After I connect my USB to the computer, I can see the device in the device manager, but I can't see the drive letter. I can't connect it using activesync either. I find that the "end of bus reset" int...
I remember talking about the method of using third-party software to download programs through the serial port. I used to think that using the JTAG port would be enough. Why bother? But now I want to ...
"Test-Driven Embedded C Development" introduces in depth how to apply test-driven development methods to embedded C development. The first part introduces two open source test frameworks and develops ...
I am using a S3C2410 board, and use GPIO to control DATA, CLK and KEY. When writing data, the BC7281B clock signal is normal, but the data pin is always high level, and the handshake cannot be establi...
The difference in the definitions of EMI, EMS and EMC: EMI stands for Electromagnetic Interference, which refers to the electromagnetic waves generated by electronic equipment during its own operation...
The radio frequency identification (RFID) market is experiencing strong growth, with sales reaching $1.7 billion in 2004 and expected to reach $5.9 billion in 2008. This surge in demand is driven b...[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]
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]

At present, a hot spot for the research and development of hearing aids abroad is concentrated in China. To be more precise, it is based on the research of Chinese language and speech, and the deve...[Details]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[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]
This issue will briefly introduce the test related to spectrum - occupied bandwidth.
Definition: Occupied bandwidth refers to the bandwidth corresponding to 99% of the total transmitted power, cent...[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]
