Description

From Free-Engineering-book site describe that Welcome to the world of JavaScript, invented in 1995 by Brendan Eich it is still the most commonly used scripting language around today. It is high level, interpreted, cross platform and an open source programming language. In this tutorial series, we are going to learn JavaScript with practical examples. Before we dive in, let’s go over some of the basics.

JavaScript is an OOP scripting language which mainly used in Web programming. It is responsible for making web pages interactive; in simple words “it tells web page what to perform”. Like HTML defines the contents of the web page and CSS defines the layout, JavaScript make that web page work properly. JavaScript programs are the set of instructions which are executed in the order they are written so while coding, we should take care of the logical sequence.

Description

This is one circuit schematic of 100W Audio Amplifier using TDA7294 IC. According Circuitstoday site describe that TDA7294 is an integrated, monolithic, Class AB audio amplifier designed specifically for Hi-Fi applications. The IC has a DMOS output stage and can deliver 100W RMS into an 8Ohm speaker at +/-38V dual supply. The TDA7294 has low noise, low distortion, good ripple rejection and can be operated from a wide range of supply voltages. The IC has built in short circuit protection and thermal shutdown circuitries. The IC is available in multiwatt 15V and multiwatt 15H packages.

In the circuit TDA7294 is configured to provide 100W output power into an 8Ohm loudspeaker at +/- 38V supply. C8 is the input coupling capacitor and the input is applied to the non-inverting input (Pin3) of the IC. C3 and C9 are power supply filter capacitors while C10 and C4 are bypass capacitors. C2 is the bootstrap capacitor. RC network comprising of R1 and C1 improves the high frequency stability of the amplifier and also prevents oscillations. R2 and C6 sets the mute time constant while R3 and C5 sets the standby time constant. S1 and the mute switch and S2 are the standby switch. R5 is the input resistance and the amplifiers input impedance has a direct relationship to its value. R4 and R6 is used for setting type closed loop gain and with the used value, gain is 30dB. C2 is a feedback capacitor and it also provides DC decoupling.

  2. LED
  3. Capacitors
  4. LM317T IC
  5. Variable resistor
Description

This is circuit of Mobile Phone Battery Emulator using LM317T. Depending Electroschematics site which also published this circuit describe that the typical target voltage of the Li-ion battery is 4.2 V (note that the target voltage is not the same as the nominal voltage, as it is 3.7 V typical). An adjustable voltage regulator is designed as the mobile phone battery emulator. The circuit based on the popular three-pin adjustable voltage regulator LM317T (IC1) receives external dc input of 9 V/2 A through input connector J1. The output voltage available at connector J2 can be adjusted from just below 3 V to just above 4 V with the help of the 500-Ω multi-turn preset pot (RP1). Although most devices powered by Nokia batteries appear to work well at about 4.2 V, a little bit of experimentation with the values of resistors R2-R3-RP1 may be necessary. As stated earlier, the 82-kΩ resistor (R4) is essential to fooling the device into thinking that a real battery is attached at its battery connector.

Embedded Systems: Introduction to Arm® Cortex™-M Microcontrollers, Fifth Edition (Volume 1) 5th Edition by Jonathan W Valvano - Free Download E-book

Robometricschool. - Do you need Arm and Microcontroller book with many focused learning in this time? We suggest you to read a book with the title Embedded Systems: Introduction to Arm® Cortex™-M Microcontrollers, Fifth Edition (Volume 1) 5th Edition that authored by Jonathan W Valvano.



In this time, we will give you global description about this book, and then the last we will give you the link to take free download e-book of Embedded Systems: Introduction to Arm® Cortex™-M Microcontrollers, Fifth Edition (Volume 1) 5th Edition by Jonathan W Valvano from external server easily.

Description

From Amazon.com describe that Embedded Systems: Introduction to Arm® Cortex™-M Microcontrollers book is  self-published and is printed on demand. The original ISBN was generated in 2012, but if you purchase the book new from CreateSpace or Amazon you will get the new version, which was uploaded June 29, 2015. This book, now in its fifth edition, is the first in a series of three books that teach the fundamentals of embedded systems as applied to the ARM® Cortex™-M family of microcontrollers. 

This fifth edition focuses on the LaunchPads based on both the TM4C123 and TM4C1294 microcontrollers. 

This first volume is an introduction to computers and interfacing focusing on assembly language and C programming. 

The second volume, Embedded Systems: Real-Time Interfacing to ARM Cortex-M Microcontrollers, focuses on hardware/software interfacing and the design of embedded systems. 

The third volume, Embedded Systems: Real-Time Operating Systems for ARM Cortex-M Microcontrollers, is an advanced book focusing on operating systems, high-speed interfacing, control systems, and robotics. 

The third volume could also be used for professionals wishing to design or deploy a real-time operating system onto an ARM platform. This first book is an introductory book that could be used at the college level with little or no prerequisites. An embedded system is a system that performs a specific task and has a computer embedded inside. A system is comprised of components and interfaces connected together for a common purpose. 

This book is an introduction to embedded systems. Specific topics include microcontrollers, fixed-point numbers, the design of software in assembly language and C, elementary data structures, programming input/output including interrupts, analog to digital conversion, digital to analog conversion. This book employs many approaches to learning. It will not include an exhaustive recapitulation of the information in data sheets. 

First, it begins with basic fundamentals, which allows the reader to solve new problems with new technology. Second, the book presents many detailed design examples. These examples illustrate the process of design. There are multiple structural components that assist learning. Checkpoints, with answers in the back, are short easy to answer questions providing immediate feedback while reading. Simple homework, with answers to the odd questions on the web, provides more detailed learning opportunities. 

The book includes an index and a glossary so that information can be searched. The most important learning experiences in a class like this are of course the laboratories. Each chapter has suggested lab assignments. More detailed lab descriptions are available on the web. Specifically for this volume, look at the lab assignments for EE319K. 

For Volume 2 refer to the EE445L labs, and for Volume 3, look at the lab assignments for EE445M/EE380L.6. There is a web site accompanying this book http://users.ece.utexas.edu/~valvano/arm. Posted here are Keil™ uVision® and Texas Instruments Code Composer Studio™ projects for each of the example programs in the book. 

You will also find data sheets and Excel spreadsheets relevant to the material in this book. The book will cover embedded systems for ARM® Cortex™-M microcontrollers with specific details on the LM3S1968, TM4C123, and TM4C1294. Most of the topics can be run on any of these microcontrollers. In these books the terms LM3S LM4F and TM4C will refer to families of microcontrollers from Texas Instruments. Although the example designed are specific for the TM4C123, it will be possible to use these books for other ARM derivatives.
