The purpose of this document is to present how to use the Timer for the generation of a PWM signal tunable in frequency and duty cycle. As an application example, this document is based on a basic “music” synthesizer through an external buzzer. Example code is also available in the it.
This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table.
Programming Windows with MFC isn t a book about C++ rather, it s a book about writing 32-bit Windows applications in C++ using MFC rather than the Windows API as the chief means of accessing the operating system s essential features and services.
This Handbook, published under the auspices of the Senior NATO
Logisticians’ Conference (SNLC), i s i ntended as a simple guide to logistics i n
NATO. It does not attempt to examine current i ssues or provide answers to the
problems that logisticians will face, but i t rather aims at i ntroducing them to some
of the basic principles, policies, concepts and organisations with which they will
work.
With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business. Every programmer must keep up with the latest tools and techniques. This updated version of Advanced Perl Programming from O Reilly gives you the essential knowledge of the modern Perl programmer. Whatever your current level of Perl expertise, this book will help you push your skills to the next level and become a more accomplished programmer.
There a t least five Request for Enhancement s (RFE) in the JavaSoft bug database related to Mouse Wheel support in Java. One of the RFE s BugID #4202656 has 281 votes from developers requesting Sun for a fix. Sun has finally agreed to support this feature in JDK 1.4 codenamed Merlin accroding to the BugID #4289845 in its bug database.
MTOOLS
version 2.0
Mtools is a public domain collection of programs to allow Unix systems
to read, write, and manipulate files on an MSDOS filesystem (typically a
diskette).
The following MSDOS commands are emulated:
Mtool MSDOS
name equivalent Description
----- ---- -----------
mattrib ATTRIB change MSDOS file attribute flags
mcd CD change MSDOS directory
mcopy COPY copy MSDOS files to/from Unix
mdel DEL/ERASE delete an MSDOS file
mdir DIR display an MSDOS directory
mformat FORMAT add MSDOS filesystem to a low-level format
mlabel LABEL make an MSDOS volume label.
mmd MD/MKDIR make an MSDOS subdirectory
mrd RD/RMDIR remove an MSDOS subdirectory
mread COPY low level read (copy) an MSDOS file to Unix
mren REN/RENAME rename an existing MSDOS file
mtype TYPE display contents of an MSDOS file
mwrite COPY low level write (copy) a Unix file to MSDOS
H.264/AVC, the result of the collaboration between the ISO/IEC
Moving Picture Experts Group and the ITU-T Video Coding
Experts Group, is the latest standard for video coding. The goals
of this standardization effort were enhanced compression efficiency,
network friendly video representation for interactive
(video telephony) and non-interactive applications (broadcast,
streaming, storage, video on demand). H.264/AVC provides
gains in compression efficiency of up to 50％ over a wide range
of bit rates and video resolutions compared to previous standards.
Compared to previous standards, the decoder complexity
is about four times that of MPEG-2 and two times that of
MPEG-4 Visual Simple Profile. This paper provides an overview
of the new tools, features and complexity of H.264/AVC.
