Sensor Watch

Sensor-Watch is an open-source programmable replacement circuit board that transforms a classic digital watch into an extensible wrist-worn development computer. It functions as an embedded firmware development kit, providing the toolset needed to compile and install custom C software onto resource-constrained microcontrollers through a standard bootloader mechanism.

The platform supports peripheral pin multiplexing to route analog, digital, and communication signals through a physical multi-pin expansion interface connected to the core processor. This enables the integration of custom peripheral boards and external hardware sensors, alongside segmented LCD frame buffering that maps virtual display segments directly to hardware memory addresses.

Development workflows include a browser-based hardware simulator that runs compiled runtime logic to simulate low-level microcontroller peripherals and screen output locally. User interface components are structured as modular watch faces using interchangeable state machines that hook into a central event loop, allowing developers to verify visual modifications before deploying binaries to physical hardware.

    Porffor is an ahead-of-time compiler that converts JavaScript and TypeScript source code into native machine code or C binaries. It functions as a native binary generator and transpiler, producing standalone executable files that do not require a runtime or virtual machine. The project translates source code into C language files and WebAssembly binary formats. It includes a direct-to-binary pipeline for TypeScript, allowing for the generation of target executables without a separate transpilation step to JavaScript. The toolset also includes an interactive read-eval-print loop for real-time
