Hi, the documentation says that this pin is pulled up to 3v3 via 10K resistor, if I want to use this DAC output does that mean I have to remove the shield and remove R11 first?

Hi, I'm getting following error message when trying to use the ota update functionality (or basically when starting the server for the firmware): python simple_ota_example/example_test.py ['ESP32'] Traceback (most recent call last): File "simple_ota_example/example_test.py", line 118, in <module> de...

The processing itself is not the problem, how to acquire audio via ADC/DMA(DIG) is the question.

ok got everything sorted out. some formula is a bit difficult to understand and not well documented it seems.

Hi,

does anyone have an example how to sample audio with the esp32-s2 via ADC?
As far as I've seen the i2s api doesn't work or isn't fully implemented to work via DIG on the esp32-s2 with the current esp-idf package.

I want to sample 44100hz/1 channel/8bit (so 12bit is ok).

Thanks for the answer!

Hi,

is it possible to use the ESP32-S2 als a USB Gadget with custom descriptors and isochronous/bulk support?
Does it support 12mbit (or more) via USB 1.1 (or higher)?

Hi, I'm trying to flash the blink example but it doesn't seem to go well. I'm using a raspberry PI for the JTAG connection. My board is an ESP32-WROOM-S2 breakout board. openocd -f interface/raspberrypi-native.cfg -f board/esp32s2-kaluga-1.cfg Open On-Chip Debugger v0.10.0-esp32-20201202 (2020-12-10...

I just figured that out 10 minutes ago .. yes it needs idf.py build it fixed the problem

thanks for your quick reply!

Hi, I tried to follow the steps for setting up the esp32-s2 toolchain for the esp32-s2-wroom module however it doesn't really work. I'm following those steps: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/#get-started-configure $ cd /Users/markus/devel/esp32/esp-idf/example...
