NAME

Device::Chip::ADC121Sx - chip driver for ADC121Sx family

SYNOPSIS

use Device::Chip::ADC121Sx;

my $chip = Device::Chip::ADC121Sx->new;
$chip->mount( Device::Chip::Adapter::...->new )->get;

printf "The reading is %d\n", $chip->read_adc->get;

DESCRIPTION

This Device::Chip subclass provides specific communications to a chip in the Texas Instruments ADC121Sx family, such as ADC121S021, ADC121S051 or ADC121S101.

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.

METHODS

The following methods documented with a trailing call to ->get return Future instances.

read_adc

$value = $chip->read_adc->get

Performs a conversion and returns the result as a plain unsigned 12-bit integer.

read_adc_ratio

$ratio = $chip->read_adc_ratio->get

Performs a conversion and returns the result as a floating-point number between 0 and 1.
