CAN-Engine

A Controller Area Network (CAN) controller (SJA1000, 20 MHz clock) can be installed along with on-board CAN transceiver. Supported baud rates range from 300 bps to 1 Mbps, and interrupt-driven buffering software allows reliable, efficient delivery and receipt of packets over the CAN network. CAN control egisters on the SJA1000 are accessible in software.A Fast Ethernet Module can also be installed to provide 100M BaseT network connectivity. This Ethernet module has a hardware LSI TCP/IP stack. It implements TCP/IP, UDP, ICMP and ARP in hardware, supporting internet protocol DLC and MAC. The hardware Ethernet module releases internet connectivity and protocol processing from the host processor, which represents a huge improvement over software-based TCP/IP stacks. The resulting system can easily handle transmissions in the 100KB/s+ range in real world applications. It supports 4 independent stack connections simultaneously at a 4Mbps protocol processing speed. Software libraries and demo project are available for Ethernet connectivity.A 16-bit parallel ADC (AD7655, 0-5V) supports ultra high-speed (1 MHz conversion rate) analog signal acquisition. The AD7655 contains two low noise, high bandwidth track-and-hold amplifiers that allow simultaneous sampling on two channels. Each track-and hold amplifier has a multiplexer in front to provide a total of 4 channels analog inputs. The 16-bit parallel ADC requires only two CPU I/O operations (one start, one read) to complete a 16-bit ADC reading. With on-board precision 2.5V reference, the ADC accepts 0-5V analog inputs at 16-bit resolution of 0-65,535.  Two 12-bit DACs provide 0-4.095V analog voltage outputs capable of sinking or source upto 5mA.The CANE supports up to 2 GB mass storage CompactFlash cards with Windows compatible FAT filesystem support, allowing user easily transfer large amounts of data to or from a PC.The CANE features fast execution times through 16-bit ACTF Flash (256 KW) and battery-backed SRAM (256 KW). It also includes 3 timers, PWMs, 20+ PIOs, 512-byte serial EEPROM, two RS232 ports, 3 timer/counters, and a watchdog timer. The three 16-bit timers can be used to count or time external events, up to 10 MHz, or to generate non-repetitive or variable-duty-cycle waveforms as PWM outputs. The PIO pins are multifunctional and user programmable. A real time clock (DS1337, Dallas) is available.The CANE can be powered by regulated 5V DC or unregulated 9-12V DC with installing a 5V regulator. The CANE works with TERN expansion boards including the P52, P100 and MotionC.
