Release date: 20090410 Author: maxblog reposted Source: blog recommender of maxblog: Nian Xue The mobile online streaming media project in the previous stage has finally come to an end. The following is a summary and accumulation of development:1. online streaming media playing on mobile phones has many restrictions, including:1) The network speed of the mobile phone is limited. GPRS is generally about 5 kb/s, and edge is about 10 kb/s;2) The CPU frequency of mobile phones is

during the compilation period. This will not cause errors and make the program more portable. 4. sizeof of basic data type The basic data types here refer to simple built-in data types such as short, Int, long, float, and double. Because they are all related to the system, the values may be different in different systems. This must attract our attention, and try not to cause trouble for porting our programs in this respect. Generally, in a 32-bit compiling environment, the value of sizeof (INT)
do_bootm_linux; # Else Extern boot_ OS _fcn do_bootm_linux; # Endif Copy code The precompiled macro here illustrates that the do_bootm_linux () function of the CPU that is not in the PPC architecture is not implemented in this file (extern ). It is conceivable that the implementation of this function should be related to the architecture. Specifically, the implementation of the ARM architecture is in the lib_arm/armlinux. c file. We can see that
If you are new to embedded development, there may be too many available bootloader, distribution, file systems, and guis. However, these rich options are actually a gift that allows you to adjust the development or user environment to fully meet your needs. An overview of Linux embedded development will help you understand all these options. Linux is developing steadily in the field of embedded development. Because Linux uses GPL (see references later in this article ), therefore, anyone who is
The previous Mac OS X Leopard: configuration of Apache, PHP, SQLite, MySQL, and phpMyAdmin (1) describes the Apache and PHP settings built in leopard, here we will introduce the installation and configuration of MySQL and phpMyAdmin, because these are not the leopard built-in software (the leopard server has built-in MySQL), so there will be some problems, here I will provide a solution to the main problems. Iii. MySQLIf you are running the OS x Leopard server, MySQL is installed by default in

. sizeof pointer variableIf you have learned the data structure, you should know that the pointer is a very important concept, which records the address of another object. Since the address is stored, it is equal to the width of the computer's internal address bus. Therefore, in a 32-bit computer, the return value of a pointer variable must be 4 (note that the result is in bytes), which can be predicted, in the future 64-bit system, the sizeof result of the pointer variable is 8.

Development (Visual Studio 2005 Express is not currently supported ). When Visual Studio 2005 is installed, you only need to select the "smart device programmable technology" option in Figure 1, after installation, you can use Visual C # To develop a smart device Program Hosting code. 2. After Visual Studio 2005 is installed, We need to install the ActiveSync software so that we can continue to complete the SDK installation for a specific platform. We hope you will pay attention to this order.

ArticleDirectory Preparing the host server Qemu is well-known as a free replacement for VMware, allowing users to run a PC within a PC. what isn't so well known about qemu is that, in addition to emulating x86 ubuntures, it can emulate amd64, iSCSI, MIPS, PPC and arm CPUs. In the case of the ARM architecture, qemu provides a convenient, if slow, environment in which development can be done for embedded systems. This article describe

In the first two weeks, I joined a workflow demonstration project for the customer. The goal of the project is to demonstrate how to build a workflow system that can reflect the advantages of mobile devices in a short time. The SharePoint Portal Server 2003 is used as the basic Web component of the entire system. One process uses infopath as the form input terminal: The workflow engine uses K2, K2 can be well integrated with SharePoint/infopath, and has excellent scalability. You can direc
