ooo looks like the #Zephyr SDK is getting caught up (mostly) on GCC and others. New version (in alpha) is GCC 14.3-based, which was released less than a month ago.

Just updated https://mov.im/blog/debacle/76bf90a4-5f59-4962-92db-6cd859f42ec9

If you're outgrowing Arduino or feel limited by bare-metal and FreeRTOS, #Zephyr might be your next step. It offers built-in drivers and cross-platform hardware abstraction, perfect for scalable, production-ready #embedded systems.

alright i am checking out #tmuxAI. i was a fan of gnu screen(1) in the 90s and early aughts, used it all the time, but my openbsd friends rapidly all adopted #tmux and i joined them.

originally i learned screen just cuz i wanted a way to leave myself on #irc & #zephyr when i was away from a terminal.

anyway this #AI assistant for tmux is seemingly able to operate in sessions, panes, and windows!

if you're really curious about this too it's in #macOS #homebrew today:

Thursday...and that means a new #Zephyr video I cover using LCD drivers and LVGL to make basic GUIs. Check it out!

It's taken a while, but I think I've finally gotten the hang of some of the #Zephyr project/workspace patterns, specifically manifests and "shared libraries”.

OK, somehow this code now blocks forever... what? It should just wait until you connect to the serial console. #zephyr

```c
while (!dtr) {
uart_line_ctrl_get(dev, UART_LINE_CTRL_DTR, &dtr);
k_sleep(K_MSEC(250));
}
```

New #Zephyr video! One big benefit of using an #RTOS is the ability to run multiple threads, and that's exactly what I cover. Check out the full video!

Happening next week! Sign up for my #Zephyr workshop at 10:30 am CDT April 24. I'll cover the basics of writing a cross-platform #embedded device driver. If you want to follow along, consider getting the parts now.

Oooo #zephyr doesn't want to compile with the GCC 14.2 build... so many -Wincompatible-pointer-types warnings... so many.

Am I wanting to stab the computer while trying to deal with debugging threads and #zephyr? Yes. I'm gonna have to go get my JLink debugger.

Version 1.1.0 of CANnectivity, an #OpenSource USB to CAN adapter firmware based on @zephyr, is now available!

This release is based on the just released #Zephyr v4.1.0 and brings, among other things, explicit support for a number of popular USB to CAN adapter boards.

More details available in the #CANnectivity v1.1.0 release notes: https://github.com/CANnectivity/cannectivity/releases/tag/v1.1.0

Dare I tippytoe back into Rust on #zephyr? Maybe.

A small victory, but a significant one. A perfect illustration of the importance of State/Local politics as a bulwark of resistance against federal overreach. An inspiring example of parrhesia, speaking Truth to Power.

Updated a few projects to #Zephyr 4.1 from 4.0, and so far no major concerns. I did trip over a devicetree thing where, I think, some things got changes from properties to strings. OK, that's just a weird choice. I need to go read the commits to understand why.

Here is the one everyone has been asking for: Introduction to #Zephyr The first episode is out! My plan is to get #embedded devs up to speed on this fast-growing #RTOS. Check it out!
