OpenC3 COSMOS 5.6.0 - Modern, Production Ready, Command and Control
Welcome to OpenC3 COSMOS 5.6.0!
This release brings some great new features, and also includes some important bug fixes. Everyone is encouraged to upgrade.
Important Migration Note
TlmViewer widgets had to be updated to support opening screens from ScriptRunner which caused a breaking change for any plugins containing a custom widget. Plugins with a custom widget will need to update their package.json file to use @openc3/tool-common version 5.6.0 (or later), and be rebuilt/reinstalled.
Open Telemetry Screens in Script Runner
You can now open telemetry screens in ScriptRunner! Either existing screens or using the local_screen feature you can define a unique screen right from your script.
display_screen("INST", "ADCS") wait(3) clear_screen("INST", "ADCS") wait(3) display_screen("INST", "IMAGE") wait(3) clear_all_screens() wait(3) definition = ' SCREEN AUTO AUTO 1.0 VERTICALBOX "Test Screen" LABELVALUE INST HEALTH_STATUS TEMP1 LABELVALUE INST HEALTH_STATUS RECEIVED_TIMEFORMATTED WITH_UNITS 30 END ' local_screen("TEST", definition)
Our plugin generators now support custom widgets. Run with:
openc3.sh cli generate widget MyWidget
Diff plugin.txt on Plugin Upgrades
Now if you upgrade a plugin and the plugin.txt file was changed, you will be presented with a diff interface that shows the changes and allows you to pick which lines you want to keep.
Install Plugins and Gems from the command line
The openc3cli command has been updated to support loading plugins and gems from your host machine. You can use like follows:
gem install openc3 openc3cli load /path/to/myplugin.gem openc3cli unload myplugin.gem__12345667 openc3cli geminstall my.gem openc3cli gemuninstall my.gem
log_message parameter added to cmd() apis
cmd() can now take an optional keyword argument called log_message that allows you to optionally not have a command be printed into the log messages. This is useful if you are frequently sending a command or at a high rate, and don’t want to spam the log messages. Note: All commands are always logged to our packet logs.
TlmGrapher Show Limits Updated
TlmGrapher Show Limits has been updated to color in the background for each section of limits. This makes the limits ranges much easier to see.
We now ship code to perform CRC8 calculations, on top of our existing CRC16, CRC32, and CRC64 functionality.
