This project is created using the Keil ARM CA Compiler.
The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1
This ARM Example may be debugged using onl ...
书籍 Radio Frequency Identification and Sensors
There is an unprecedented enthusiasm for radio frequency
identification (RFID) technologies today. RFID is based on the
exchange of information carried by electromagnetic waves between a
label, or tag, and a reader. This technology is currently in full
economic expansion, which has manifested itself ...
书籍 Applied+Electromagnetism+and+Materials
This book describes the applications of the fundamental interactions of
electromagnetic waves and materials as described in the preceding volume, “Basic
Electromagnetism and Materials”. It is addressed to students studying masters or
doctorate courses in electronics, electromagnetism, applied phys ...
书籍 Communications+Receivers
The capability of radio waves to provide almost instantaneous distant communications
without interconnecting wires was a major factor in the explosive growth of communica-
tions during the 20th century. With the dawn of the 21st century, the future for communi-
cations systems seems limitless. The i ...

This book provides the reader with the basics in radio engineering,
the techniques needed to generate, control, detect, and use radio waves. The
text approaches the relevant problems both from the electromagnetic theory
based on Maxwell抯 equations and from the circuit theory based on Kirchoff
and O ...

Linux/uClinux/Unix编程 DDA使用教程
DDSCAT 7.3 is a freely available open-source Fortran-90 software package applying the “discrete
dipole approximation” (DDA) to calculate scattering and absorption of electromagnetic waves by targets
with arbitrary geometries and complex refractive index. The targets may be isolated entities (e.g., ...
