Wired Communications Middleware for NXP Microcontrollers

USB Applications

NXP’s USB applications host and device libraries are provided with full source code and a wide range of examples. The MCUXpresso SDK default configurations include all of the necessary drivers and several example applications to help you take full advantage of USB features, and the MCUXpresso peripheral tools enable you to quickly and easily configure USB drivers for your application needs. Examples are provided as bare metal and RTOS-based implementations, with build options for full- and high-speed USB.

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.

*Functionality may not be available on all parts within each family listed above.

Ethernet Applications

NXP's Ethernet driver and middleware libraries are provided with full source code - complete with driver and network interface-level applications. Examples are based on the popular, open-source LWIP TCP/IP library and are provided as bare metal and RTOS-based implementations. In addition, full cloud-connected applications are provided for select platforms. Examples provided show use of most commonly used networking elements:

• HTTP server with and secure HTTP server using MbedTLS
• DHCP and static IP allocation
• TCP
• UDP
• MQTT

TSN

NXP's TSN Stack is a set of software components that provides Time-Sensitive Networking (TSN) functionality on supported NXP microcontrollers. The stack, along with the provided example applications, is free to use, supports FreeRTOS-based applications, and is compatible with the MCUXpresso SDK. The example applications are provided in source code and illustrate a range of TSN use cases.

The TSN package is currently available only as an add-on package for supported platforms. Please refer to the Downloads tab to access the available packages.

The TSN package provides:

• Generalized precision time protocol (gPTP) (IEEE 802.1AS-2020)
• Enhancements for scheduled traffic API's (IEEE 802.1Q-2018, section 5.25, a.k.a. IEEE 802.1Qbv)
• Frame pre-emption API's (IEEE 802.1Q 2018, section 5.26, a.k.a. IEEE 802.1Qbu-2016 and IEEE802.3br-2016)
• Per Stream Filtering and Policing API’s (IEEE 802.1Qci-2017)
• Frame Replication and Elimination for Reliability (IEEE 802.1CB-2017)
• Stream reservation protocol (SRP) (IEEE 802.1Q-2018, section 35, a.k.a. IEEE 802.1Qat)
• Layer 2 socket API
• gPTP based clock and timer API's
• OS abstraction layer
