This application report presents an introduction to the CAN fundamentals, operating principles, and the implementation of a basic CAN bus with TI's CAN transceivers and DSPs.

Dec 27, 2002 · The CAN module must be initialized before it can transmit/receive message packets over the CAN bus. This is done by writing the appropriate values to the various configuration and control …

The ISO 15765 protocol stack was designed by Simma Software, the CAN experts, and has been used in more than a million ECUs. The protocol stack abstracts away the technical details and complexity …

lwIP is a widely used open-source independent lightweight implementation of the TCP/IP protocol stack designed for resource-constrained embedded systems. Some advantages of lwIP are discussed below:

Figure 1 shows a typical I2C bus for an embedded system, where multiple slave devices are used. The microcontroller represents the I2C master, and controls the IO expanders, various sensors, …

The CAN solution to this is prioritized arbitration (and for the dominant message delay free), making CAN very suitable for real time prioritized communications systems.

Introduction The CAN standard specifies the data link layer between nodes. This document will specify the higher level protocol used for communication between applications running on the nodes.

The expander part declares the basic variables, GPIO configuration function, and interrupt function, and expander also contains some basic functions for SPI, I2C and UART protocol.

ABSTRACT Communication between microcontrollers and different peripheral devices require some sort of digital protocol. I2C is a common communication protocol that is used in a variety of devices from …

In CAN protocol, any transmitting node monitors its own transmission. This is required in order to facilitate non-destructive bit-wise arbitration, ascertain acknowledgement of a frame (ACK) by other …
