MCUXpresso SDK board support package folders {#GUID-C94377D8-C1BD-4591-A460-92AF83ADAC3C}
MCUXpresso SDK board support package provides example applications for NXP development and evaluation boards for Arm Cortex-M cores including Freedom, Tower System, and LPCXpresso boards. Board support packages are found inside the top level boards folder and each supported board has its own folder (an MCUXpresso SDK package can support multiple boards). Within each <board_name> folder, there are various sub-folders to classify the type of examples it contain. These include (but are not limited to):
cmsis_driver_examples: Simple applications intended to show how to use CMSIS drivers.demo_apps: Full-featured applications that highlight key functionality and use cases of the target MCU. These applications typically use multiple MCU peripherals and may leverage stacks and middleware.driver_examples: Simple applications that show how to use the MCUXpresso SDK’s peripheral drivers for a single use case. These applications typically only use a single peripheral but there are cases where multiple peripherals are used (for example, SPI conversion using DMA).emwin_examples: Applications that use the emWin GUI widgets.rtos_examples: Basic FreeRTOS OS examples that show the use of various RTOS objects (semaphores, queues, and so on) and interfaces with the MCUXpresso SDK’s RTOS driversusb_examples: Applications that use the USB host/device/OTG stack.
