Module analog_comparator

Source
Expand description

Provides userspace access to the analog comparators on a board.

§Usage

ⓘ

let ac_channels = static_init!(
    [&'static sam4l::acifc::AcChannel; 2],
    [
        &sam4l::acifc::CHANNEL_AC0,
        &sam4l::acifc::CHANNEL_AC1,
    ]
);
let analog_comparator = static_init!(
    capsules::analog_comparator::AnalogComparator<'static, sam4l::acifc::Acifc>,
    capsules::analog_comparator::AnalogComparator::new(&mut sam4l::acifc::ACIFC, ac_channels)
);
sam4l::acifc::ACIFC.set_client(analog_comparator);

§Number of Analog Comparators

The number of analog comparators available depends on the microcontroller/board used.

§Normal or Interrupt-based Comparison

For a normal comparison or an interrupt-based comparison, just one analog comparator is necessary.
