July, 2010 Tahmina Begum v ABSTRACT This thesis mainly focuses on the controlling of home appliances remotely and providing security when the user is away from the place. The system is SMS based and uses wireless technology to revolutionize the standards of living. This system provides ideal solution to the problems faced by home owners in daily life. The system is wireless therefore more adaptable and cost-effective. The home appliances control system provides control on automation of various home appliances using SMS. The system is capable enough to receive the instruction from user via SMS by a cell phone to change the condition of the home appliance according to the user’s needs and requirements. The system uses GSM technology thus providing ubiquitous access to the system for automated appliance control. The whole system is comprised of two components; one is hardware includes, PIC Microcontroller, GSM Module, Cell phone, power supply, sensors and relays. Other part is to develop master software based on PICBasic Pro and EPIC WIN software which is capable of remote controlling and monitoring appliances and devices via the SMS. The Prototype developed in the premises of Dhaka University of Engineering and Technology (DUET) shows the ability to receive and transmit back the SMS to communicate with the user and automate the home appliances. Results proved that home appliances control is possible by this system with less human dependence. Keywords: Short Message Service (SMS), Global System for Mobile communication (GSM), ubiquitous access and Automation. vi CONTENTS Pages Board of Examiners iii Declaration iv Acknowledgement v

    coverstory By Robert Cravotta, Technical Editor u WELCOME to the 31st annual EDN Microprocessor/Microcontroller Di- rectory. The number of companies and devices the directory lists continues to grow and change. The size of this year’s table of devices has grown more than NEW PROCESSOR OFFERINGS 25% from last year’s. Also, despite the fact that a number of companies have disappeared from the list, the number of companies participating in this year’s CONTINUE TO INCLUDE directory has still grown by 10%. So what? Should this growth and change in the companies and devices the directory lists mean anything to you? TARGETED, INTEGRATED One thing to note is that this year’s directory has experienced more compa- ny and product-line changes than the previous few years. One significant type PERIPHERAL SETS THAT SPAN of change is that more companies are publicly offering software-programma- ble processors. To clarify this fact, not every company that sells processor prod- ALL ARCHITECTURE SIZES. ucts decides to participate in the directory. One reason for not participating is that the companies are selling their processors only to specific customers and are not yet publicly offering those products. Some of the new companies par- ticipating in this year’s directory have recently begun making their processors available to the engineering public. Another type of change occurs when a company acquires another company or another company’s product line. Some of the acquired product lines are no longer available in their current form, such as the MediaQ processors that Nvidia acquired or the Triscend products that Arm acquired.

  • Datasheet CAN Driver Source Code
    Source Code CAN Driver Source Code - CANpie FD CAN driver for embedded applications The driver CANpie FD (Controller Area Network Program- ming Interface Environment) provides a standarized API for software engineering of CAN-based applications. The driver forms the basis for higher-layer protocols (CANopen / DeviceNet / J1939) and is available for a wide range of microcontroller platforms. Scalability and modu- lar design of the CANpie drivers facilitate implementation into individual target systems. Features • Modular design, scalable, easy to implement • Optimized for low resources (ROM / RAM) User Functions • Wide range of supported CAN controllers • Support of standard and extended frames (11-bit / 29-bit identifier) Core Functions Receive Transmit • Data flow by polling or interrupt driven FIFO FIFO • Supports virtual mailboxes Mailbox Access Filter Receive Transmit IRQ CAN hardware MicroControl GmbH & Co.

It soon of standardization of the on-chip debug and trace became clear that pure debuggers without trigger logic as well as a reduction in pincount without any and trace options were not adequate for developing performance loss. In order to take an active role PowerDebug complex embedded designs efficiently. The scope in the development of innovative debug and trace of on-chip debugging and trace interfaces has been technologies, Lauterbach has been participating enlarged gradually, enabling very complex test and in various international committees over the past PowerTrace analysis functions with today’s development tools. years: • Lauterbach has been a member of the Nexus 5001™ Forum ever since its foundation and was first to market with tools conforming to the PowerProbe NEXUS specification. • In the Test & Debug Working Group of the MIPI Alliance, Lauterbach has been involved in the Power- definition of interfaces as well as corresponding Integrator test and debug tools for mobile phones. • Lauterbach has been an active member of the IEEE P1149.7 Working Group for the definition of new JTAG standards ever since its foundation. In 2006 Lauterbach was able to significantly staff up its engineering departments, further strength- ening its leadership position in high performance development tools for a wide range of processor architectures.
