The author built a minimum system with STC89C51 as shown below. The power supply uses the chip LM2940 to convert the 8V voltage into 5V and then power the microcontroller, and P2.7 is used to control ...
I did a CAN test on STM32F103VBT6, using TI's VP230 driver. The voltage on pin 230 is correct. The high-speed mode and slope control mode are not working. The program is fine because the same program ...
Because the IO of the microcontroller is 5V, and the sensor signal is 24V, I hope that the sensor can cut off the signal of the optocoupler while the IO controls the optocoupler. Because the IO of the...
Question: When downloading the program using JT-LINK's SW method, what are the requirements for the high and low levels of the BOOT0 and BOOT1 pins?...

High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
No matter which processor you are learning, the first thing you need to understand is the registers and working mode of the processor.
ARM has 37 registers, including 31 general registers and ...[Details]
The Mobile Industry Processor Interface (MIPI) Alliance is an organization responsible for promoting the standardization of software and hardware in mobile devices. It has released the D-PHY specif...[Details]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
When choosing a laptop battery, you should consider several factors, such as power, appearance, and quality.
Regarding power, we often see that a manufacturer uses values such as the number ...[Details]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
LED guardrail lights use fluorescent tubes or LEDs as light sources and continuous guardrails as carriers to form an approximately linear guardrail light strip. This article mainly introduces...[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]
