NAME Device::Chip::MAX44009 - chip driver for MAX44009 SYNOPSIS use Device::Chip::MAX44009; use Future::AsyncAwait; my $chip = Device::Chip::MAX44009->new; await $chip->mount( Device::Chip::Adapter::...->new ); await $chip->power(1); sleep 1; # Wait for one integration cycle printf "Current ambient light level is %.2f lux\n", scalar await $chip->read_lux; DESCRIPTION This Device::Chip subclass provides specific communication to a Maxim Integrated MAX44009 ambient light sensor 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. read_config $config = await $chip->read_config Returns a HASH reference containing the chip config, using fields named from the data sheet. CONT => bool MANUAL => bool CDR => bool TIM => 800 | 400 | 200 | 100 | 50 | 25 | 12.5 | 6.25 change_config await $chip->change_config( %changes ) Writes updates to the configuration registers. Note that these two methods use a cache of configuration bytes to make subsequent modifications more efficient. read_lux $lux = await $chip->read_lux Reads the latest light level conversion value and returns the value in Lux.
