Arduino for STM32

I have no idea what ''stm32_i2s' is not a namespace-name' does mean, since is defined at the begining of the 'stm32-i2s.cpp'.

PS: OK, now the code compiles, if I make this code work I will mark it as 'solved'.
Does error disappaer after restarting ArduinoIDE?


Not sure, maybe the problem ...

I never made something with I2s on STM32.
Do you know this: https://github.com/pschatzmann/stm32-i2s ?
Do you connect SD-card on ESP32 as SPI or SD-MMC?


Sorry I wasn't clear enough. I'm trying to make work just the I2S, without the SD card connected to other SPI peripheral, for testing purposes ...

Hello,

I’m developing an autonomous audio recorder that captures signals from a custom amplifier, uses the PMOD I2S2 ADC, and saves them to an SD card at 16-bit, 44.1 kHz (this requires MCLK).

It’s working on an ESP32, but I want to compare different MCUs, primarily to optimize power consumption ...

Hello! I'm Miguel from Argentina.

I'm currently developing a project on ESP32 on the Arduino IDE and I would like to test it on the STM32.
Before transitioning to STM32CubeIDE, I would like to try if it's possible to make it work on the Arduino IDE.
Because of this, I might need your assistance
