I2C Slave Mode

Are there plans to implement I2C Slave mode for ENDPOINT devices?

Can you explain where world a slave be useful please?

I use teensy 4s to interface with sensors and controls (because the drivers are already written.) But I can’t use teensys as I2C slaves and masters at the same time, and I want to link them to other microcontroller boards for data packet exchanges.
I’ve been using TinyCLR devices wherever the code gets complex, because I find C# code more maintainable. In particular, I’ve been using FEZ Portals as slave robot controller displays, and FEZ Sticks as slave robot brains.

Sounds to me like endpoint should be the master in this case. It is usually easier to keep the master in the larger system.

We can still look into adding slave support in the future.
