PTIObased

PTIObased is a framework of software and hardware integration designed to streamline the input-output operations of embedded systems. The acronym PTIObased stands for Protech Input/Output Based Architecture, and the system was first introduced in 2018 by the multinational electronics firm Protech Dynamics. The development of PTIObased was driven by the increasing demand for real‑time data processing in automotive, aerospace, and industrial automation applications. Protech Dynamics released the first open‑source specification in 2020 to encourage wider adoption and community development.

The core concept of PTIObased is to decouple application logic from physical I/O handling by using a layered abstraction model. At the lowest level, the hardware adapter layer manages vendor‑specific bus protocols such as SPI, I²C, UART, and CAN. Above this, a standardized I/O service layer exposes the hardware functions through a set of APIs that can be consumed by applications written in C, C++, or Python. The topmost layer allows developers to compose high‑level I/O components (e.g., sensor fusion modules, motor control loops) without needing to understand the underlying bus intricacies. This separation increases code reusability and eases firmware updates.

PTIObased is licensed under the GNU GPL v3 and has gained a modest following in the maker and defense contractor communities. Notable deployments include a prototype autonomous drone platform, where PTIObased's modularity reduced development time by approximately 30%, and a factory line monitoring system that integrates with existing PLCs more seamlessly than traditional middleware. A small but active developer forum supports contributions, bug fixes, and feature requests. Despite its niche area, PTIObased exemplifies a move toward standardized, modular I/O handling in embedded system design.
