技术资料 基于ARM单片机的汽车发动机故障诊断系统的研究
在研究了常见的汽车诊断系统及车载诊断装置(OBD)结构和工作原理的基础上,设计了基于STM32F103单片机芯片作为主控电路的随车式汽车发动机故障诊断系统。通过电源电路、外部调试电路、CAN总线通信电路和K线通信电路的设计,实现了通过OBD-Ⅱ诊断接口与汽车ECU进行通信。设计了硬件电路PCB并进行试制,编制了上位机程序将常用诊 ...
单片机编程 SJA1000 Stand-alone CAN contro
The Controller Area Network (CAN) is a serial, asynchronous, multi-master communication protocol forconnecting electronic control modules, sensors and actuators in automotive and industrial applications.With the SJA1000, Philips Semiconductors provides a stand-alone CAN controller which is more than ...
教程资料 通信的数学理论
The fundamental problem of communication is that of reproducing at one point either exactly or approximately a message selected at another point. Frequently the messages have meaning; that is they refer to or are correlated according to some system with certain physical or conceptual entities.

书籍 Cognitive+Radio,+Software+Defined+Radio
Today’s wireless services have come a long way since the roll out of the
conventional voice-centric cellular systems. The demand for wireless access
in voice and high rate data multi-media applications has been increasing.
New generation wireless communication systems are aimed at accommodating
thi ...
书籍 Globalization+of+Mobile
This book is the outcome of the panel discussions held on the special event honor-
ing first 50 PhD students of Prof. Ramjee Prasad. Several of his PhD students are
today worldwide telecommunication leaders themselves. Over 60 post-docs, PhDs,
colleagues and the scientific staff were present at the ...
书籍 Propagation Channel Characterization
The investigation of the propagation channel is becoming more and more important in mod-
ern wireless communication. The demand for spectral efficiency motivates exploitation of
all channels that can possibly be used for communications. Nowadays, a common trend for
designing physical layer algorithm ...
书籍 Reconfigurable+Mobile+Radio+Systems
Digital mobile wireless communication and the Internet have undergone a
fantastic growth in the last few years and, despite originating from two different
worlds, they are converging. This convergence corresponds to the evolution of
mobile systems towards the highest broadband data transmissions (GS ...
书籍 Ultra Wideband Signals and Systems
In the two years since this book was first published, ultra wideband (UWB) has
advanced and consolidated as a technology, and many more people are aware of the
possibilities for this exciting technology. We too have expanded and consolidated
materials in this second edition in the hope that ‘Ultra ...
单片机编程 PCA9547 8 channel I2C bus mult
The PCA9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Only oneSCx/SDx channel can be selected at a time, determined by the contents of theprogrammable control register. The device powers up w ...
