* @brief Infrared remote library.
|
|
*
|
|
* An infrared remote contains zero or more infrared signals which
|
|
* have a (possibly non-unique) name each.
|
|
*
|
|
* The current implementation does load only the names into the memory,
|
|
* while the signals themselves are loaded on-demand one by one. In theory,
|
|
* this should allow for quite large remotes with relatively bulky signals.
