Description: "[A] new series focusing on how to build computers [from scratch] using simple electronic devices such as microcontrollers (MCU) and system-on-chips (SoCs) to achieve meaningful and concrete computing capabilities... [Y]ou will also be able to come up with your own computer designs, tailored around your computational needs."

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.

Dmitry is back again with another minimal computer. Last time he managed to boot #Linux on an #Intel4004¹. Now he wants to run #vi, #gcc, and #make, ends up doing it on a tiny #STM #microcontroller with a luxurious 32K of flash and 8K of RAM. The 4004-based machine took a *week* to boot, this one takes just a minute!

It's again made possible w/ #MIPS #emulation. The overclocked host CPU emulates a MIPS #R3000 at 1.65MHz with FPU disabled.

In my latest #Zephyr video, I demonstrate how to connect OpenOCD to GDB and perform step-through debugging. It takes a little bit of configuring, but the toolchain is worth it for #embedded #programming.

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.

Pretty interesting attempt at a minimal OS designed to run literally anywhere.

> Winter is coming and Collapse OS aims to soften the blow. It is a Forth (why Forth?) operating system and a collection of tools and documentation with a single purpose: preserve the ability to program microcontrollers through civilizational collapse.

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.
