CBC下寫的串口編程，API函數實例
I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.

Introduction to GPS ToolKit Pro 1.0
GPS ToolKit Pro is an ActiveX object that makes it easy to add GPS support to any Visual Basic, Visual C++, Delphi, Excel, or scripting project that supports ActiveX controls. GPS data (including lat/lon, speed, course, altitude, and dozens of other datasets) can be accessed through GPS ToolKit s properties, and GPS ToolKit s multithreaded event-based architecture notifies your application when data has been updated, saving you from having to write messy polling routines.

These routines transmit and receive serial data using two general
* I/O pins, in 8 bit, No parity, 1 stop bit format. They are useful
* for performing serial I/O on 8051 derivatives not having an
* internal UART, or for implementing a second serial channel.

Ever wanted to just type tail -f error_log on Windows?Envious of your Unix friends who can track changes to a file, in real time, as they happen?
Well, now with the Objektiv Tail for Win32, you ll be happily monitoring your log files like you ve never done before.
What s even better, you can track several files all at the same time with the patented "Multiple Document Interface"TM technology, with each file having its own, fabulous window.

A six people s rushing replies an implement, use some s switches in toggle switch K0 ~ K5 is that ON accomplishes when rushing to reply button , nobody rush to answer, 6 numerical code circulation takes turns at demonstrating 1 ~ 6 (horse races) , who rushes to reply the numerical code stops having a ride on a horse , first, whose serial number, has simultaneous light of 6 numerical codes again afterwards the key presses down. System denies responding to, until this place is OFF batch , the wheel restoring 1 ~ 6 horse races starting time as soon as rushes to answer.

A general technique for the recovery of signi cant
image features is presented. The technique is based on
the mean shift algorithm, a simple nonparametric pro-
cedure for estimating density gradients. Drawbacks of
the current methods (including robust clustering) are
avoided. Feature space of any nature can be processed,
and as an example, color image segmentation is dis-
cussed. The segmentation is completely autonomous,
only its class is chosen by the user. Thus, the same
program can produce a high quality edge image, or pro-
vide, by extracting all the signi cant colors, a prepro-
cessor for content-based query systems. A 512 512
color image is analyzed in less than 10 seconds on a
standard workstation. Gray level images are handled
as color images having only the lightness coordinate

Verilog HDL: Magnitude
For a vector (a,b), the magnitude representation is the following:
A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

Jitter is extremely important in systems using PLL-based
clock drivers. The effects of jitter range from not having any
effect on system operation to rendering the system completely
non-functional. This application note provides the reader
with a clear understanding of jitter in high-speed systems. It
introduces the reader to various kinds of jitter in high-speed
systems, their causes and their effects, and methods of reducing
jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.

The second volume in the Write Great Code series supplies the critical information that today s computer science students don t often get from college and university courses: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level, teaches software engineers how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, a software engineer can make an informed choice concerning the use of those high-level structures to help the compiler produce far better machine code--all without having to give up the productivity and portability benefits of using a high-level language
