At first CAN was only designed to solve the issues regarding the wiring in automobiles. Twisted-pair cables are being used in Controller area networks to set up communication between two nodes and the data rate it provides is nearly 1 Mbits/sec and is able to connect upto 40 devices at once.
LCD DISPLAY LPC2129 SERIAL
Software Module mainly consists of the following components such as CAN initialization unit, message sending and receiving units and the interrupt service unit.Ĭontroller Area Network is a fast serial data bus whose sole function is to enable reliablility, efficiency and a very advanced communication between sensors and actuators.
Software functions are dealing with the setting up of data transmission between different nodes and thus the transmission of data from node to node. Here in the hardware we are using ARM7 mainly, CAN communication controller, along with LPC2129 and design schematic circuit diagram relating CAN bus system hardware. The functions are been done by CAN protocol and it helps in the designing of both hardware and software of the expected system. This has been built upon the base of ARM where we use ADC to convert the received data from analog signal to digital signal and this is fed to the LCD display. Here an attempt is done in the direction of development and implementation of a semi-autonomous electric vehicle to increase the efficiency of the vehicle-user interface. Digital instruments that are multifunctional are used for improved precision. Nowadays most of these mechanical systems are being replaced by electrical parts and they provide better performance and efficiency. But it had too many restrictions and hence increased complexity cause of too many performance indexes needed to be taken care of. Introductionįor years in automotive field, mechanical parts of the moving coil type or magnetomotive machines were used. From the actual measurement results, the hardware indicators of the LCD instrument display system fully meet the basic requirements of the design. This can be made used to design significant interface circuits such as data acquisition and control signal interface, power supply module, speed odometer interface, engine speed interface, oil instructions interface, water temperature interface, car battery charger power connector and other important nodes in the vehicle interface circuit. This system mainly concentrates on the design of hardware of the display system for the pure electric vehicle and the interface system designing is also done taking the features of embedded systems. To transmit a message signal in practical conditions under poor environment is difficult, so reliability and stability are most important factors. The proposed display system has a great reliability and stability in addition to it’s given function in an Electric vehicle.
