Will there be time to introduce the following topics at the next WG? @hsgwa of ISP (Tier4’s subcontractor) will explain the topic if possible.

Hi @takuya.azumi thanks for nominating the topic. I just had to cancel the meeting on June 9.

@razr will put your topic on the agenda for the meeting on June 23.

Thx, D.

@Dejan_Pangercic No problem. Our topic is not urgent. We will attend the meeting on June 23.

Thank you for putting our topic to the next RTWG agenda.

I’ll talk a summary of the following posts.

This post is related to today’s topic.

I won’t describe this topic today, but any comments on this topic are also welcome.

@razr Thank you for your help.

Hi @hsgwa @takuya.azumi: Would it make sense to introduce the other Discourse post (Threaded Callback with priority, affinity and overrun handler) in one of our upcoming ROS2-RT calls as well? cc @Dejan_Pangercic @razr

Thank you for suggesting our post.
This post is relevant in real-time as well.
If I can have time at the WG, I’ll explain a summary of the post and intention to implement a Threaded Callback.
