I2S.h: No such file or directory [fixed]

[silentlit]

System: MacOS Silicon

If anyone got the error "I2S.h: No such file or directory", just install the esp32 version 2.0.17 to fix it.

"Navigate to Tools > Board > Boards Manager..., type the keyword esp32 in the search box, select the latest version of esp32, and install it." It seems the latest version do not have this header file or the header file has changed to other name?

I ran the command: arduino-cli core install esp32:esp32@2.0.17 and got the following output:

Error during install: Platform 'esp32:esp32@2.0.17' not found: required version 2.0.17 not found for platform esp32:esp32

How do I fix this?

Any solution with this? I got same error on windows10

Follow the readme: Add ESP32 board package to your Arduino IDE: Navigate to File > Preferences, and fill "Additional Boards Manager URLs" with the URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

I think you might have not add the "ESP32 board package" yet.

esp32@2.0.17 is fine,but esp32@3.0.0 or esp32@3.0.1 doesn't work;because i2s library is changed into esp_i2s;

I solved it by following the steps, as well as installing the latest Arduino-cli @1.0.1

Here is an update for anyone who wants to migrate their project to the latest platform

• Migration from 2.x to 3.0

esp32@2.0.17 is fine,but esp32@3.0.0 or esp32@3.0.1 doesn't work;because i2s library is changed into esp_i2s;

change firmware.ino from i2s.h to esp_i2s.h, or stay on esp32@2.0.17 😄

Here's the diff to get it to compile with ESP_I2S. Need to do further testing though:
