Analog Endpoint

Interface to analog entities on BrainStem modules.

Analog entities may be configured as a input or output depending on hardware capabilities.

Some modules are capable of providing actual voltage readings, while other simply return the raw analog-to-digital converter (ADC) output value.

The resolution of the voltage or number of useful bits is also hardware dependent.

See the Analog Entity for generic information.
