The number of globally connected IoT devices continues to rise every year. The power requirements faced by them have evolved beyond the limitations brought by the usage of batteries as the main energy source. This has paved the way for the development of a new type of power supply: energy harvesting. New challenges arose alongside it, including the intermittent operation of computer systems sustained by it. Many solutions have been presented, but related works lacked easily comparable parameters for studying their efficiency, as energy harvesting applications vary considerably. Therefore, a control interface was proposed to facilitate integration between strategies for intermittent computing and energy management. The implemented design focused more on the execution control of the microcontroller, but was evaluated experimentally with a real energy harvester. Despite the difficulties with energy harvesting architecture, a suitable solution was reached, leaving room for improvement in future works.
