Preface: Recently, there have been many discussions on KiCad software on the forum. I looked it up online and found the following article, which is quite detailed. Netizens who are interested in KiCad...
The circuit board was developed by someone else in the early days, but now I can't find the person who developed it. I want to replace the passive crystal oscillator with an active crystal oscillator ...
Hello everyone! I am using the MSP430F5529 development board and burning the " singlePWM project " provided by TI . The code uses the P2.0 port and I read the board schematic. I want to change the PWM...
Dear embedded system veterans, I have only played with cortex M-level microcontrollers such as STM32 and TM4. I don't know Linux and have never touched cortex A-level processors. Recently, I want to p...

The first step in measuring analog signals with a digital oscilloscope is to use an ADC (analog-to-digital c...
TI's battery experts have decades of experience. Our battery scientists work to deliver cutting-edge solutions for new battery chemistriestechnologies, from charging, gauging, monitoring to protection...
When developing MCUs, some simple digital logic circuits are sometimes needed. The LPC804 and LPC55XX series integrate PLU (Programmable Logic Unit), a programmable logic unit, which can create small...[Details]
Wireless network coverage optimization is very important for improving the perception of existing network users. Good wireless network coverage is the premise for ensuring the quality and indicator...[Details]
1 Introduction
In the ARM+FPGA system structure, the simplest way to achieve communication between the ARM-based embedded processor and the FPGA is through the asynchronous serial interface EIARS2...[Details]
3.3.17 R8:
The role of R8 is to protect Q1 and prevent Q1 from being in a floating state.
3.3.18 R7 (Rs resistor):
The maximum voltage of 3843 Pin3 is 1V. The size of R7 must be coordinated wit...[Details]
We all know that the power device segment products mainly include MOSFETs, power modules, rectifier bridges, IGBTs, etc. According to Yole Development statistics and forecasts, the power device marke...[Details]
Apple today pushed the watchOS 8.3 Developer Preview Beta2 update (internal version number: 19S5036d) to Apple Watch users. This update was released one week after the last one. watchOS 8.3...[Details]

Characteristics and models of neutral grounding resistors Neutral point grounding resistor cabinet is mainly used for connecting the neutral point of main transformer and grounding network in urb...[Details]
The most fundamental human desire is to evolve, to make things better, faster, bigger. We see the same tendency repeated over and over again in the semiconductor industry. Not bigger, of course, but ...[Details]
The distance between the probe's GND and signal detection points is too large. Figure 1: Quantization error of the oscilloscope DC. The oscilloscope has quantization error. The ADC of the real-time...[Details]
1 Introduction In an embedded system that adopts the foreground and background system software design mode, the main program is an infinite loop, a single task is executed sequentially, and async...[Details]
How to use math function waveforms Use the math function control to select a math function: • Addition. • Subtraction. • Multiplication. • FFT (Fast Fourier Transform). Math results can be measured u...[Details]
First of all, it should be made clear that whether the "resistance" state in the circuit is high or low, it is relative to a certain reference point. Once this is clear, the working status of the I/O...[Details]
With the development of science and technology, there are more and more types of electronic products, and the demand for electronic components is also increasing. Capacitors are important electroni...[Details]
Have you heard of Moravec's paradox? The paradox states that for artificial intelligence (AI) systems, high-level reasoning requires very little computing power, while achieving the perceptual-moto...[Details]
