Preface This article and three others will analyze the IP Queue mechanism from user-mode applications to kernel-mode module programming. The titles of the three articles are: Analysis of the Linux Ker...
The circuit is shown in the figure. The front-stage transistors of the OCL circuit are: NPN-PBSS8110Y, PNP-PBSS9110Y. The models of the rear-stage transistors are: NPN-NSS1C301ET4G, PNP-NSS1C300ET4G. ...
I am working on the software side of a hardware project and now I have a problem that I would like to ask for a solution. A motherboard is connected to an MCU, which controls the voltage regulation or...
Notes on using an oscilloscope to test rippleMeasure using the AC coupling mode of the oscilloscopeBecause the oscilloscope head cover is easy to introduce noise, the probe head cover must be removed ...
The problem is this: About a month ago, I built a S3C2410 project on IAR6.1. I have two boards, one FS2410 board from Youlong and two UP-TECH2410 boards from Broadcom. There are two debuggers for that...
[color=#666666][font=arial, 宋体]I soldered a board myself. It was running fine, but suddenly the program configuration failed. I measured and found that the 1.2V would short-circuit as soon as it was p...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
