Pedal.h class handles smoothing, mapping, calibration etc, but does not implement HID. This means you can use the class to direct the data elsewhere (maybe wireless, bluetooth etc.)

Each Pedal is initialised with a supported hardware type (ADS, analogRead or HX711), with a reference to each type being used when reading the pedal value. This may change in the future to remove hardware implementation, since there are many other ways of handling pedal data (hall effect sensors, potentiometers, other ADC modules etc) that may use different range, scalings, conversions. All raw pedal data should be provided as a 16-bit number (0-65535) for standardisation with HID axis'.

Methods are available to set calibration data such as deadzone, range, filter, mapping values etc. You may wish to implement a command based serial protocol to handle setup from software (see Simforge_Engineering_Pedals.ino). You can also implement auto-ranging calibration, percentage based deadzones and other features in your implementation.
