The Blinky project can be easily used to verify the basic tool setup.
It is compliant to the Cortex Microcontroller Software Interface Standard (CMSIS) and uses the CMSIS-RTOS v2 API for RTOS functionality. The CMSIS-RTOS v2 API is supported by various real-time operating systems, for example Keil RTX5 or FreeRTOS.
- At start the
vioLED0blinks in 1 sec interval. - The
vioBUTTON0changes the blink frequency and start/stopsvioLED1.
The board hardware mapping of vioLED0, vioLED1, and vioBUTTON0 depends on the
configuration of the CMSIS-Driver VIO.
The real-time operating system Keil RTX5 implements the resource management.
It is configured with the following settings:
- Global Dynamic Memory size: 24000 bytes
- Default Thread Stack size: 3072 bytes
- Event Recorder Configuration
- Global Initialization: 1
- Start Recording: 1
- Global Initialization: 1
Refer to Configure RTX v5 for a detailed description of all configuration options.
The tables below list the device configuration for this board. The board layer for the NXP LPCXpresso55S69 is using the software component ::Board Support: SDK Project Template: project_template (Variant: lpcxpresso55s69) from NXP.LPCXpresso55S69_BSP.12.4.0 pack.
The heap/stack setup and the CMSIS-Driver assignment is in configuration files of related software components.
The example project can be re-configured to work on custom hardware. Refer to "Configuring Example Projects with MCUXpresso Config Tools" for information.
