error: too few arguments to function ‘itoa_my’

This error message means that the function `itoa_my` is being called with too few arguments. `itoa_my` requires at least two arguments: an integer to be converted to a string, and a character array to store the resulting string.

To fix this error, make sure that you are calling `itoa_my` with the correct number of arguments. For example, if you want to convert the integer `42` to a string and store it in the character array `str`, you would call `itoa_my(42, str)`.

If you are still having trouble, check the function signature and documentation for `itoa_my` to make sure you are using it correctly.
