Okay, what product manager came up with this:

'256-Mbit Hexadeca‑SPI PSRAM '

Just call it what it is, 16 bit parallel interface with in-band control signaling.

This week, Chris( @stoneymonster ) and Elecia( @logicalelegance ) spoke with Janet Hansen( @flashingjanet ) about the world of professional costumery (with electronics) and becoming an artist.

Excited to be talking about #embedded #rust and #osdev at the virtual Rust & C++ Dragons meetup!

Come say hi it will be a chill event!

#intro

Hi! I'm an austrian hobby musician, as well as a nature and (cautious) tech nerd. In general I don't like boxes for my #music (active and passive) or any of my other passions and I seek the overlap. I play many instruments, sing and do beatboxing. I also like #drawing.
I work as #embedded dev and also do some #DevOps stuff. I don't have CS background, but I try to have an architect's view on software dev and keep up-to-date with new #programming tech and best pratices.

I wrote about a project I did for my kid a few weeks ago: he found using a regular die for dice chess inconvenient, so I replaced it with an ESP32 and some Python code.

I made a start on my 30-key keymap. I think the options in vial seem very limiting at first glance but it is also very possible I don’t really understand the power I might get from it #SplitMechanicalKeyboard

More and more I just wish that the keyboards could know what program is active to give context sensitive layouts.

I think this idea comes from being very used to vi/vim style modal editing. I don’t need my keys to be alphas in the most cases. I’m happy switching to inputting characters in a separate mode so I want to design my keymap like that.

If the OS could be more expressive in telling the keyboard what modal state to be in that could also be really interesting.

This week, Elecia( @logicalelegance ) and Chris( @stoneymonster ) host Kwabena Agyeman, CEO of OpenMV. They chat about more powerful (and smaller!) programmable cameras.

The transcript( https://embedded.fm/transcripts/497) from the show is available now!

#introduction I'm (still) recovering from Bad Stuff(tm) and looking for some new perspectives, so there's not a lot to introduce beside my past, which is my own. If we have interacted previously, you are welcome to follow in any case! Formally #embedded software engineer, open spaces and open networks enthusiast, might end up driving trains. I'm sparingly into local activism, have support needs, and provide mutual aid. My personal tech stack is a mess and my personal projects are all on hiatus.

Many people are trying out #embedded development on RIOT at our booth on Chemnitzer Linuxtage. The awards for the embedded challenge are already gone, but you may find getting a first taste of playing with microcontrollers just as rewarding

This has been brought to my attention

Haskell for FPGA Hardware Design: Use abstractions like monads and lenses to implement 1970's retro-computing devices like arcade machines and home computers.

TinyGo 0.37 is released! That was fast, especially with all the excellent work that made it in:
- updated WASI support with latest from the Bytecode Alliance
- faster speed+PIO support on RP2350
- new Linux GC

Plus critical fixes too!

Full changelog: https://github.com/tinygo-org/tinygo/releases/tag/v0.37.0

#ReverseEngineering / #embedded folx, is it possible that a boot ROM is mapped near the end of the address space such that some of its contents wrap around?
See: https://github.com/NationalSecurityAgency/ghidra/issues/7917
Context: I'm trying to figure out the memory map for the #PocketViewer .

FUCKING A!

I have a #Rust programme on my #RaspberryPi #PicoW that reads data (an u16) from a sensor and you can then get that data from a web request. HUGE ACHIEVEMENT.

It has taken me like… a large chunk of three days… To get to this point from having code that reads the sensor and serves web requests. I feel like a moron. But hey, I've only been coding Rust for ~5 days. Probably taking the hard path by going straight into embedded with no::std…

It has taken so many attempts to get to grips with scopes, mutables, Rust's bloody intense syntax, etc, etc… but in the end I've worked out a way to pass a u16 to both spawned workers via some sort of a Mutex. I think I might have an extra level of indirection I don't need… but fuck it, I'll take that I can do this at all as a win.

Now I can take it outside (i.e. not USB-tethered) and see what it reads as an outdoor CO2 PPM measurement.

(I could have had this working in C++ in… minutes, but no, I'm a masochist.)

WDC sells the W65C02SXB single board computer with a brand new 6502 CPU and a bunch of support chips, at a very reasonable price, for people who want to learn about 6502 programming. Unfortunately, according to the documentation on the website, actually using this thing requires their proprietary Windows IDE to assemble your source code and flash the device.

Is that actually true? Has anyone else bought one of these and developed for it under Linux? I'm hoping for something like "assemble your code, producing something like a ROM image, flash it to the device, hit the reset button, watch the light blink".

Kann mir mal einer Erklären warum bei song.link das Einbetten von YouTube Videos geht und auf anderen Plattformen nicht?

Früher hatten wir ja die Möglichkeit die Videos von YouTube embedded anzuschauen, was ja auf Betreiben von YouTube nicht mehr funktioniert. Allerdings frage ich mich dann warum es bei song.link noch funktioniert. Ich vermute dort hat man einen entsprechenden Vertrag mit YouTube/Google abgeschlossen. Hier mal ein Beispiel:
