Touchscreen

The Touchscreen interface module controls and maintains the logical state for a touchscreen device such as a Crestron touchpanel or Apple iPad/iPhone.

Summary

Exactly one Touchscreen module is associated with exactly one Crestron App instance. This module manages the current users selections such as room and source. Many of the signals on the Touchscreen module are directly linked to smart graphics button presses. This is done dynamically through the ID-switching and cross-point routing systems built into the Crescendo framework so that subpage reference lists (such as watch or listen lists) populate dynamically based on current user selections.

The Touchscreen interface module acts almost like an EIC between the Crestron App instance and the program, receiving user button presses as input and outputting the button press feedback.

It is through Touchscreen interface module that the crescendo program framework receives instruction to make and break crosspoint connections and drive dynamic lists, all as a result of user interface button presses.

Tutorial

Parameters

Configure the Name and ID parameters. The Touchscreen name can be anything. The Touchscreen ID should use a two-digit, zero-padded number between 1 and 99 (01 or 99). Default Room accepts the same type of parameter as does ID and the two-digit, zero-padded number between 1 and 99 that it receives should be the ID given to the Room model in which the physical iPad/iPhone/Crestron touchpanel associated to this logical Touchscreen interface model will most often reside or to which it will be assigned.

App URL 1 through 5 parameters denote the apps to be launched in the case that this Touchscreen interface module instance is associated to a physical iPad. Example formatting for App URL 1 and 2, respectively: music:// (move cursor down to next parameter) sonos://

Inputs and Outputs

Complete documentation on interface signal joins can be found in the Join Standard. 

Notes

Through the "[App_URL$]" and "[Open_App]" signal slots, the Touchscreen module handles the program's awareness that the Crestron app has been launched. This interface module also handles configurations information for having the iPad open other apps (such as the app for a third party security or climate control system) through the signals "[Open_App_01]" through "[Open_App_05]," so up to 5 apps can be linked for launching (and when launched a button in the top left will allow the user to effortlessly navigate back to the Crestron app).
