I don't suppose anyone here knows FOR SURE where SRAM4 ends up on the STM32U5[34]5 parts? Since those parts don't have SRAM3, I'm guessing that there is a hole, and it lands "somewhere". It is "special" in that it is the only memory DMA can talk to when the chip is asleep, but where is it? Hmmm?

All in all I felt season 1 of Murderbot was well done. It covered "All Systems Red" pretty well and I enjoyed the cast. As a huge fan of the books I was worried it would not translate to this format but feel like they did a good job. I find the calls to Apple to fund the development of season 1 of Sanctuary Moon hilarious 😆

TIL: --install-suggests together with 'apt install build-essential' is the sekrit code for "INSTALL EVERY FUCKING THING YOU CAN FIND" sigh.

I'm reminded once again to never ever ever use --install-suggests.

Finally finished the VSC8512 writeup! Ended up being just a biiiit longer than I had expected but there was a lot to talk about.

I still want to refactor my code a bit to be cleaner and more OO, what I have now is a bit quick-and-dirty, but it works.

Switch project, part 3 - what Microchip doesn't (officially) tell you about the VSC8512

Take a moment to parse that, right wing violence is reduced by prosecuting their leaders, they are the bulk of domestic terrorism. Gonna put NYT back on Trump's hit list.

Random question, has anyone reverse engineered the bluetooth protocol between the Canon IVY printer and the app? I'd like to print on mine without using templates (or the app).

I’ve been prescribed anti-gloating cream.

I can’t wait to rub it in.

This is the heartwarming moment we need right now:

11-year-old Danish kid Jens Fogh made Easter decorations and sold them, thereby raising USD 5300 which he used to buy 270 school backpacks for Ukrainian children. So while in Denmark, Zelenskyy presented him with a medal for his friendship.

A hero meets a hero — I love it! ♥️

I've had my eye on these #USB power meters for a while. They come in lots of variations, with different ports and screens, but my big concern is how they handle USB power negotiation with various #fastCharging protocols. Does anyone have any recommendations for which devices handle #USBPD, #SuperVooc, and #QuickCharge?
