Through this chapter of learning, I learned some basic knowledge, as well as the use of program control LED light process.1,android System ArchitectureThe Android system is divided into 4 tiers, namely the Linux kernel, c/S code base, Android SDK API, application. The Linux kernel is responsible for the most basic functions, such as memory management, security, p

whether the current system supports USB to serial portStep Two: Install MinicomStep Three: Configure MinicomFourth step: Detect MinicomBefore burning the Android system, you need to use Eboot to erase the Nandflash, as follows:The first step: getting Ready for workStep Two: Enter the Eboot stateStep Three: Erase NandflashThe steps to burn Android are as follows:The first step: getting Ready for workStep tw

Wifi is ready to work, and most of the features required in Android wifisetting are also implemented. However, there are two other problems to record here: 1. softap unavailable 2. There is a probability that WPS will fail. For softap, when WiFi tethering is selected in setting, softapcontroller sends a private command to the driver. However, before sending a private command, the siocgiwpriv command is sent

important to note that there are two JRE, one under the JDK and one installed separately, both of which can be used, and the former is used here. When you set a path path, you can reference the previously setJava_home variable, the reference method is to add a% (for example:%java_home%/bin;%java_home%jre/bin) before and after the Java_home variable name. Select the system variable, advanced system settings, properties-----------------------------That is%java_home%/bin;%java_home%jre/bin. (4) te

Delphi sometimes cannot connect to debug some phones, solutions:1. Install Google USB Driver2. Check the phone or tablet USB vid,pid via Device Manager3. Modify the Android_winusb.inf on your computer to add the vid,pid found in the 2nd step to the INF.For example:; Samsung Galaxy S3%singleadbinterface% = usb_install, usb\vid_04e8pid_6860%compositeadbinterface% = USB_Install, Usb\vid_04e8pid_6860mi_03For details, please see:http://delphi.org/2014/01/custom-a
