Gpio is the most basic input and output channel of the ARM chip. In ads, operations are performed by a single-chip microcomputer and its registers are directly read and written. On the arm9-7 platform, the Windows CE system maps the real IP address of gpio (for example, the base IP address of gpio 2410 is 0x56000000) to the virtual IP address space (the gpio corresponds to 0xb1600000, by performing operatio

The driver is successfully appliedThe implementation of the real-time clock function of the CE platform's handheld gps machine can be used as a reference for implementing the RTC function based on other
The default Windows CE 5.0 interface is as follows:
To ensure that the product has its own characteristics, the standard interface of Windows CE 5.0 has been modified. The example is as follows (the content in the Start menu is not clear, but you should know that the content has been modified):

When developing Windows Embedded Ce (wince) and using Huawei 3G modem em 770w, we found that the driver was faulty and required delayed loading. Later I found a simple method to delay the loading of the driver.
Add the flags entry to the registry of the driver device. The value of this item is 4, indicating that the driver will not be loaded automatically.
Devflags_noload 0x00000004-Allows you to have the

Microsoft works closely with silicon vendors and independent hardware vendors to offer you an extensive list of board support packages (BSPs) supported on Windows Embedded ce. by covering a full range of the latest supported microprocessors and other hardware components, our goal is to help you find compa

At this point, the kernel needs to wait for data from the registry to continue booting the system.SixThe next loaded module is Device.exe. The function of this module is to load and manage the drivers for the installable devices in the system.SevenThe next module to be loaded is gwes.exe.

In the article "how to diagnose Windows CE application crash", I introduced how to use the crack address function of Remote Process explorer to locate the program crash address. However, it seems that many people do not know how to use this tool. This article details it.

I have been checking a problem on windows over the past few days. In fact, it has little to do with Windows Mobile and Windows Embedded ce, but I also wrote a blog to find the cause.

When developing network applications, it's always necessary to capture network traffic. windows CE has built-in sniffer tool, netlog for this purpose. it captures network traffics to a file that can be examined with Wireshark or network monitor.
To enable it, we need to select NDIS Packet Capturing DLL and NDIS user-mode I/O protocol driver in Visual Studio, as shown below.
Then, we can capture network

This article describes how to implement page navigation in Windows Phone 8.1.
The implementation of page navigation in Windows Phone 8 is certainly not unfamiliar, we use navigationservice to achieve. The specific wording is this:
Navigationservice.navigate (New Uri ("XAML Relative Path", Urikind.relativeorabsolute)
Navigationservice: used to process the navigation of Windows Phone pages

If you know something about Silverlight or WPF development when learning about Windows Phone 7 development, I believe the Navigation Framework must be yours.
. Therefore, when I was learning Windows Phone 7 Application Development, I felt that it would take some time to understand the underlying layer.
Principles.
First, the Application of
navigateuri of the music hyperlinkbutton.
In this way, you can start the program and navigate to the following three items according to the same operation,
Use C # code for navigation (using a very important class)
Step 3 is required to use an alias for navigation: Step 1 defines the ing rules in the app. XAML file, and step 2 initializes the defined resource in APP. XAML. CS.The secon
framework of the application to the resource file we wrote previously. It can be seen that a map indicating each page is assigned to urimapper, so that we can call it.
Call method:
First declare a hyperlinkbutton control and set navigateuri as the alias of the corresponding page. For example:
Name = "musicshyperlinkbutton" verticalignment = "TOP" width = "200" navigateuri = "musics"/>
In this way, the alias navigation of the page is realized.
TIPS: s
Almost all real applications do not have only one XAML page, so page navigation is particularly important. Page navigation involves not only page jumps, but also data transmission between pages and heavy loading of Back buttons. This section only provides simple page navigation, data transmission, and Back buttons for further writing.
1. Use XAML for page
