Universe metadata
Universe metadata¶
CRMX transmitters may transmit some universe metadata information used to identify the received universe on the receiver side. These are;
- Universe name: A 16 character string with a human readable name identifying the universe.
- Universe color: RGB code for an LED that can easily be used to visually identify the universe by color.
Universe Name¶
The universe name is an up to 16 characters long textual name of the CRMX universe.
When operating in RX mode, this information is available by reading the universe
name register.
In TX mode the first 16 characters of the DEVICE_NAME will be used. Device name
can be set either via SPI or from the CRMX Toolbox app.
Universe color¶
The universe color is a help in identifying what receivers are linked to a particular one transmitter. By selecting a color at the transmitter, either by configuring it via SPI or through the CRMX Toolbox app, this color code is automatically distributed to all linked receivers.
To indicate this color code, an RGB LED can be connected through a RGB LED driver as shown in the LED outputs section. It os also possible to read this data from the SPI interface to show in a menu system or similar.
When operatig with transmitters that does not support universe color the color will be set to green.
