neuralspotx

CI Pages Release

neuralspotx is the NSX tooling repo.

NSX is a lightweight bare-metal workflow for Ambiq targets. It provides:

  • the nsx CLI
  • packaged app templates
  • packaged CMake helpers
  • built-in board definitions
  • curated metadata for module and SDK selection

The primary audience is app developers creating small, focused NSX applications for bring-up, profiling, validation, and simple demos.

NSX is also the build-and-deploy vehicle for Ambiq's Helia AI stack:

  • heliaRT — optimized LiteRT (TFLite Micro) runtime, shipped as an NSX module
  • heliaAOT — ahead-of-time compiler that generates NSX modules from .tflite models
  • heliaPROFILER — on-device model profiler built on NSX

For contributor workflows such as releases, CI, and the Python API surface, use the docs site under docs/.

Documentation

The main documentation lives in the docs site built from docs/.

Install the docs toolchain:

cd <nsx-repo>
uv sync --group docs

Run the docs site locally:

cd <nsx-repo>
uv run --group docs zensical serve

Build the static site:

cd <nsx-repo>
uv run --group docs zensical build

Quick Start

NSX uses an app-first flow. Each app is a self-contained project directory with vendored modules, board definitions, and build helpers.

For app users, the cleanest install path is pipx:

pipx install neuralspotx
nsx doctor
nsx create-app hello_ap510 --board apollo510_evb

For contributors working from a source checkout:

cd <nsx-repo>
uv sync
source .venv/bin/activate
nsx doctor
nsx create-app hello_ap510 --board apollo510_evb

Build the app:

nsx configure --app-dir hello_ap510
nsx build --app-dir hello_ap510

Repo Scope

This repo owns:

  • src/neuralspotx
  • packaged documentation and templates
  • packaged board definitions
  • CMake helper assets used by generated apps

Built-in firmware modules are described by the packaged registry and fetched from their default upstream repos as needed. Normal app users create standalone app directories and let NSX manage module resolution, vendoring, configuration, build, flash, and view flows.
