As a typical application layer protocol of CAN-bus, CANopen has been widely accepted in many fields. In this paper, CanFestival, which is a kind of open-source CANopen stack, is briefly introduced. The implementation scheme of CANopen slave node is proposed, which is based on a kind of AVR microcontroller-AT90CAN128 and open-source CANopen stack-CanFestival. In this paper the hardware design of slave node and the open-source protocol stack transplant have completed successfully. The debugging experiment of this slave node communication has been carried out, and the correctness of the scheme of hardware design and software transplant is verified by debugging experiment results in this paper.

Embedded systems are nowadays employed in a wide range of application, and their capability to implement calculation-intensive algorithms is growing quickly and constantly. This result is obtained by the exploitation of powerful embedded processors that are often connected to coprocessors optimized for a particular application. This work presents an open-source coprocessor dedicated to the real-time generation of a synthetic signal that mimics the echoes produced by a moving fluid when investigated by ultrasounds. The coprocessor is implemented in a Field Programmable Gate Array (FPGA) device and integrated in an embedded system. The system can replace the complex and inaccurate flow-rigs employed in laboratorial tests of Doppler ultrasound systems and methods. This paper details the coprocessor and its standard interfaces, and shows how it can be integrated in the wider architecture of an embedded system. Experiments showed its capability to emulate a fluid flowing in a pipe when investigated by an echographic Doppler system.

G-bios is a type of Bootloader and its code is open source. Bootloader is one of the important parts of the embedded system for its booting and loading operating systems function. The design and implementation of interrupt in Bootloader and the improvement of the systems execution efficiency is the innovative point of this paper.

U-boot is an open source project under the protocol of GPL, which has been widely used as boot application on embedded system. Normally, U-boot initializes hardware and send to hardware information to the embedded OS. In mobile thermals, especially in the arm-based mobile device, U-boot has played an important role. U-boot supports many kinds of development boards. However it does not support every board, so it needs to be modified to fit other board. This paper analyses the boot procedure and the source code of U-boot, studies how to add a custom command on U-boot source, analyses the protocol of USB, then gives us a new way to download the binary U-boot file or the kernel directly to RAM and run. In this way, we do not need to burn the binary U-boot file or the kernel to Flash. This has save a lot of time in embedded system development.

In this paper, we have described an operative prototype for Internet of Things (IoT) used for consistent monitoring various environmental sensors by means of low cost open source embedded system. The explanation about the unified network construction and the interconnecting devices for the consistent measurement of environmental parameters by various sensors and broadcast of data through internet is being presented. The framework of the monitoring system is based on a combination of embedded sensing units, information structure for data collection, and intellectual and context responsiveness. The projected system does not involve a devoted server computer with respect to analogous systems and offers a light weight communication protocol to monitor environment data using sensors. Outcomes are inspiring as the consistency of sensing information broadcast through the projected unified network construction is very much reliable. The prototype was experienced to create real-time graphical information rather than a test bed set-up.


Embedded system today are influencing every sphere of life and all application domains. These systems were initially designed according to the application requirement as special hardware. This approach of embedded system design was influenced by particular family of processor. The new approach of embedded system design envisages the use of general purpose on the shelf hardware modules to be incorporated. These on the shelf hardware modules are also referred open source hardware platforms as their entire hardware module design in available in public domain. Thus populating such hardware platforms by different individuals becomes easy. At instances these open source modules are not as good as the original ones. This is because calculating and predicting the successes achieved or failure caused by the copy is not tested. This can be verified by the performance of the module designed in terms of reliability

Simulation tools help creating a low cost and efficient development of embedded system. SID is an open source simulator software that consists library of components for modelling hardware and software components. A component can be written in C/C++ and Tcl/Tk. Currently, the SID simulation toolkit only provides support for C++ and Tcl/Tk. Tcl/Tk is used to create GUI-based components. However, we have observed that Tcl/Tk components causing slow simulation response. Developing GUI using Tcl/Tk is also inflexible. Thus it is not proper for developing the cutting-edge products with rich graphics. In this work, we introduced the idea of Java as an alternative platform for developing components in SID. We suggest two design approaches for Java Bridge module for SID. One is the approach based on socket communication, and the other is based on JNI. SID API for Java component development is also proposed to ensure the compatibility and simplicity of SID components in Java. Key-Words: - Embedded system, Simulator, SIDd, Bridge component, Java, Software

In this paper, an open source web service software—gSOAP which is transplanted to the embedded Linux is proposed. Web service is not only an application entity for building applications, but also a distributed applications platform which runs operations interoperably. It can also execute all kinds of operating systems (OS) which support HTTP protocol. With the rapid development of the embedded system, lots of open-source software is transplanted to the embedded platform by embedded operating systems.
