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!

Tomorrow is the day! Come hang out and learn about writing device drivers in #Zephyr. Even if you don't have hardware, you can still follow along. And yes, the webinar will be recorded.

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.

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!

Hey, #programming #electronics #arduino #microcontroller folks. Say I have a device like a joystick which generates its own data and clock signals, and I want a Pi Pico 2 to capture inputs from it.

What should the flow of that program look like? Do I just capture 2x the length of a full packet, find the single whole packet in it, read that and move on? How would you go about detecting and reading every individual packet?

Boosts and all comments welcome.

It's Thursday, and that means another #Zephyr video! I dive more into the Devicetree and how bindings files work to connect driver code. There's even a challenge at the end to test your skills. Check it out!

Looking for something "fun" to do this weekend? I might recommend learning about Devicetree on #Zephyr! In the latest Zephyr video, I cover the basics of Devicetree syntax and writing overlay files.

#TexasInstruments just released a #microcontroller so small you could lose it in your pocket. The #MSPM0C1104 is only 1.38 mm², smaller than a grain of rice, but still acts as a tiny computer. It has a 32-bit processor running at 24 MHz, with 1KB of memory and 16KB of storage. It can even sense things like temperature or movement. Power use is minimal, running on just 87μA per MHz and dropping to 5μA in standby. This makes it ideal for tiny devices that need to last a long time on small batteries. It is also built to handle extreme conditions, working in temperatures from –40°C to 125°C. https://www.ti.com/product/MSPM0C1104

I just backed this project on Kickstarter: https://www.kickstarter.com/projects/openmv/openmv-n6-and-ae3-low-power-python-programmable-ai-cameras

OpenMV LLC makes some incredibly powerful, small-form-factor #IoT cameras perfect for tinkering, prototyping, and making slick projects. I taught my Computer Vision with #AI course using their cameras. I'm excited about this new series: full object detection for a few mW. #EdgeAI #ComputerVision #Arduino #MicroPython #embedded #microcontroller
