Hello,

I am trying to stream full duplex audio between an ESP32S3 (Adafruit Metro board) and a remote computer, for now a Raspberry PI.
I can send UDP audio packets from the Raspberry PI to the ESP32 over WiFi. I send a packet every 10 ms, capture it on the ESP32 and push it to the I2S bus to be ...

If I define:

target_compile_options(${COMPONENT_TARGET} PUBLIC
-DARDUINO=10812
-DARDUINO_${idf_target_for_macro}_DEV
-DARDUINO_ARCH_ESP32
-DARDUINO_BOARD="${idf_target_caps}_DEV"
-DARDUINO_VARIANT="${CONFIG_ARDUINO_VARIANT}"
-DARDUINO_USB_CDC_ON_BOOT=1
-DARDUINO_USB_MODE=0
-DESP32)

Then I ...

Ok that's easy to do. Do I define the macro before the call to initArduino, or should the #define be used to compile the whole component? When looking at HardwareSerial.h it looks like the define are needed when compiling the components.

Thanks


#if !defined(NO_GLOBAL_INSTANCES) && !defined(NO ...

Thanks, I see that but I am trying to build my app with the IDF tools (Arduino is installed as a component) but I cannot find the right setting. I get the expected result if I use the Arduino IDE, I get the expected results.

Thanks

I am using Arduino as an IDF component and I am able to run code on the Metro board. I can see the ESP_LOGx messages in the "idf.py monitor" window, but I am not seeing the Serial.print() output? Where is Serial configured. I would like the Serial.print to go to the USB out, same as ESP_LOG.

Thanks

I am trying to implement the Thread Border Router (https://docs.espressif.com/projects/esp-thread-br/en/latest/dev-guide/build_and_run.html)

When I run my code, this is the output I get from my esp32s3 chip:

I (4978) RCP_UPDATE: RCP: using update sequence 0

Hello,
I am trying to run the code (esp-idf/examples/openthread
/ot_br/) on an ESP32S3 (Wroom) board. I believe configure everything right based on the Readme file.

This is the output I get when I do 'idf.py monitor'

ESP-ROM:esp32s3-20210327
Build:Mar 27 2021

v5.0.2

On my ESP32S3, I am registered a callback function to get my audio data.

I use 32 bit stereo at 48 kHz, with 10 ms blocks. The size member of the i2s_event_data_t structure is always 3840 which is 480*2*4. This is good.

I do not understand the data pointer. When I dump what is pointed to by data ...

You are right! My mistake. I fixed my wiring and everything looks good on the logic analyzer.
Sorry about that.
