# ESP32Encoder
[![Build Status](https://travis-ci.com/madhephaestus/ESP32Encoder.svg?branch=master)](https://travis-ci.com/github/madhephaestus/ESP32Encoder)
ESP32Encoder library that uses the ESP32 pulse counter hardware peripheral:
https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/pcnt.html
There is only one interrupt for the peripheral, and that is managed by the library. The user has no interrupt interface, and no interrupts are generated on each pulse. Interrupts arrive when the 16 bit counter buffer overflows, so this library has a tiny interrupt footprint while providing support for up to 10 simultaneous quadrature encoders.

## Pull Downs/Ups
To specify the weak pull resistor set the value [useInternalWeakPullResistors](https://madhephaestus.github.io/ESP32Encoder/classESP32Encoder.html#a53dc40c9de240e90a55b427b32da451f) with the enum types [UP, DOWN, or NONE](https://madhephaestus.github.io/ESP32Encoder/ESP32Encoder_8h.html#adca399663765c125d26e6f2896b5b349)
# A note on KY-040 and similar
The "switch style" encoder wheels used by breakout modules such as:
https://usa.banggood.com/KY-040-360-Degrees-Rotary-Encoder-Module-with-1516_5mm-Potentiometer-Rotary-Knob-Cap-for-Brick-Sensor-Switch-p-1677837.html
need electrical debouncing in the range of 0.1 - 2 uf per encoder line to ground. This device bounces much more than the PCNT hardware modules debouncing time limits. Be sure to [setFilter()](https://madhephaestus.github.io/ESP32Encoder/classESP32Encoder.html#ae3cecb7d572685b3195f8a13409b3390) to 1023 as well after attaching in order to get the maximum hardware debouncing.
