Esp32中(scn)不可以用;(scn) is not available in esp32


The I2C scan function (scn) is intended to be used in the esp32 development board but cannot be used, including the ARV version and other versions. Represents returning 0 to 127。


Sorry, the (scn) function was broken in the latest version 2.7. I’ve uploaded a new version 2.7b that fixes this, and it now works with the same (scn) function on all platforms.

Thanks for the reminder, and let me know if it works OK for you now.
