coretechr / retro-audio Goto Github PK

Hey,

I have a problem uploading Retro-Audio using ESP32 dev board v4 and ILI9341 2.8" screen. After successful upload display shows only blank white screen. I also tested it using my other small screen 1.8" with ST7735 and it only shows small chunk of interface. ( i think because it should be 2.8" and i try it on 1.8" but it prove that esp32 works). I also tested ILI9341 on TFT_eSPI demos and they display normally.

I use User_Setup.h that is attech to .ino file only change driver from ST7789_2_DRIVER to ILI9341_2_DRIVER or ILI9341_DRIVER

Hi, I am using your schematics as an inspiration to design an audio product, and I am wondering where is the GAIN management (and SD_MODE). The label in the sheet goes nowhere:

Could you give some detail about it ?

Many thanks !

Hi,
Since i don't have any simple solution to make the custom board, would you willing to produce and sell them ?
I would be your first customer.
Thanks

Hello, this is amazing <3
Can the headphone output function as a line level out? I know the IC you chose is a class D amplifier, so I'm wondering if you've tried connecting it to, say, the input of a home stereo. Is there a modification to the circuit design you can imagine that would easily provide line out?
thank you!

This is amazing and so cute.

I wanted to know if I can have the audio tape gif to use in my project or at least tell me what to search on google to get me gifs of this example?

Very cool project ;-)).

Could not find part "C1" in the BOM. It seems part of the Audio Output Stage. Is it a normal 0.1uF SMD capacitor? on Aisler.net is "!0.01uF" shown in the part list.
Would be the following OK?:
Vishay | K103K10X7RF5UL2 | Multilayer Ceramic Capacitors MLCC - Leaded K 50V 10NF +/-10% X7R AMMO E3

R12, R15 is also missing on BOM. Is R27 976k or 10k?
