Circuit protection is everywhere in design. I seldom design circuits, and even in applications, I seldom consider circuit protection. I think the internal design of chips is basically very comprehensi...
Teachers, I would like to ask what is the specific role of the Schottky diode in the circuit? Because I can't see it clearly when I search on Baidu~ Thank you teachers...
Hello everyone: I have something to ask again. Both in PB and eVC++, there is a remote debugging function. Question: How can I establish a remote connection? I have tried using ActiveSync, I think it ...
I designed an LM358 amplifier circuit, as shown in the figure. I input a 1KHZ sine wave into the oscilloscope, but after I connected the signal generator to the lower end of R1, I used the oscilloscop...

Wang Xiaochuan, the "Wudaokou Goalkeeper", is going through a level that he has never gone through before. For example, Sogou's (NYSE: SOGO) financial report, artificial intelligence, and the futur...[Details]
【JDPCB】Qisda is introducing smart factories in phases. Chairman Chen Qihong said yesterday (25th) that through high automation, order delivery can be accelerated. The current benefits have reached a...[Details]
1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[Details]
Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]
This routine is also a classic routine on the development board. I modified the framework of the program to make it more suitable for future calls. The specific 4*4 keyboard scanning principle is rel...[Details]
When Amazon quietly launched a product called Elastic Computing Cloud 12 years ago, the Internet industry in China, across the ocean, also ushered in an unprecedented development opportunity. Let's...[Details]
Household photovoltaic power stations mainly utilize idle resources on existing household buildings, such as roofs, wall facades, balconies, courtyards, etc., to install and use distributed photovo...[Details]
Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
Here is the temperature added in the previous chapter The above figure is the temperature calculation formula: where Vsense is the ADC value collected from the temperature channel. The stm32f407 ...[Details]
Design a second and minute pulse generator for a single-chip microcomputer using the interrupt method. Assume that P1.0 generates a positive pulse of one machine cycle per second, and P1.1 generates ...[Details]
Circuit: Using AT89S52 single chip microcomputer. P3.0 to P3.3 are connected to four external buttons. P3.4 to P3.7 are the bit selection ports for controlling the four digital tubes, and P1 is the s...[Details]
Assume that the MCS-51 microcontroller uses a 12MHz crystal oscillator, and wants to use a timer to generate a pulse with a duty cycle of about 30% and a period of 60ms at port P1.0. ;==============...[Details]
