Want to configure your Ultimarc controller mappings at boot up? Use this tiny (<60MB) image to set your configuration from a Base64 encoded JSON environment variable.
Build with the Ultimarc-Linux library on top of Alpine Linux.
Incredibly easy to use, just set an environment variable called KEY_BINDINGS inside you Balena device and this
block will send it to you controller when it starts up.
To Base64 encode your configuration, use an online encoder like https://www.base64encoder.io/. Paste your controller
JSON configuration in, then copy the encoded value into the value of you KEY_BINDINGS environment variable.
If you need some default configuration mapping files for your controller, take a look in the Ultimarc Linux repository https://github.com/katie-snow/Ultimarc-linux/tree/master/src/umtool
