Our Micro CANopen Plus source code implements the most often used functions of the CANopen protcol stack. Drivers included are for NXP LPC ARM Cortex devices and the CANopen Magic simulation system.

MicroCANopen Plus is a small-footprint, commercial-grade CANopen source code implementation with advanced features. Ideal for situations requiring medium configurability during run-time and great performance on any type of platform, and for building networks that include manager nodes, MicroCANopen Plus provides the most flexible solution. Auto-generated configuration from the EDS/DCF file makes its setup a quick and painless one-step process.

Portable. MicroCANopen Plus is written in 100% standard ANSI C code allowing for straightforward porting. For targets without standard support packages, designers familiar with their target processor can easily perform the port themselves. Or, ask us for a quote to add support to your target!

Compact. ROM Specifications: 7K - 14K bytes (for basic CANopen devices/sensors) depending upon processor and options selected.

An Affordable Pricing Structure. MicroCANopen Plus offers a low, one-time fee and no royalties on deployed products and includes all source code with every purchase.
