DIY micro tower (desktop version)

heyk after downloading the spectrum file, opening it in an arduino program and releasing it for verification, it gives errors

I also got an error. It turned out that the TFT_eSPI library is too new for core 1.0.4. After installing version 2.4.79 the verification went positive. Whether it works I don't know because I only verified(waiting for parts) 🙂 Maybe it's the same for you.

The compilation conditions are given at the beginning of the source file:)
If there are Tft_espi problems with the core version of ESP32 1.0.4
I suggest changing the entry in the library directory:
... Processors/Tft_espi.h
Comment out the entry #hal/gpio_11.h

>>21907037 a tell me through which ardu you upload which version ba I version 2.3.6

>>21907042
What error does it throw?

>>21907042 I have the latest 2.3.8 . efi222 I have seen🙂 but it was giving errors. I was prompted by gpt chat, as I say I haven't checked if it works because I don't currently have anything to use it on, but verification passes. Now for a test I updated to the latest and here is the error:

And have you downgraded the ESP32 core version to version 1.0.4?
You have core version 3.3.8

efi222 sorry I didn't notice this post. I have another question because I had to comment out one eeprom library (#include "eeprom.h) because I was also getting errors popping up. Does it have the right to work this way? I'm sitting on linux and the chat mentioned wrote to comment this one out because linux is case sensitive in code and hence the errors.

How's it going gentlemen, can anyone help how to bite it.

Added after 1 [minute]:

No, I haven't changed, but I'm already reinstalling.

@wieh76
I'll try compiling without this "eeprom.h" today and let you know the results.

There is one more issue.
There is a directory SETUP_TFT_ESPI in the spectrum source directory. Inside it is the file "User_Setup". This is the settings for the display driver and the SPI bus. This file needs to be copied to the root directory of the TFT_espi library and swapped with the original. Just archive the original somewhere before swapping.
I think I'll do some additional description in the article.
TFT_espi is not one of the very friendly ones.... (But for that, it drives "like a little car" ).

>>21907075 I don't know maybe it's linux😀's fault. There are two of these libraries there which is why I ask. As for the description, it would be useful because I didn't know about the swap or didn't read about it. And the analyzer "nice" great thanks for the work and the project.

Changing the core helped and it even uploaded to the esp only nothing is displayed because the author uploaded directly to the esp and I uploaded to the development board, I connected the pins as in the diagram but nothing is on the display.

If you don't mind: at my place the combo went. Esp32D in 30 pin module, memory settings standard, Arduino version as recommended, Esp32 Espressif 2.0.17 board definitions and in addition in preferences
h t t p s ://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json.
"From the package" there is still an encoder mismatch: in variables.h gpio 25 and 26, in the schematic 25 and 27. The board a little improved compared to my first version - this encoder + stabilizer, you can assemble or not.

A revelation, thanks and greetings to the Author.

Have you done this?

With such a Core the bandwidth processed is 10kHz max

There should be a version 1.0.4

I'm already doing it, I had a little problem with the electricity at home.

And I am to understand that the connection of the ESP vs the displays is to be connected according to the file I am swapping.

Added after 2 [minutes]:
It has started up and is working, I still need to connect the encoder.

Or with the diagram. Only there is an encoder connection error on the schematic. It should be on IO25 and IO26

and tell me, because I have an encoder with the designation s1 s2 key and power supply, how in this situation s1 under 25 s2 under26 key under gnd

ok the encoder has gone in without connecting the key

Thank you very much for the hints I am still taking on the preamplifiers and I will enjoy your awesome project and I will still ask you for the print file as of course you can total all 3 print files but this I will write right away on private

Something's up - a 1 kHz sine from the generator gave a bar between 6 and 8 kHz On core 1.0.4, with TFT_eSPI in the recommended version, changing the user_setup in the library folder and it threw an error:



No such file or directory
compilation terminated.

I'll play around some more.

A mental abbreviation - obviously did not mean "prototype" (first copy by colleague efi222). Sorry, and already corrected

This has solved the problem. Thank you very much for your help.

I have updated the title post. I have included some tips at the bottom to make it easier to run the spectrum.

@efi222 And have you corrected this error with the polarity of the right speaker?
If you leave it as the Chinaman described, then you have the right channel connected in counter-phase. And given that at low frequencies, there are always negligible phase shifts between the channels, they cancel each other out with such a connection, resulting in a heavily muted listening experience.
If you connect it correctly, as I wrote, you will hear what the difference is.

I've checked the compilation without this eeprom.h. It compiles correctly and the spectrum works.

I plugged the speaker in reverse temporarily. I must say that the stereo space and overall sound has improved. Thanks again

efi222 wrote:

It must have improved because, after all, by having one speaker in counter-phase, the audible space was severely distorted. As is well known, phase differences play a big part in this aspect.

Another previously undescribed feature regarding spectrum:
Wireless software update (*.bin).
After holding down the "update" button for about 3 seconds, the display will show that the ESP has "entered" AP mode.
You need to log in to the specified Wi-Fi access point " micro_widmo " - password: 12345678
After logging in (ignore the message about no internet if it appears), you need to enter the IP 192.168.30.50 in your web browser
The web page should launch.
If AP mode has been running for a long time, I recommend refreshing the page before updating.
This option is a little test version (working).
