💡 What: The optimization caches the result of
millis()into a local variablenowat the start ofABounce::update()and passes it to thedebounce()helper method.🎯 Why:
millis()was being called multiple times within a singleupdate()cycle (up to three times). Caching it reduces function call overhead and ensures timing consistency within a single scan.📊 Measured Improvement: In a simulated environment using a g++ benchmark with 10 million iterations:
update()call (no state change) decreased from ~11.7ns to ~8.5ns (~27% improvement).update()call (with rebounce active) decreased from ~15.0ns to ~8.9ns (~40% improvement).PR created automatically by Jules for task 753176063983936865 started by @prestalab
