NAME
Device::Chip::ADC121Sx
- chip driver for ADC121Sx family
SYNOPSIS
use Device::Chip::ADC121Sx;
use Future::AsyncAwait;
my $chip = Device::Chip::ADC121Sx->new;
await $chip->mount( Device::Chip::Adapter::...->new );
printf "The reading is %d\n", await $chip->read_adc;
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 in an await
expression return Future instances.
read_adc
$value = await $chip->read_adc;
Performs a conversion and returns the result as a plain unsigned 12-bit integer.
read_adc_ratio
$ratio = await $chip->read_adc_ratio;
Performs a conversion and returns the result as a floating-point number between 0 and 1.
