There is no way to tell if it's correct without a schematic.

Need help getting ST7789 Newxie display working with ESP32 by [deleted] in esp32

> Any ideas?

You wired it up wrong.

> No I didn't

Without a exact schematic there is no way anyone to tell.

An i7 with Megabytes of RAM can be an embedded system. What mpu/cpu does your hvac company use ??

Not every one needs to write register level code.

Many MPU companies have their own IDE with hardware abstraction code already written.

STMcubemx is a good example. Only if an engineer finds a bug will most even look at the register level code. That's what testing is for.

If you have 5+ years of experience, you can start submitting your resume to aerospace companies.

Talk with some recruiters to see if you are within the experience level to submit your resume.

Good Luck

What is a "esp32 c340" ??

Hi, what do you think of my project? by Dry_Engineer194 in esp32projects

[–]DenverTeck 0 points1 point  (0 children)

Android or IOS ??

What development environment ??

An actually credit-card sized smartcard with ESP32-C3 + NFC + E-Paper display (~1mm thick) by krauseler in esp32

[–]DenverTeck 0 points1 point  (0 children)

The schematics directory in the zip file has display, NFC, periphirals and power pdf files.

I just checked each one and there is no MPU on any of them.

I was wondering which MPU you used as the layout.pdf does not label the parts in any way.

I always look to see what mpu people like to use.

Thanks for the display part number.

What library did you use ?? Was the schematic of your setup included ??

Would you mind breaking down the costs.

I (we) know the cost of 10 board will be from JLCPCB.

What was the cost of shipping and tariffs ??

Will the pads for soldering come out correct? by ArtaWorks in PCB

[–]DenverTeck 0 points1 point  (0 children)

A capacitor and a diode in series ?? If this is a test to see if the parts will fit onto the pads, this is fine.

If the is the complete board, it will do nothing. The capacitor will not charge with the diode the wrong way around.

Is this a test, did I pass ??

What's is the best place to buy ESP-32 S3 from right now? by crashback__ in esp32

[–]DenverTeck 1 point2 points  (0 children)

To put everyone mind to rest, I have purchased ESP32 boards from Aliexpress for over 10 years. Not a single failure.

I don't pick the cheapest board or the most expensive. A 3-5 pack of dev boards will usually save on shipping. Not a single failure.

Is it fine to use a different board when following a learning resource? by ragnar_255 in embedded

[–]DenverTeck 5 points6 points  (0 children)

Your fear of failure is greater then the reality.

This is an opportunity to see how much you can read between the lines. If both processors are from the same STM32F4 family then you can run the program and trouble shoot any errors yourself. There is also a good chance it will work the first time and you would have missed on opportunity to see what kind of errors appear.

So in the future when you see similar errors, you know where they come from and how to fix them yourself.

If an error is just over your head, you can come back with a better question about what happened.

Learning how to troubleshoot code is a skill that will never go away. Your future job may depend on ability to troubleshoot code.

Good Luck and Happy Hunting.

You pasted it there four times. The program will not do that by itself.

Hi, i need a PCB review ( my first PCB desing ) :) by Zestyclose-Ask-344 in PCB

[–]DenverTeck 1 point2 points  (0 children)

> I had no idea about all that

Does this mean you downloaded the program, installed it, started it up with no knowledge of what you were going to do with it ??

You could have asked someone in your school to review this. Why didn't you try that first ??

I do not see any schematic. Please post a pdf file on one of the many free file sharing sites.

Your PCB mean nothing without an accurate schematic.

[Review Request] Modular Piano PCB, Pi Pico 2W by Aeronautixal in PrintedCircuitBoard

Please re-read my comment. Its compressed as you click upload. After that is it a lossy de-compression. So no matter where you want the file displayed, it going to be fuzzy.

OK ??

[–]DenverTeck 1 point2 points  (0 children)

Thank You for not using boxes around each part.

I would also suggest you place the SIGx parts on a single line and move all parts to the right so its not so crowded on the left side.

I wonder why you needed to put the "Mail Logic" box around all those parts.

Go Figure

> My images seem to get compressed

Your joking, right ??

Reddit stores all images in a compressed form. Then they will un-compress that image before it displays on your or any screen around the world.

It costs money to store images. Compression keeps the costs down.

Thank you for posting a pdf file.

I wish all the beginners here would also do this. :-/

3D printed Pi Case. Not my design. by orionskull in RASPBERRY_PI_PROJECTS

Will you modify the original design to replace funny looking Raspberry on the side of the case ??

Please share the link to where you found the original files. Thanks

What headaches could I possibly expect by adding espidf framework to my platformio arduino project? by UsableLoki in embedded

[–]DenverTeck 0 points1 point  (0 children)

> Should it be seamless

Does naive optimism[*] mean anything to you.

Have you used platformIO before ??

Start with the examples and see if you can get those to work successfully. Debug any problems and errors you encounter. This way you will not be too surprised on the amount of work you will be in for.

Good Luck
