The serial port of the 559 board I have cannot receive (I plan to transplant the ISD function). I suspect it is a problem with the board. A few days ago, I posted a thread "Urgent need a program for C...
Due to design requirements, I studied the CAN of F28m35 and conducted relevant tests. There is no problem in sending and receiving data in the internal loopback test mode, but in the external test, th...
PB7 is the 89th pin of LM3S9B96. The data sheet says that it can be used as GPIO or NMI. However, after I configured it as GPIO input and gave it a high level, the voltage collected in the program was...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
With the promotion of the construction of intelligent communities in the country, anti-theft systems have become essential equipment for intelligent communities. Especially in recent years, the urg...[Details]

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
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 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]
In order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[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]
introduction
For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[Details]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[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]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
Continuity test
A variety of devices need to be checked for continuity, including cable assemblies, printed circuit boards, and connectors to ensure that these components have the expected contin...[Details]
