Right, now I’m worried… how did you know my Teensy 4s arrived yesterday? :laughing: :laughing: Great work Ivan [edit: and Valeros!] … look forward to being able to spin them up using PlatformIO! :slight_smile:

Happy coding with PlatformIO! :hugs:

There is a bad link, “mbed-rtos” in the docs.

Is there no rtos for this device, seems silly to have this kind of speed without a rtos.

The mbed-rtos example was removed back in October 2018, but mbed still appears to be supported and all the other examples are present, so perhaps it’s just a matter of looking at the other examples provided with mbed?

I’ve done a PR to remove that link:

Thanks, it has been just fixed!
