RemoteSign: {CH} command

Declares a channel that is to be available on the remote device.

Each channel that is present will be reported in its own {CH} command.

Syntax

{CH}ch ␑ type ␑ p1 ␑ p2 ␑ name ␑ pins

A = Audio

For type OLED, rows
For type S, the number of sensors available

name a name of the channel (often provided by the {DCH} command)
pins - for RemoteSign ESP devices, a list of pins that the channel uses.

Note: To enable backward compatibility, traditional RemoteSigns and OLED signs must report their screen on channel 1. (So if Channel 1 is not type R it is not a traditional RemoteSign Windows.) Conversely all RemoteSign screen commands are regarded as being for channel 1.
