CAN and CAN-FD Applications

NXP has partnered with Embedded Systems Academy (EmSA) to offer CANopen and CANopen FD libraries based on its Micro CANopen Plus stack for our CAN / CAN-FD enabled microcontrollers. These libraries are free to use, and available through the MCUXpresso SDK with fully-functional example applications that implement CANopen and CANopen FD devices and managers. EmSA has made their CANopen Architect Software available as a complimentary download to help you go beyond the examples and generate custom configurations.

• CANopen device library and CANopen manager library
• CANopen FD device library and CANopen FD manager library
• Functionality suitable for simple I/O devices and control applications that can pass the official CANopen conformance test (extended functionality libraries available from EmSA)
• Object dictionary contents can be freely configured using EmSA’s CANopen architect standard EDS editor
• Compatible with CANopen monitoring, configuration or analysis tools such as CANopen magic

EmSA’s stacks utilize NXP’s CAN and CAN-FD SDK drivers, which are provided with full source code and basic examples.

AVB and TSN

NXP's GenAVB/TSN Stack is a set of software components which provides Time Sensitive Network (TSN) and Audio Video Bridging (AVB) functionality on supported NXP microcontrollers. These stacks and provided example applications are free to use, support FreeRTOS applications and are compatible with the MCUXpresso SDK. Example applications are provided in source code and illustrate various TSN and AVB use cases.

The AVB/TSN packages are currently only available as an add-on package for supported platforms. Please see the Downloads tab to access these packages.

• Layer 2 socket API
• gPTP based clock and timer API's
• OS abstraction layer

The AVB package adds:

• Forwarding and queuing for time-sensitive streams (IEEE 802.1Q-2018, section 34)
• Audio video transport protocol (AVTP) (IEEE 1722-2016)
• Audio video device discovery, enumeration, connection management and control protocol (AVDECC) (IEEE 1722.1-2013)
• AVB control and streaming API's
