demo for publishing diagnostic status message

[patrickwasp]

Can we get a demo for publishing a diagnostic message with a key value sequence?

I'm not sure how to allocate, initialize, and assign diagnostic_msgs/msg/KeyValue[] values

Hello @patrickwasp, here you have documentation on how to init memory for types in micro-ROS: https://docs.vulcanexus.org/en/latest/rst/tutorials/micro/memory_management/memory_management.html#message-memory
