The picture above shows how to connect the CANDIP/AVR1 and external components needed. Dashed blocks are optional connections depending on your application. The CANDIP/AVR1 supports In-System-Programming (ISP) through the SPI port and it supports the STK200/300 programmer from Atmel/Kanda or the AVR-ISP-GOLD from Kanda (provided with CANDIP as an option).
The picture above shows the internal block diagram of CANDIP/AVR1. The real schematic of the CANDIP/AVR1 is not included since it is an end product. The CANDIP/AVR1 includes a diskette with sample programs, manuals and demo software for the WiCAN CAN library. The CAN controller is reachable from 0x0000-0x7FFF (decoded by A15), but first after the internal RAM of the 8515. The INT0 of the 8515 is connected to the SJA1000 Interrupt line for interrupt driven CAN.
Just see how small the CANDIP/AVR1 is. CANDIP/AVR1 is perfect for small systems such as Home Automation, small and effective CAN nodes with e.g. digital I/O or Analog I/O, use it for expanding your existing embedded system through the SPI or RS-232 channel. It can also be used for simple test and learning CAN. The CANDIP/AVR1 is easy to expand into a large system through the SPI port or via software controlled I2C.
