Focused components for embedded products that need to persist state, recover from interruption and expose useful operational evidence.
The family map describes product areas. It does not imply that every component is a runtime dependency of another.
LOX DB brings key-value, time-series and small relational engines together with an optional write-ahead log and a storage hardware abstraction layer. Its stated target is predictable memory on constrained firmware.
Stable · v1.5.3 · MIT · C99A separate commercial repository publishes integration documentation for independently selected modules around the LOX DB core. Its implementation is not part of the public source repository.
Commercial · public integration documentationEach module is an individual repository and page. The groups describe its primary discovery area, not a dependency chain.
Predictable-memory C99 database with key-value, time-series and small relational engines, optional WAL recovery, and direct installation from PlatformIO or the Arduino Library Manager.
Product detailsLOX DB Pro is a commercially licensed, pick-and-choose set of independent C modules delivered as CMake targets in the loxdb namespace. The public repository documents integration-facing contracts; implementation, source code and proprietary know-how remain private.
Product detailsA portable object store registers fixed objects, computes deterministic layout and exposes format, mount, propose, check and repair operations.
Product detailsPure C99, MIT trainable frequency-optimized text codec with v2 and matrix-based v3 formats, including HIER4/HIER8 nested matrices.
Product detailsA deterministic alarm lifecycle adds delays, latching, acknowledge, shelving and portable snapshots to caller-supplied conditions.
Product detailsA C99 bootloader core provides A/B state, UART update transport and adapter boundaries.
Product detailsGuard Blocks wrap documented host-tested execution paths, record evidence and route failures to configured policy actions.
Product detailsA header-only evaluator qualifies inputs, latches denials, records first-out state and supports controlled bypass metadata.
Product detailsA heap-free step sequencer writes CRC-protected checkpoints and computes a conservative recovery verdict on boot.
Product detailsA caller-owned admission controller returns an explicit allow, degrade, defer or deny decision before work starts.
Product detailsA stateless dispatcher selects among eligible C99 algorithms using explicit constraints and an offline profile.
