We’re pleased to highlight an article by Christopher R. Bowman from the latest edition of the FreeBSD Journal.
In “Building u-boot,” Christopher provides an overview of how the u-boot bootloader is built and maintained within the FreeBSD ecosystem.

10 years and a few days ago, I was running a DIY Synth workshop with STM32F7 dev boards in our kitchen in North London... Still have ~10 of these boards.
Here are also two videos (live performances) of some softsynths (some with MIDI via USB support) which we built in these workshops (I did quite a few of those in that year)...

I went looking for embedded software design patterns and I found this book that's online for free.

hey, people knowledgeable in #electronics , I have a dumb question:
I have a 16x16 panel of rgb leds (WS2812B ? not 100% sure, but 5v IN)
I want to pilot it with a RP Pico 2W.
If I have a beefy enough USB charger / battery, is it safe for everyone to use the usb plug of the RP Pico, and get the 5v Vin power for the panel from the Vbus pin of the RP pico? Will it provide safely the multiple amps the panel needs? (how much exactly? can't find) for full white light?

an e-ink PDA? I'm gonna try
[Edit: solved, needed to bump to 0.3.0]
Ok sorry #embedded #rust but I'm tired and I need your help.
I'm trying to add some irq stuff to my project, using https://github.com/rp-rs/rp-hal/blob/main/rp235x-hal-examples/src/bin/gpio_irq_example.rs as a template (for my rp pico 2w)
everything goes fine until the line:
hal::arch::interrupt_unmask(hal::pac::Interrupt::IO_IRQ_BANK0);
rustc tells me this function doesn't exists. I mut be missing an import or a feature, but I can't find which one. How do you troubleshoot that?
