Overview

This user guide provides technical instructions for using the IEC60730B Safety library with NXP LPC55Sxx microcontrollers, including the LPC55S69, LPC55S36, and LPC55S28. It details hardware configuration requirements for LPCXpresso evaluation boards, specifically focusing on debugger settings, resistor voltage divider setups for analog I/O tests, and FreeMASTER communication. The document explains the integration of safety middleware within the MCUXpresso SDK, covering project structure, library handling code, and configuration of core safety tests such as ADC, Clock, DIO, Flash, RAM, Program Counter (PC), and Watchdog timers. Support for IAR, Keil MDK, and MCUXpresso IDEs is included.

Use Cases

  • Developing Class B safety-compliant software for industrial and consumer electronics
  • Configuring LPCXpresso55Sxx development boards for functional safety testing
  • Implementing self-test routines for MCU core, memory, and peripherals
  • Integrating the NXP IEC60730B safety library into MCUXpresso, IAR, or Keil MDK projects
