The encoder is polled by a periodic esp_timer, so the pins do not have to be interrupt capable and several encoders work at the same time. The polling interval is a build time constant, `CONFIG_RE_INTERVAL_US`, which also sets the granularity of the button timings. The events are reported from the timer task, so the callback has to be quick and must not call back into the driver; see the documentation of the callback type before using it. * [Documentation](https://esp-idf-lib.github.io/encoder/) * [Repository](https://github.com/esp-idf-lib/encoder) * [Issues](https://github.com/esp-idf-lib/encoder/issues) * [Discussions and questions](https://github.com/esp-idf-lib/core/discussions) * [Component page at the ESP Component Registry](https://components.espressif.com/components/esp-idf-lib/encoder) ## Installation ```sh idf.py add-dependency esp-idf-lib/encoder ``` ## Support For questions and discussions about the component, please use [Discussions](https://github.com/esp-idf-lib/core/discussions) at [esp-idf-lib/core](https://github.com/esp-idf-lib/core). ## Contributing Please read [CONTRIBUTING.md](https://github.com/esp-idf-lib/core/blob/main/CONTRIBUTING.md) at [esp-idf-lib/core](https://github.com/esp-idf-lib/core).
