Source Code CAN Driver Source Code - CANpie FD CAN driver for embedded applications The driver CANpie FD (Controller Area Network Program- ming Interface Environment) provides a standarized API for software engineering of CAN-based applications. The driver forms the basis for higher-layer protocols (CANopen / DeviceNet / J1939) and is available for a wide range of microcontroller platforms. Scalability and modu- lar design of the CANpie drivers facilitate implementation into individual target systems. Features • Modular design, scalable, easy to implement • Optimized for low resources (ROM / RAM) User Functions • Wide range of supported CAN controllers • Support of standard and extended frames (11-bit / 29-bit identifier) Core Functions Receive Transmit • Data flow by polling or interrupt driven FIFO FIFO • Supports virtual mailboxes Mailbox Access Filter Receive Transmit IRQ CAN hardware MicroControl GmbH & Co.
