Trying to compile IRrecvDumpV3 with Espressif Arduino 3.0.0 alpha is generating this compile errors
The Timer API has changed. Arduino 3.0.0 is based on IDF 5.1. We (Tasmota crew) tried to adopt to the new API
It does compile, but it seems there are now timing issues. The recognition result are terrible.
