How to learn embedded systems? Embedded systems are a very practical subject. Those who want to learn embedded systems have read many books on ARM or LINUX, but still feel that they have not gotten st...
After booting with NK.bin image downloaded from USB of uboot, uboot is lost after restart! I have had similar problems before when using SKY2440 development board. Recently, a 2440 core board was burn...
Abstract: This paper introduces the characteristics of TinySwitch, a control device for low-power switching power supplies, and discusses that high-power switching power supplies occupy a large market...
Today I saw an article about the definition of pressure transmitter and sensor accuracy. The general meaning is: China and the United States are the same. Europe is just the opposite of us. At the end...
I have a s3c2440 development board, with an SD card slot, USB port and debug board (with serial and parallel ports), but no Ethernet card. But there is no manual, and the built-in bootloader cannot be...
Magnetic resonance imaging (MRI) systems can take high-resolution cross-sectional perspective images of the human body, providing very useful information for medical diagnosis. The radio frequency pro...[Details]
Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]
A biped robot joint constructed by pneumatic artificial muscles is introduced. The joint uses the flexible characteristics of pneumatic artificial muscles to effectively control the impact of the la...[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]
