Just wondering if anyone created any good example sketches using zephyr on a Teensy 4 or 4.1
docs.zephyrproject.org
I know there have been a few threads up here where questions were asked about using SPI or I2C, but I am not
sure where these projects ended up.
More or less all of my experiences with Zephyr is trying out and extending the Arduino wrappers for Zephyr for some of
the Arduino boards, such as the GIGA, Portenta H7 and Portenta C33. More details about setting this up can be found
on the Arduino Blog:
blog.arduino.cc
Or the Readme file on the github project: https://github.com/arduino/ArduinoCore-zephyr
But it might be fun to try developing some programs using zephyr directly on the Teensy 4.x boards. So far, I have mainly just run a few of
their example sketches like blink on the Teensy 4 and 4.1.
While I was playing with it, I created a new branch that adds support for the Teensy Micromod as well.

But it would be more interesting to have some more real level sketches, like list the files on SD card, or display something on a screen, ...

Introducing Arduino cores with ZephyrOS (beta): take your embedded development to the next level | Arduino Blog
Last July, when we announced the beginning of the transition from Mbed to Zephyr, we promised to release the first beta by the end of 2024. Today, we are excited to announce the first release of Arduino cores with ZephyrOS in beta! ZephyrOS is an open-source, real-time operating system (RTOS)...
