I found a program to send data through the serial port of FPGA. Why does it only work at 9600 baud rate? When I change the parameters to other baud rates, whether 4800 or 115200, it doesn't work and I...
I received the ESP8266 MPY board, looked at the information and started to work. I first installed the driver, updated the firmware to 1.8.3, and followed the official tutorial to learn. Execute [colo...
Hey guys, I have a question, why is my circuit connected to the simulator fine, but after simulating and burning the program several times, the power and ground of the chip are short-circuited, and bo...
I was lucky enough to win a Xiaomi bracelet last time, which was shipped by JD.com. I don’t have an invoice, so how do I handle the subsequent warranty?...
I saw a camera solution made by someone else. It used the MI-SOC360 CMOS chip and paired it with Sonix sn9c211. MI-SOC360 is PLCC28-pin, and SN9C211 is LQFP48-pin. I searched for a long time on the In...
I saw an interesting complaint somewhere else. I'll share it with you. Life is like drawing a PCB. 1. Layout first, then routing. No matter how detailed the routing is, it's useless if the layout fail...
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
Editor's note: In order to help technicians or engineers who have knowledge of PIC microcontroller assembly language quickly master the method of using C language to program PIC microcontrollers, t...[Details]
A multi-point temperature control heating control system was designed using the SST89E564RC single-chip microcomputer and a new temperature measuring device. The heating system can be controlled in...[Details]

1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
When the so-called "copycat phones" that flood the domestic mobile phone market move towards large screens, stereo amplifiers, touch controls, and even GPS navigation and mobile TV, the homogeneity...[Details]
1 Introduction
Power supply ripple will interfere with the normal operation of electronic equipment, causing malfunctions such as computer crashes, data processing errors and control system fa...[Details]
1. Introduction
Stepper motor is a basic component that converts electrical energy into kinetic energy. It has been widely used in a variety of electromechanical equipment, such as various machine...[Details]
Any power transmission and distribution equipment and power-consuming devices cannot be pure resistive loads, so they must occupy a certain amount of reactive power. The existence of reactive curre...[Details]
1 Theoretical Analysis
Ultrasonic waves
When propagating in a suspension, the ultrasonic waves that encounter the suspended particles are scattered and attenuated at the interface, an...[Details]
This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]
Background
The proliferation of ultra-low-power wireless sensor nodes for measurement and control purposes, combined with new energy harvesting techniques, has made it possible to create ful...[Details]
