NAME

irlink - Infrared remote controller

DESCRIPTION

The irlink class communicates with a Circuit Cellar IR- LINK transmitter/receiver. The idea behind the irlink class is to use a trainable handheld IR remote controller like the one you might already be using with your TV set and have it contain 10 or 20 of the 512 possible codes. When the keys/codes are sent, they cause specific LYMB actions to be executed.

This example creates an action and then specifies a remote control key that will execute this action. When the ON button on the remote control is pressed, a tick! will be sent to the some_action action. The irinit script defines

standard remote controller keys.

actions new: some_action

tick_actions = 'some_action print!;' ; irlink new: ir
