I have a #microcontroller which specifies a 32.768 KHz #oscillator for the RTC.

I have a 12KHz oscillator.

I want to make the #PCB NOW.

What if I use the 12KHz instead? Can I expect glitches?

Why would the recommended spec even be so inflexible? Is that because of some time-dpendent internal circuitry?

Making progress with embedded #Rust! I’ve got I2C and USB serial working now on my #RaspberryPiPico. The Pico HAL works pretty well, once you get used to it. #embedded #microcontroller #programming #rp2040

Want to move beyond #Arduino on the ESP32? My latest tutorial shows how to set up ESP-IDF with Docker, build a blinky app, and flash it to hardware. Also: emulate it in #QEMU!

Going to give my talk about programming microcontrollers without using any SDKs or whatever in about 6 hours at #WHY2025! If you're not here, you can watch the livestream:
https://streaming.media.ccc.de/why2025/cassiopeia

(The talk should also get uploaded very soon after I finished, so no need to rush).

I know I poke fun at the evangelism, but I’m finally taking the plunge to learn #Rust. It’s broken the TIOBE top 20 list (https://www.tiobe.com/tiobe-index/), and I’m starting to see some adoption in the #microcontroller world. I really like Brown’s interactive version of “The Book” - https://rust-book.cs.brown.edu

I'm excited to announce my new course! "IoT Firmware Development with ESP32 and ESP-IDF" is designed to take you beyond Arduino to building professional #IoT devices with #WiFi, HTTP/HTTPS, MQTT, and SSL/TLS.

Our second episode of #DayGlowShow streams live July 10 at noon Pacific (tomorrow / 7pm UTC)!

@ishotjr and I are digging into the #PicoCalc – a #microcontroller development platform based on the #RaspberryPi Pico. Plus, reflections from #Teardown2025

Hey! You! #microcontroller and #electronics nerds of the fediverse! Can anyone help me find the schema files for Microship's Atmel Tools Device Files?

The final #Zephyr episode is out today! Zephyr works with "boards" and creating a custom board definition can be a pain. But I've got you covered! Check out the full video to learn more

Getting #WiFi to work in #Zephyr can be a bit tricky...so, I'm here to help! In my latest video, I show how to configure a WiFi driver for the #ESP32 and make simple HTTP requests. Check it out!

Did somebody successfully hook up a #MicroController to react on the extra buttons on a #Shimano #DI2 setup?

I did not find good information about bluetooth/#ANT signals.

For example i want to build turn/brake signal lights or something.
