Thanks to several enhancements, Crossware's ARM Development Suite is able to simulate controller-area-network (CAN) controller peripherals of NXP Semiconductors' LPC2119, LPC2129 and LPC2194 microprocessors. The Crossware ARM Development Suite simulates all aspects of a CAN controller and generates a stream of output bits. This bit stream is transferred to a simulating CAN bus, where it's merged with the bit streams of other simulating CAN controllers. The merged bit stream is reflected back to all CAN controllers, allowing each to win or lose arbitration, transmit and receive data, provide a signal acknowledgement or error status, etc.
The Crossware Code Creation Wizards will create code for the CAN controllers, as well as for the acceptance filter, message identifiers, message data, etc. By using these wizards, code to transmit and receive a message can be generated in minutes without manually writing a single line of code. The program can then be built, and seconds later, the developer sees the transmitted message. The message appears on the simulating CAN bus and is received and acknowledged by the receiver. Also, the easy-to-use Crossware suite abstracts the developer from the complexity of the CAN bus code.
