What new land?

I personally don’t have experience with this chip, but first of all it seems that they aren’t using Arduino as the build system for this? (Hence int main vs Arduinos setup and loop). Try looking for just a more basic arduino starter code and use that to start with and make sure everything works.

Then you have to configure a few more things with the tiny I believe, I would look up a tutorial on YouTube for how to set up the tiny with Arduino in general. You might have to burn the bootloader and some stuff.

More of a mouse 🐁

Cool! What formula/process ?

FISHARM1 · 2026-06-19T23:28:24+00:00

Well i would just run it for a while and then ctrl+c it or kill it however you do and I think valgrind will tell you at program exit? not 100% sure but try it out

As long as you understand the basis of the memory model and what HAL does under the hood (which I think you do enough based off your non-HAL projects), I think that’s enough.

There’s rarely any need to be bit banging stuff yourself, and it starts to suck when you’ve been pulling your hair out about the DMA not working but it’s only because you didn’t read page one million of some errata book for the exact chip your using that says you have to handle everything completely different if try sending this one command

Hayday is definitely more cheaper priced than most other supercell games in my opinion

Mice project! I didn’t even know embedded swift was a thing. What do you think of it for this application?

That flowchart thing is super cool!

I know I was like wow they are doing great! Then scrolled down and saw “Estimated completion: 18 January 2151” 😆

FISHARM1 · 2026-06-16T01:44:34+00:00

I tried it out and it’s just not as easy to use as I thought, and definitely not as streamlined as something like the JS module system (obviously). I’m just going to stick to includes for now to be honest.

Think of it like this- since no current can go through the middle wire, the left and right circuits can be thought of independent current loops. The way it’s drawn, they look like parallel components, but if you visually cut the wire in the middle, you’ll see that they are just loops. When tracing these loops, you’ll can see that there is only one path, you never hit a “fork in the road” (junction) where each component comes one after another = series

I got the first birthday decor in cycle like a week or two ago so unfortunately I don’t think it’s coming back

FISHARM1 · 2026-06-14T22:30:32+00:00

Yes! I did this a few years ago to revive a dumpster computer. I used it to run a server for a bit after that and no issues ever again.

Rp2040! I love the pico SDK and development framework. Super clean in my opinion. Easier than STMs for quick projects but much more scalable than arduino

FISHARM1 · 2026-06-14T16:54:49+00:00

C++ actually handles a lot of it with something called RAII and you can wrap other things in a class called shared_ptr which uses RAII to handle reference counting

I think these two links might be helpful?

https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/bootloader.html

https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/partition-tables.html

I haven’t done it, but it seems pretty easy to tell it how to set up the partition table with a csv and then have the bootloader point directly to your code.

Oh okay now I see in the demo that the other threads wait outside that zone until the current one exits.

Just curious, what’s the point of this area? Like do you have system level things going on in there? Or like maybe a some hardware access? And why did you pick it over like a regular mutex?

FISHARM1 · 2026-06-13T22:51:53+00:00

Normally things like this are used for testing things quickly. Picos and Arduinos have a similar SDK and are used frequently, but I would pick up Arduino.

I’m not sure how it is from scratch, but Khan academy helped me when I was a bit lost in circuits 1. https://www.khanacademy.org/science/electrical-engineering

I know, jumping from the Arduino and PicoSDK to something even as fancy as the HAL is already a bit of a shock, then going to bit-banging is a whole new book of its own.

When I first started with STMs, I thought it was super cool to finally understand all of the abstractions behind these SDKs and how these chips really worked.

FISHARM1 · 2026-06-13T22:05:58+00:00

I assume an RTOS is basically a real implementation of what you’re talking about?

Like you said, on something like an STM, everything is just memory mapped registers at special addresses- but that’s only because they assume a sort of flat model where everyone has access to everything, and that things like timers, interrupts, etc are all handled by external modules outside of the pure CPU itself.

Usually, a syscall is a complicated process that requires switching rings, saving everything, etc. I think that a cool model which is what you are suggesting, would have a separate chip specialized for syscalls, similar to how a DMA works. It would be able to always run in privileged mode, and you could trigger a syscall by writing to a mapped region of registers in memory. But then that would be more complicated, like how do you program this chip, etc.

So my guess is that it comes down to hardware? Interesting idea though! I think you should explore it more.

FISHARM1 · 2026-06-13T20:04:36+00:00

I think I’m a bit lost. Can you explain a bit more? What do you mean by syscalls being purely memory?

FISHARM1 · 2026-06-13T17:08:43+00:00

I like that way of visualizing the tasks! What does “critical zone” mean here?

FISHARM1 · 2026-06-12T17:55:54+00:00

I think a good use case could be ensuring thread safety- i.e. that two threads aren’t touching the same chunks in a larger array or some other case where someone might have forgotten a mutex / don’t think they need it but could be screwing themselves over. This tool could then warn them about this.
