, that is, the circuit gives up the control of the output end circuit. Typical applications: 1,In the structure of the bus connection. There are multiple devices mounted on the bus, and the devices are connected to the bus in the form of high resistance. In this way, the bus is automatically released when the device does not occupy the bus to facilitate other devices to obtain the right to

programmed in the Arduino programming language, compiled into a binary file, and burned into a microcontroller. The Arduino programming is implemented using the Arduino programming language (based on Wiring) and the Arduino development environment (based on processing). Arduino-based projects can include only Arduino, and some other software that runs on the PC, such as Flash, processing, MaxMSP. Foreign names Arduino Founder Ma

I am a graduate of the 08 Huizhou College of Electronics, now engaged in embedded research and development of Linux. I write this so-called "embedded Learning Method", is because the beginning of learning embedded, the electronic system almost no one can bring their own to get started or teach related learning methods, basically are their own groping to learn, can imagine, the process of the pain of the level of people want to die. So hope that through the year to their own study, sorting out a

the ordinary programmer, which is called single-chip microcomputer encryption or chip encryption. Single-chip computer attackers with special equipment or self-made equipment, the use of single chip microcomputer chip design loopholes or software defects, through a variety of technical means, can be extracted from the chip key information, to obtain a single-chip computer program This is called Chip decryption. Chip decryption is also known as single-chip microcomputer decryption, single-chip

-impedance state: When the circuit is analyzed, it can be opened. You can think of it as a very large output (input) resistor. His limits can be thought of as dangling. That is, the theoretical high impedance is not suspended, it is to the ground or to the power of a large state of resistance. The actual application is the same as the pin dangling.(When the output of the gate circuit slide on the slide cutoff, the output is high, the reverse is low level, if the upper slide and lower slide are c

In embedded system, we usually use the keyword "volatile", what does the keyword mean?AnalysisThe main purpose of the volatile modifier is to prompt the compiler that the value of the object may be changed without the compiler being monitored, so the compiler cannot arbitrarily optimize the code for that object.A simple compiler optimizer1) Read the value of variable a into register X, as long as the X value is not changed, and later need to use the value of a to read from XThe role of volatile1

CTRL-S Suspend (XOFF), hangs. This is the stdin that freezes the terminal. To recover can press CTRL - Q . CTRL-T Swaps the character contents of the cursor position with the previous position of the cursor (at the command line). For example echo $var; , assuming that

, I thought of a way to improve on this basis, because the previous PWM duty ratio is constant, so it is difficult to achieve satisfactory results, the current method is that the root of the motor is twisted angle, or the size of the encoder count value to adjust the PWM duty ratio, Encoder count Value Deviation 0 more (positive or negative greater), PWM duty ratio is greater, the strength of the motor is greater, so that the motor will not appear as soon as the maximum speed to turn back to the

I know that the I2C of stm32 is not easy to use, because I have used analog I2C, and I have also written the AVR I2C, that is, the twi hardware driver, so I want to try writing stm32 hardware I2C... In order to avoid the trouble caused by the Library, the standard
