This application note describes the design, development
and implementation of a smart, low-cost, stand-alone
Controller Area Network (CAN) node. It combines the
Microchip 8-pin PIC12C672 microcontroller and the
Microchip 18-pin MCP2515 Stand-Alone CAN controller.
This creates a fully autonomous CAN node, which
supports both “time-based” and “event driven” message
transmission.
The node is interrupt driven, capable of monitoring five
external inputs (two analog and three digital) and
automatically generating messages based upon their
value. The node also controls two digital outputs,
responding to message requests via the CAN network
and generating a repeating, time-based message. AN215
