Setting up the test environment for S3C6410 Development BoardThe Development Board is the main hardware device for developing and learning embedded technologies, although Linux drivers can be developed on a PC and then recompiled into an ARM-architected Linux driver module. But in the end it's going to be tested on the Development Board.This book mainly introduces the s3c6410 Development Board and the OK641

1. OverviewWith the rapid display of mobile smart devices, battery life in a very large case induced the choice of mass consumers, Android system Power Management is reasonable or not directly affect the battery life, and battery system as part of it, Mainly used for monitoring the battery status (battery level, battery status and battery temperature, etc.). The following is a detailed analysis of Android's battery system architecture.2.

Android app power consumption statistics has always been a headache, manual statistics time is too long, automated statistics is not very accurate (the implementation of automation code needs to connect via USB, and USB will charge, which results in statistical data is not allowed). Later from the predecessor learned that you can use the ADB connect to achieve wi

So-called1/0memory is through various interfaces (PCI,USB, Bluetooth, Ethernet port, etc.) connected to the host (PC, the hardware of the mobile phone (network card, sound card, camera, etc.) in the host memory

Are you still using a USB cable to connect your mobile phone to access sdcard ?, You are out. This article will tell you that if you connect your laptop to your mobile phone through wifi and quickly access sdcard, you certainly do not need a wireless router. Prerequisites The laptop system is windows 7, and the wireless network card is normal and the driver is normal.

chapterThe first driver counts the number of words. In addition to introducing a lot of theoretical knowledge of Android porting and Linux Driver Development, this book allows you to enter Another world of Linux. There is no essential difference between Linux and Linux APIs .Knowledge uses APIs in different ways. The steps of writing a Linux

Android is essentially a Linux kernel based system, which means Android is a Linux operating system. But most of the time it will run on arm-architecture devices, such as Android phones, tablets, and so on. Android drives are actually Linux drivers, but here's Android Deep E

Sixth Chapter First Linux driver: Count the numbers of wordsThe Word_count driver for counting the number of words is the first complete Linux drive implemented in this book. Although the functionality of the Word_count drive is not complex, it is enough to allow developers who have never been in touch with Linux drivers to understand the complete development of Linux drivers. This chapter not only introdu

The Development Board is the main hardware device for developing and learning embedded technologies, although Linux drivers can be developed on a PC and then recompiled into an ARM-architected Linux driver module. But in the end it's going to be tested on the Development Board. This is mainly because the ARM architecture of the board can be based on the X86 architecture of the
