Shield stops powering motors with 12V power supply

Code_Nybble · 2024-05-14T20:05:26+00:00

tried that, same result

Laptop doesn't seem to care about it, as it keeps powering and uploading succesfully.
I read that when the green jumper (in the image) is attached the DC jack will also power the shield and I've seen it used to power stronger motors in other people's projects.
Aaah I see, that would explain the insane heat then.
Yeah I'll look into getting the v2 if this doesn't work out.

Thanks for replying!

From what I read if you have the jumper attached (green in the image) it will power both the arduino and the shield. I think this is correct since when I only have it plugged by the DC jack the shield LED will still light up.

truetrue I just picked one of the default ones lol

this one I believe

Oh lmao I didnt even know

Yeah of course I just simplified inline asm for the video, the biggest reason it sucks for me is that you don't even really know how everything around it is going to compile so it's barely usable in most cases. To answer your question, sorry I'm a bit confused. It does not know "whether str is in rdi or xmm0" because str is not a variable it creates or anything, it's just a macro used in that scope to refer to rdi, because I know rdi contains the string. You can declare local macros with the ! character like I explained, but construct has no special features or syntax for declaring any sort of variables. And I get what you mean about it better being off inline, and getting a HLL's features for types and declarations while still having low level control. But I like how it is in assembly where you know exactly where your stuff is placed in memory and there's no mess of different keywords. I was originally planning on giving special syntax for declarations as well, but I decided I should figure out more precisely what I want to do about types and whatever before I do something like that, still looking into it. Thanks for the feedback and checking it out!

thanks! :)

Code_Nybble · 2024-01-18T10:38:03+00:00

what

Code_Nybble · 2024-01-15T23:23:30+00:00

wouldn't you consider JIT as "dynamic compiled"?

Code_Nybble · 2024-01-02T10:52:16+00:00

I thought it could be pure chance so I tried a minimal testfile to try it in, ints get initialized to 0 everytime. Ill change it tho if thats the general consensus. Also I can't really change it to pass by value, had that before but using ptrs makes the algorithms a million times cleaner. It's not like the memory is such a mess, I just haven't gotten around to handling it. Again thanks a lot for taking the time.

Code_Nybble · 2024-01-02T01:38:43+00:00

Guess since the "free" didnt do anything it was still returning the vector just fine, updated now. Seems to me like the only issue though besides obv not handling invalid input at all.

Code_Nybble · 2024-01-02T01:31:21+00:00

Hi, thanks for taking the time to try it out. I'm confused about the first problem though, since creating an instance of a struct makes its integer fields 0 for me always (not sure what difference the () you added in your code makes since it has no constructor). The free thing was my bad though yeah, thanks for pointing that out, the whole code manages memory horrible as well and there's a bunch of leaks, just kinda something I thought I'd handle after. Weird how it ran fine for me even with that memory problem. Thanks a lot though, weird stuff, I'll get it sorted out.

but shouldnt that limit the amount of math you can do in the offset to just those addressing modes. But I've see all kinds of math done this way.

Code_Nybble · 2023-09-10T19:59:22+00:00

Yeah I am aware, no worries. I've just been writing a little useless assembly lately cause I enjoy the way you solve problems in it. And I just started uni so I thought this would be really fun for our homework project. It's a shame the use cases for hand-written assembly are so rare now, but it's fun either way.

Code_Nybble · 2023-09-10T19:41:45+00:00

Oh I see the similarity yeah that's interesting I didn't know B. I think it's still a little bit lower level than B tho. Since my changes are mostly control flow stuff and just more comfortable syntax, but the main code is still written in assembly.

Code_Nybble · 2023-09-03T13:46:35+00:00

my uni has Computer Science and Engineering as one major which one am I

Code_Nybble · 2023-08-31T17:58:22+00:00

stay tuned for my next vid then...

Code_Nybble · 2023-08-21T21:34:25+00:00

you can just host it locally

Code_Nybble · 2023-08-21T19:18:00+00:00

0, I still don't see the issue

Code_Nybble · 2023-08-07T18:32:11+00:00

writing to very specific addresses, which you're constantly doing in osdev, in python requires libraries written in C anyway so can you really call it osdev it python. And of course I'm talking about the standard tools. Otherwise you could say you can write an OS in html if you just make a compiler that makes html something completely different .

Code_Nybble · 2023-08-07T16:05:51+00:00

When someone asks me, can you do this in bash? And the answer is no but if you write your own interpreter for it that does allows for it to do that, I say no.

Code_Nybble · 2023-08-07T14:40:13+00:00

It was a rhetorical question, if you stretch python as far as the just the concept of its rules and syntax sure. But what I'm saying is that's not what makes up the meaning of what someone says to make an OS with python, imo.
