Over the past few episodes, we’ve been building up to this moment: writing device drivers. It’s tricky and takes a solid understanding of CMake, Kconfig, and the Devicetree. But here it is: how to write device drivers in #Zephyr!

#rtos notes
RM is easy. Rate monotonic. Highest frequency task, highest priority.
EDF is challenging. Earliest Deadline First, otherwise known as what I always do in academia.
LLF is really hard since you need to know remaining task time. Least Laxity First, or irl Least Likely to Fucking work
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!

Unraveling the Mystery of the Missing Commit Hash in Apache NuttX: A Deep Dive into RTOS Debugging
An elusive bug in the Apache NuttX RTOS has revealed deeper issues with static variables and the uname command. Join us as we dissect the intricacies of this embedded system and uncover the lessons le...
Hi @lupyuen !
I've been following you for a while and I am impressed by your work on Apache NuttX.
Currently I'm trying to get a LoRa project done - with a module that combines Raspberry's RP2040 ("Pico") micro controller and the popular Semtech SX1262 LoRa chip. RAKWireless offers this as the RAK11300 LPWAN module.
Now that I'm hooked with the NuttX project, I'm considering using it for this project.
To make it work, proper "sleep" support is required. Do you know if / how well sleep mode or dormant mode are supported on the RP2040 with NuttX? How can I find out online?

In case you missed my #zephyr workshop at #Hackaday #Supercon this weekend, the tutorial is available here: https://github.com/ShawnHymel/workshop-zephyr-device-driver
You just need an #ESP32 and an MCP9808 board—you can do the entire workshop at your own pace!
