__gpiomux, __gpiofunc size about esp-i2c

[juhovh]

You are correct that all the values are of type uint32, but when they are assigned to the uint8 array they are truncated to the one least significant byte, which is the GPIO mux index. Then PERIPHS_IO_MUX_GPIO macro adds the PERIPHS_IO_MUX address back to it and returns it to the original value, meaning the code should work just fine.

I guess I could change it for clarity, but then again the "if it ain't broken, don't fix it" principle would suggest we can keep it as it is, unless you are having any issues with the code?

The compiler gives me error and could not go further even it works with uint8.
(with treat warning as error.)

I guess that's a good enough reason, I just pushed commit ab77ad5 please check and confirm that it fixes the problem.

[alsaleem00]

yes. it solved the issue. I tried already.

Thanks.
