I have been using QT for a while. I will summarize some of my recent minor problems and share them with my new friends. 1. the united function of the qpainterpath class can combine multiple paths to connect their edges. In qgraphicitem, a shape
The interrupt controller is also one of the many peripherals of the CPU. The difference is that it receives the input from other peripheral interrupt pins and sends the interrupt signal to the CPU. It is a block diagram of the interrupt controller

Relationship between processes and threads:
(1) A thread can belong to only one process, and a process can have multiple threads, but at least one thread.
(2) resources are allocated to the process. All threads of the same process share
(1) the I/O interface is an external device of the XScale processor. For general single-chip microcomputer, you can directly operate the hardware, that is, access the hardware by directly reading/writing the I/O port. for the wicne operating system,
I/O operations on peripherals are actually the registers for reading and writing peripherals. The x86 or ARM processor we usually use determines on the hardware that the physical address cannot be directly accessed after the wince system
Someone may be as anxious as I am and want to know how to write a specific driver as soon as possible. Here, we assume you have a good understanding of the driver, let us know how to get on the road quickly. Of course, if you have enough time, I
Yesterday, I saw a very interesting picture on the bib. It was a digital inversion image, so I was playing it in Java.
The implementation code is as follows:
Public class meili1 { Long sum (int n){If (n = 1)Return 1;ElseReturn sum (n-1) * 10 +
After modifying the driver that comes with wince, how can I compile it? How to compile a self-developed driver?
1. It can be divided into ide mode and command line mode. IDE compilation is simple. Take pb5.0 as an example. Open the custom kernel
6410 in the wince6 system under the platform, it is found that the system is disabled by using the setsystempowerstate API function in the application layer.
The application layer is called as follows:

1. In the smdkv210 \ SRC \ oal \ oallib \ ksarm. h header file, we can see the wince interrupt definition.
The START Number of the device interruption, that is, the Base Value of the device interruption ID predefined by wince.
Sysintr_devices equ
From the previous introduction, we learned about the bare metal Interrupt Processing Process and the Wince-driven Interrupt Processing. But how does wince handle the interrupt at the underlying layer? Here we will introduce the oal layer interrupt
Generally, we need localalloc in the driver to reserve a bucket, and then map the I/O port to the address using localcopy. Then we can access the reserved address.The handling of interruptions varies with various devices. If it is a built-in device (
When your android API is changed from version 2.1 to Version 2.2:

This macro is used to register the information of this class. When we want to obtain the information
Qtimer or qbasictimerqtimer is mainly designed for timing, and qtimer is easy to use. For example, suppose the constructor has the following code: qtimer * timer = new qtimer (this); timer-> setinterval (1000); // 1000 ms = 1 s Connect (timer,
