Thanks all!

Pin 16 of PCM5102A is tied to GND: Audio format selection : I2S (Low) / Left-justified (High)
I am powering the PCM5102A DAC from a regulator on the board, not from ESP32 3.3V.
Supply looks stable.

Increasing f.read(2048) gives a timeout error. f.read(1024) does not help.
I ...

hello!
I have an ESP32-S3-WROOM on a custom PCB.
I'm retrieving a wav file (a song) from an SD card via SPI and playing it through DAC PCM5102A using I2S.

I am able to retrieve any wav file from the SD card and write the name of the file to the shell.
I am also able to play a generated tone with ...

Thanks, the issue was using GPIO10 as an output. Appreciate the response!

Hi-
I uploaded the same code as I'd been using to two ESP-WROOM-32E modules (Arduino version 2.3.3)
(at the bottom of this post)

I can still get the code to upload on each module, and can erase the flash with pytool. I have switches on GPIO and EN.
esptool.py --chip esp32 --port /dev/tty ...

Turning over the cable worked!
Thanks @sprite and also for the USB spec info.

Hello!
I designed a board with a ESP32-C3-MINI-1-H4 and a USB to UART connection to use Arduino.
My board isn't recognized by USB and I wondered where things might be wrong.

I have switches to EN (pin 8) and to GPIO9
GPIO8 measures HIGH
GPIO2 measures ...

Many thanks!

I'm planing on using the Arduino framework, looks like you can change pin numbers for I2C and SPI there too.

Hello! I'm wondering why on the peripheral diagram for the C3 MINI the D+ and D- pins show 0R resistors.
Is this because they can be configured as GPIO pins?
If I want to use these pins for USB do I need to add resistors and if so, what value?
Thanks!

Hello!
I wondered if there are specific pins to use for I2C and SPI for the ESP32-C3-MINI?
I haven't been able to find this in a datasheet/ anywhere else.

Is there room for both I2C and SPI ? Thanks in advance!
