The chip can work normally, but the 27M passive crystal oscillator has only one output pin to start oscillating, and the input pin is 0 level. My oscilloscope is 200M, so there should be no problem....
Recently I am doing an experiment of using MSP430F149 to drive DHT11 to collect temperature and humidity and then display it on LCD1602. However, after the hardware is connected, it always displays 00...
The TMDSDOCK28335 is a DIMM100 controlCARD based evaluation and development tool for the C2000 Delfino F2833x family of microcontroller products. The docking station provides power to the controlCARD ...
I used TINA to perform an open-loop simulation of the OPA2369. The simulation curve does not match the curve in the data sheet. Let's see what the problem is....
[p=26, null, left][color=#000][font=Arial]Due to the needs of the project, I need to change the environment variables of u-boot in the application in linux. I was entangled for a long time and didn't ...
I need to detect the CPU frequency, memory capacity and other hardware information on the PDA. I downloaded a Pocket PC Mark_ARM software and it requires a registration code....
Embedded systems are the replacement products of computer technology, communication technology, semiconductor technology, microelectronics technology, voice and image data transmission technology, and...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
The role of digital-to-analog converters
Real-world analog signals, such as temperature, pressure, sound, or images, are constantly being converted into digital form that is easier to store, p...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
Sensors have made inroads into automotive, medical, industrial and aerospace applications. But you may not see anything changing yet. Growing demands for safety, convenience, entertainment and efficie...[Details]
As the whole equipment is constantly miniaturized and power-saving, low-power-consumption low-dropout linear regulators (LDO) are becoming the mainstream of the linear regulator market for switching p...[Details]
Safety is the top priority in the production process, especially for dangerous operations. When the high-voltage line is shut down for maintenance, it is necessary to follow the regulations of powe...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[Details]
1 Introduction
In recent years, with the rapid growth of mobile phones and MP4 video players, it is estimated that the production of mobile phones this year will reach 1 billion units, and...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Today, various applications such as consumption, computers, industry and instruments urgently need compact and effective power solutions, while also meeting the requirements of efficiency, fast tra...[Details]
Industrial control
often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]
A financial analyst pointed out that the signal reception problems of Apple's 3G iPhone may be caused by some defective chips.
