Stuttgart, 2026-09-10 – Vector is releasing Chiisai, a fully open and royalty-free specification that fundamentally simplifies the development of hardware abstraction layers (HAL) on small microcontrollers. Chiisai aims to keep HAL implementations deliberately lean: the specification focuses on essential basic functions, thereby reducing the software footprint and supporting the efficient use of resource-constrained microcontrollers.
