Prontohex

A signal-definition consists of two types of properties; signal encoding properties and radio configuration properties. The first part specifies the characteristics of the data encoding of a signal whereas the radio part specifies the required radio configuration to receive the signal. This section discusses the signal encoding properties of the Prontohex Signal Definitions.

Properties

The table below shows the encoding properties in the Prontohex signal definition.

Commands

Sometimes, devices have a static set of commands and do not include any dynamic data such as an address. This is the case for most infrared devices. In these cases, the cmds attribute can be used to predefine all commands. This property consists of an object that maps commands (specified as identifier string) to a prontohex payload (specified as String). The carrier in the prontohex String overrides the carrier in the signal radio specification.
