I have two .msi installation packages, A.msi and B.msi. Both can be installed correctly in Windows XP. But in XPE, one can be installed, and the other fails with the error "This installation package c...
[font=宋体][size=3] The stm32f769 development board integrates a WiFi interface, which lays the foundation for the development of IOT applications. With the help of the onboard LCD display and some API ...
I have been working on wind power pendulum for 15 years. When I input y-axis sine wave and x-axis is 0, the output amplitude cannot keep up with the input. I don't know what the problem is. I beg all ...
I would like to ask, how do I send a byte of data to the host in SPI slave mode? It seems from the STM32 manual that MOSI and MISO are sampled on the same clock edge, but there is only one SPI data re...
I am currently working on a laser pre-circuit, a transimpedance amplifier, referring to the specification sheet of opa847, and the chip I use is also opa847. Because the circuit is relatively simple, ...
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[Details]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]

Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
TMC428 is a stepper motor motion controller from TRINAMIC. It can reduce the workload of motor control software design and development costs. The 3-axis stepper motor drive control system based on ...[Details]
Stepper motors, also called steppers, use the principles of electromagnetism to convert electrical energy into mechanical energy and have been used since the 1920s. With the increasing popularity o...[Details]
1 Causes of problems with electric vehicle batteries
1.1 Caused by the battery itself
Why do we say that? In the previous issue, we learned about the working princi...[Details]
Lithium iron phosphate batteries are used as lithium-ion secondary batteries. Their main application is now in power batteries, which have great advantages over NI-H and Ni-Cd batteries.
