BKJIA Editor's note: A blue ray of the sky, RIM's BlackBerry is a little overwhelmed by the aggressive trend of iOS and Android. According to BGR, the BlackBerry QNX system program is developed with Dalvik! Dalvik is a Java Virtual Machine for Android, and Android applications are developed using Dalvik!

The embedding process of QNX is generally:
Build buildfile-> compile buildfile to generate the system image file-> Start the target system-> Design the embedded system software.
The key is to build buildfile [19]. Generally, an embedded system requires an operating system image file that can be started ). For a QNX-based embedded application system, the embedded system is customized based on the selected C
with the help of a third-party mobile device management (MDM) tool in a few months.
Recall that in July March this year, RIM began to promote the market for its unofficially released BlackBerry PlayBook tablet, and said that its QNX operating system would be able to smoothly run Android applications. It turns out that these scams once again played with our feelings. In the end, RIM used a mechanism similar
QNX is a UNIX-like real-time operating system that complies with POSIX specifications and has good portability.
Writing any driver has the same problem: how the application interacts with the driver. In fact, this problem is very simple. QNX has a lot of information to illustrate this point.
This problem occurs when the client calls FD = open ("Dev/mydevice", o_rdwr) to open the device mydevice and expects
Smart appliances are rapidly developing. Many enterprises in China are actively deploying Smart appliances. Haier is the most typical. As a leader in the field of household appliances, Haier has made great efforts in the field of Smart Home Appliances in recent years. According to recent news, Haier may announce the development of high-end smart refrigerators for QNX systems at the IFA exhibition, this has aroused strong repercussions in the industry.
You want the process that sends the data to run in the background, but this problem occurs when you start the process.In general, this problem may be related to the following reasons:"[1] + Stopped (TTY input)" means that the program tries to read from the control terminal, but is stopped by the sigttin signal because it is running in the background:The man signal has the following output:Sigttin Stop process Background read attempted from Control terminalThe following program demonstrates this

QNX is a real-time operating system developed by QNX software system Ltd. (qssl) in Canada based on micro-kernel and full address space protection, real-time, distributed, multi-task, and modular cropping. It complies with POSIX standards and is one of the few real-time operating systems that support graphic user interfaces. The QNX kernel only provides the most
program.So how do you write an interrupt in QNX? QNX offers two ways to connect interrupts:int interruptattachevent (int intr, const struct sigevent *event, unsigned flags);int Interruptattach (int intr, const struct sigevent * (*handler) (void *arg, int id), const void *area, int size, Unsigne D flags);where int intr represents the interrupt vector number, it is written in the data sheet when the pic is i

As we all know, QNX is a micro-core operating system that relies on interprocess communication to achieve the entire system function. So specifically to write a program, exactly how this communication is done? This chapter is specific to the bottom of the message delivery API. Message passing is done through the kernel, so the so-called API, which is actually the lowest-level kernel call. It should be noted that when you really write programs on
The difference between QNX and linux-general Linux technology-Linux technology and application information. The following is a detailed description. I am now studying the QNX operating system. Although it is QNX, it actually has a lot to do with linux. I hope to find some like-minded friends here and learn QNX together

I have been idle for a while recently, so I learned how to develop BlackBerry. Of course, the first step of development is to build a development environment. Google has a few tutorials, but they are very old, probably because there are few BlackBerry developers in China. The advantage of Blackberry is its well-known security, so there are a group of loyal fans.
network connection and transmission mode
The BlackBerry Solution acts as a bridge between the wired and mobile networks, the public network (the Internet) and the Internal network (intranet), leading to a wide variety of internet connections and data transmission patterns involved in BlackBerry.
From an application perspective, the following factors need to be considered in selecting the data transfer mode
1. Create a folder in windows, such as D:/share. Set this folder as a shared folder.
2. view the Windows IP address (not the IP address of VMware network adapter vmnet1/8, windowsip address), such as 192.168.1.2
3. view the computer name of a Windows system, that is, the complete computer name in the computer system properties, such as the PC-201102090128
4. Run FS-CIFS-L/PC-201102090128: 192.168.1.2:/share/tmp in QNX System
