Dual-Core Multimedia AI Smart Frame & Islamic Calendar

Engineering a high-performance single-firmware appliance integrating a 10.1″ MIPI-DSI display pipeline, on-device neural wake word detection, dual-core coprocessing, and real-time cloud voice streaming.

01 // The Architecture Challenge

The system requirements mandated zero audio stuttering during simultaneous 1280x800 image decodes, live prayer time calculations with automated Adhan playback, and a real-time full-duplex conversational voice assistant powered by Xiaozhi and local WakeNet models.

MAIN SILICON // ESP32-P4
Dual-Core RISC-V + 32MB PSRAM

Drives 10.1″ MIPI-DSI, JPEG chunking, audio mixing, and neural voice detection.

WIRELESS CO-PROCESSOR // ESP32-C6
ESP-Hosted Over SDIO Bus

High-speed 4-bit SDIO transport (CLK 18, CMD 19, D0-D3) offloading network stacks.

02 // Firmware Innovations
  • Non-Blocking PSRAM Double-Buffering: Reads large photos in 256KB chunks, releasing the SD card bus between chunks so the audio task feeds playback buffers without starvation.
  • Local Neural WakeNet ("Jarvis"): Embedded 290KB ESP-SR model running in a background task; zero microphone audio streams to the cloud until wake-word activation.
  • Full-Duplex Opus Streaming: Microphone data captured at 48kHz, downsampled to 16kHz, Opus-encoded in 60ms frames, and piped over WebSockets to Xiaozhi.
  • Dual-Slot Fail-Safe OTA: 16MB flash mapped with active (app0) and backup (app1) slots, allowing browser-based remote updates with rollback protection.
Bench Delivery Result

Unified 5.8MB PlatformIO Image

All drivers, MIPI-DSI graphics, multi-touch tracking, SDIO networking, audio decoders, and voice assistants run reliably from a single production-ready binary.

Direct Engineering Leadership

Meet the Founder & Lead Systems Architect

No account executives, no junior delegation. Your hardware is scoped, routed, and bench-tested directly by an experienced engineer.

Mustafa Husain - Founder & Lead Systems Architect at ProtoForge

Founder & Principal Systems Architect
Active on the Bench • Slough Lab

Hardware prototypes shouldn't be trapped in bureaucratic development cycles or multi-month agency backlogs. At ProtoForge, I partner directly with founders, R&D teams, and hardware pioneers to compress early-stage development from quarters into weeks.

My approach combines rigorous embedded firmware design with high-speed PCB layouts and end-to-end IoT connectivity. Every design is built with Design for Manufacturability (DFM) from day one—ensuring your proof-of-concept doesn't require a total redesign when transitioning to volume manufacturing.

Direct Technical Scoping

You communicate directly with the person routing your traces and testing your firmware on the oscilloscope.

Unrestricted IP Independence

You retain 100% unencumbered rights to native CAD files, firmware Git repos, and manufacturing BOMs.
