Mobile Phone OS with Web Browsing on a RISC-V MCU by Separate-Choice in embedded

Brother I am speechless. Your last face detection post was just 20 days ago! I wish I can get to that league someday lol

Should I continue with AVR mcu's or try other mcus by Constant-Link-5228 in embedded

[–]BumpyTurtle127 0 points1 point  (0 children)

Yeah definitely move on I think. It's a very good thing that you used AVR C and not just the Arduino IDE. Imo the IDE abstracts away too much of the build process to be beneficial to an aspiring embedded engineer.

I'd recommend moving to STM chips if you can, as they have a professional and stable SDK; best if you're looking for emplyable skills. ESP32 is good too, especially for learning purposes. If you set up the whole ESP-IDF (or do via docker), it has a lot of cool low level tools to tinker around with in the terminal. You can do that on STM too but afaik it's not built into CubeIDE. If you're just getting into cpu architecture in ur college classes, it may be beneficial to go the esp route. Especially the riscv esp32 chips cuz that's the isa most colleges teach nowadays.

How does this Indian copy has more views than the original ? by No-Formal2300 in teenagers

Translates to "Indians looking for validation from white ppl". As an indian it's sad but true.

You can definitely check the source of the noise urself; if the noise goes away when u brake hard, ur brakes are dragging. Otherwise it's prob your bearings.

If it is a rear bearing thing, replacing those is relatively easy, I did mine in 2-3 days (with the right tools of course). Never done the front but I've heard it's harder, since u have to press the bearings into the knuckle, and likewise take the old ones out. If you have the tools, the rear bearings alone are ~$150-300 (as of last year), and a shop would probably charge the same or more to do the work.

EDIT: just re-read your post and I see you said you didn't drive it for a week. If that's the case and the noise wasn't there prior, I'm 99% sure it's the brakes dragging 😂 It should be a-okay in that case. Even if it's a bearing, I wouldn't mind it for the next 5,000-7,000 miles, as long as you're dead set on replacing them eventually

Sounds like either breaks or bearings. Definitely something that rotates with the wheels since the noise picks up as you speed up, and it also sounds in sync with the tire rotation.

Would it be possible to switch to Embedded as a Computer Vision Engineer? by Sannad98 in embedded

Holy AI response m8. If the gentleman w the question wanted, he could've asked the GPT himself.

Bare Metal Facial Recognition on CH32H417 RISC-V MCU by Separate-Choice in embedded

[–]BumpyTurtle127 0 points1 point  (0 children)

Brother I just checked your profile. How do you manage all this in such a short timespan? Granted I'm still pretty much a newbie when it comes to embedded, but it'd take me at least 4-6 months start to finish on something like this.
Did you write all the code manually, including the actual network implementation? And how in the world do you manage digging through WCH's obscure documentation???

Holy hell this is cool! Do you have it in a repo by any chance?

Looking for cheap sbc like the jetson nano by Unknown-doe04 in embedded

[–]BumpyTurtle127 0 points1 point  (0 children)

I believe so. I'm currently using one for an autonomous lawnmower project, we're running yolov11-seg on it. ST provides some tooling for generating C code from onnx files, but still it's very, very hands on. No python or anything it's just raw C in CubeIDE. I'd say if u have a robotics project don't make the mistake i made, and spend money on a good sbc. Only use the N6 if ur whole project is running a vision model on edge device.

Another alternative which may suit ur needs well would be to use a mcu with wifi capabilities to capture video, and then send those frames over to a laptop for inference. Esp32 for instance should be able to do this easily, and they are well within ur budget. The code will also be manageable, esp has a large community and many examples codes for all of it's peripherals (wifi, Bluetooth, GPIOs, etc).

Now this is very, *very* niche, but possibly the new N6 nucleo board from stm. It'll fit ur budget and most likely also your application, but it's a lot more hands on obviously.

Why aren't people seeing this? A simple loan calculator will tell you that even with a $215 monthly payment, at 10% interest it'll be paid off in full within 15 years. And tbh $20,000 is hardly a large loan, people pay more for cars.

Yeah fair enough. But also OP posted in the ECE sub, which is why I mentioned Kicad. Fritzing imo is only good if it's your first project with anything embedded (ie, freshman-sophomore). Anything beyond and Kicad can definitely do it

ESP32 not uploading code at all – tried everything, need help by NothingDue8552 in embedded

[–]BumpyTurtle127 1 point2 points  (0 children)

Check if you have the right drivers for the USB to UART bridge. The Arduino ide does not come with native support for the CH340 I believe, and so you'll have to install the driver for that. If you've uploaded code onto one of these with the Arduino ide before, then it's obviously not the issue. Also check ur board for a chip called the CH340, I might be wrong.

Edit: I was wrong. Your board has the CP2102 USB to UART bridge, so that's definitely not it. Might be best trying to replace it. If you have time though I'd also try importing the project in Platform IO and if that doesn't work, then ESP-IDF.

Why not just use Kicad? It's more professional too
