NSX

Examples

Examples¶

Eight ready-to-build example apps ship in the examples/ directory. Each one is a self-contained NSX app — clone the repo and you can configure, build, and flash immediately.

All examples target the Apollo510 EVB (apollo510_evb profile).

Quick Start¶

git clone https://github.com/AmbiqAI/neuralspotx.git
cd neuralspotx/examples/hello_world

nsx configure --app-dir .
nsx build     --app-dir .
nsx flash     --app-dir .   # requires J-Link
nsx view      --app-dir .   # live SWO stream
