NAME
Device::Chip::MCP3221
- chip driver for MCP3221
SYNOPSIS
use
Future::AsyncAwait;
my
$chip
= Device::Chip::MCP3221->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 Microchip MCP3221 chip.
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.
MOUNT PARAMETERS
addr
The I²C address of the device. Can be specified in decimal, octal or hex with leading 0
or 0x
prefixes.
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.
