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?

How about Rust for real-time applications?

I've been fixing a bunch of cmse/trustzone bugs in the rust compiler lately, and we now have an RFC that should prepare the way for stabilization:
https://github.com/rust-lang/rfcs/pull/3884
Trustzone isolates code and memory that deals with secrets from other code, so some buggy C library won't leak your sensitive data.

Working on BLE packet sniffing and transmission for MeshTNC, bc who doesn't want to do APRS or meshcore over BLE advertisements 😉
My quick hack feels promising so I think I'll clean this up and PR it.

This looks awesome! I love strongly typed scripting languages! 
And the fact that it integrates with Rust so seamlessly... ✨
