USB applications

NXP’s USB 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 developers to quickly and easily configure USB drivers for their 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 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 along with fully-functional example applications that implement CANopen devices and managers. EmSA has made their CANopen Architect Software available as a free download to help you go beyond the examples and generate custom configurations. In addition to CANopen, EmSA’s implementations also support CANopen FD which will be available in later in 2020.

  • CANopen Device library and CANopen 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.

Ethernet applications

NXP’s Ethernet driver and middleware libraries are provided with full source code, 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 and WolfSSL (evaluation version)
  • DHCP and static IP allocation
  • TCP
  • UDP
  • MQTT
