Determine device type1,Split View Controller(Uisplitviewcontroller) in the iphone application, the navigation controller is used to enter the next layer of interface from the previous interface. But the ipad screen is large and usually uses Splitviewcontroller for navigation (this is the ipad-specific view controller). On the horizontal screen, a navigation list is displayed on the left, and the corresponding details are displayed on the right.In the
Apply the configuration device to development and apply the configuration device To run an application on a device, First, set the device to allow it to run non-Google Play Store applications: For devices of Android 4.1 or earlier versions, select "Settings"> "application items" and select "Unknown Source.

Popular Science:UDID is a 40-string sequence of substrings and numbers that distinguishes each unique iOS device, including IPhones, IPads, and IPod touches As Apple gets more and more strict in the program to get Udid, the private API has not got the information such as the Udid,mac address, and then the use of keychain with the UUID and so on is implemented in disguise Due to the recent project requirements is the form of equipment licensing use of
I. Linux USB driver levels 1. devices, configurations, interfaces, and endpointsThe logical organization of a USB device consists of four layers: device, configuration, interface, and endpoint. A device usually has one or more configurations: Each USB device provides different levels of configuration information,
/*** Device_create-creates a device and registers it with sysfs* @ Class: pointer to the struct class that this device shoshould be registered* @ Parent: pointer to the parent struct device of this new device, if any* @ Devt: The dev_t for the char device to be added* @ Drvd
I. Overview Speaking of writing I2C drivers in Linux, there are currently two main methods: one is to treat I2C devices as a common character device, the other is to use the Linux I2C driver architecture. The two drivers are compared below. The advantages of the first method (corresponding to the disadvantages of the second method) include:● The idea is straightforward and you don't need to take the time to understand the complex I2C subsystem operati
How to use the platform device driver to write the driver:-------------------------------------------------------------------------1. Implement device orientation first:1) read the chip manual and obtain resources from the schematic diagram.2) construct a platform device structure and add platform Resources3) link our device
If you have multiple Android devices (including Android emulators) connected to your PC, you will need to use the Adb-s DeviceID shell when you enter the console. More trouble, this article has written a shell script file (need to be used under Linux or OS X, Windows needs to be newly written with bat or cmd).The basic idea is to use the ADB devices command to scan how many Android devices are connected to the PC, then intercept the device name from t
Recently encountered this problem of headache, baffled its solution, fools, cantilever thorn shares these things have done, finally see hope, so save, feel tidy share to everyone, hope to help.The initial understanding of cell phone resolution and web pixel is that it is twice times the difference.But what's puzzling is why we need 1.325 of this data, which is what it turns out to be:Give me a chestnut:The following is my excerpt and translation, want to know more text at the end of the link ha
As you know, on Windows IoT Core, if you use hardware such as a USB sound card and a camera with a microphone outdoors, you'll have multiple audio devices available. However, the system does not currently provide a direct UI to set the audio input or output device. After review, we can use the command line to change the default audio device, as follows.In the case of Raspberry Pi, I use a USB sound card, pl
This mainly covers the bindings between the coordinator and the terminal.This mechanism uses a button press or other similar action at the selected devices to bind within a specific timeout perio D. The End Device Bind Request Messages is collected at the coordinator within the timeout period and a resulting bindin G Table entry is created based on the agreement for Profile ID and cluster ID. The default end devic
Access Control of Device Files: exclusive devices, restrict access by only one user (Single User Access) at a time, block user access, and copy the device when the device is turned on. Exclusive devices are mainly used to allow drivers to maintain a atomic_t variable. This variable is initialized to 1, indicating that it is available. When open is enabled, it is
In the above-mentioned Drive series blog, we have learned about blocking and non-blocking, asynchronous notification, polling, memory and I/O port access, concurrency control and other knowledge, the key device driver is relatively simple, this chapter content can deepen our character device driver architecture, blocking and non-blocking, Interrupt timer and other relevant knowledge of the understanding. In

Share it with you for your reference. The details are as follows: Recently, due to work requirements, the above requirements need to be reported daily O M of hundreds of port usage [], altho
Prior to Linux3.1, board-level information is generally stored in the/arch/arm/mach-** directory for devices on a typical arm platform.The files for the device tree are stored in the/arch/arm/boot/dts/***.dts directoryThe purpose of the device tree introduction:Avoid the duplication of individual vendor code, accelerating the development of the Linux kernel BSP. Compiling a mirror can support multiple diffe
After a block device is mounted, you can view the file system information for the device via the DF or Mount command. However, sometimes it is necessary to judge without mounting the device, and the following method can be used:(1) View file system type command: File-sl/dev/testvg/lv0 Sample output:/dev/testvg/lv0:linux Rev 1.0 ext2 FileSystem data (large files)
