Hi,
Is there any technical reason why I2S is missing from the ESP32-C3 build? Is there a likelihood it will be included in the future?
Many thanks

Summary

Changed the pin numbers used for the I2S rate testing as the pin numbers used were incompatible with the limited GPIO pins availalbe on the ESP32-C3 , causing the tests to fail

Testing

Ran the updated test against:

ESP32_GENERIC
ESP32_GENERIC_C3
ESP32_GENERIC_S2
ESP32_GENERIC_S3

Trade-offs and Alternatives

Could use sys.implementation._machine or ._build to determine the board the tests is run on and adjust the pins based on that, rather than through exception handling.
