The team spent one week describing their hardware in the board.efrpme file. They then used the legacy import tool ( efrpme migrate --legacy pic18_project/ ) which analyzed the old code and generated equivalent EFRPME event blocks. In two weeks, they had a working prototype on the STM32. Common Misconceptions About EFRPME Myth 1: "EFRPME adds overhead." Reality: The event-driven scheduler is written in hand-optimized assembly for each core. Idle power draw is often lower than hand-coded polling loops because the core sleeps 99.9% of the time.
Reality: Major automotive and aerospace suppliers use EFRPME derivatives for safety-critical systems. The code generation is deterministic and certifiable (ISO 26262 ASIL-D ready). efrpme easy firmware work
