I’m putting together a small project that blends two areas: a lightweight mobile-side application and the embedded firmware that sits on the target hardware. In practice, that means I’ll supply the hardware specs and communication protocol; you’ll take it from there by writing clean, well-documented embedded code (C/C++ or a comparable language) and a minimal companion app that proves everything talks together as intended. The flow I have in mind is simple: flash the board, pair it with the mobile app, verify data exchange, and hand back the full source plus build instructions so I can replicate it on my end. If you’re comfortable moving quickly between low-level registers and a touch-friendly UI, this will be straightforward work. Key deliverables • Compilable embedded firmware with inline comments • Companion mobile app (Android or iOS—whichever stack you prefer) • Read-me or short build guide so I can reproduce the binaries • A brief validation video or screenshots showing successful end-to-end communication That’s the entire scope; let me know which toolchains you prefer and how soon you can start.
