This Device::Chip subclass provides specific communication to a Texas Instruments DAC7571 attached to a computer via an I²C adapter.
The reader is presumed to be familiar with the general operation of this chip; the documentation here will not attempt to explain or define chip-specific concepts or features, only the use of this module to access them.
The I²C address of the device. Can be specified in decimal, octal or hex with leading
The following methods documented with a trailing call to
->get return Future instances.
$chip->write_dac( $dac, $powerdown )->get
Writes a new value for the DAC output and powerdown state.
$powerdown is optional and will default to
normal if not provided. Must be one of the following four values
