Examples

Every example here is a real NSX app: an nsx.yml, a CMakeLists.txt and source, built by the same commands as an app you generate. They are the fastest way to see how a capability is wired before you wire it yourself.

From a source checkout you can build any of them by name, because the positional app argument resolves under ./examples:

nsx build hello_world --board apollo510_evb

Several declare more than one target, so --board picks which one you are building. See Boards and targets.

What each one covers

Example	Tier	Status	Capabilities	Boards tested
FreeRTOS Blinky	Basics	tested	freertos, rtos	apollo510_evb
Hello World	Basics	tested	swo, printf	apollo510_evb
USB Serial	Basics	tested	usb, cdc-acm	apollo510_evb
Audio Capture	Capabilities	tested	audio, pdm	apollo510_evb
CoreMark	Capabilities	builds	benchmark, rtt, itcm	none declared
PMU Profiling	Capabilities	tested	pmu, profiling	apollo510_evb
Power Benchmark	Capabilities	builds	power, gpio, timer	none declared
BLE Webble	Integrations	experimental	ble, cordio, freertos	apollo3p_evb, apollo4p_blue_kxr_evb, apollo510b_evb
KWS Inference	Integrations	tested	ml, tflite, cmsis-nn, helia-rt	apollo510_evb
USB RPC	Integrations	tested	usb, rpc, nanopb	apollo510_evb

Every column in that table comes from the example’s own front matter. Tier is the reading order: Basics first, then Capabilities one at a time, then Integrations that compose several. Status and Boards tested are the author’s declaration of what they ran and where, not a test record this site holds, so treat a “none declared” boards column as “not stated” rather than as “does not work”.

Where to start

• New to NSX: Hello World, then FreeRTOS Blinky.
• Measuring something: PMU Profiling, Power Benchmark and CoreMark.
• Running a model: KWS Inference.
• Talking to a host: USB Serial, USB RPC and BLE Webble.
• Reading a sensor: Audio Capture.
