Ambiguous "begin" overload

[andreburto]

When following the CoreInk Quick Start tutorial I got the following error:

/Users/andrew/Documents/Arduino/libraries/M5-CoreInk/src/M5CoreInk.cpp: In member function 'int M5CoreInk::begin(bool, bool, bool)':
/Users/andrew/Documents/Arduino/libraries/M5-CoreInk/src/M5CoreInk.cpp:23:33: error: call of overloaded 'begin(int, int, int)' is ambiguous
         Wire.begin(32, 33, 10000);

Error compiling for board M5Stack-CoreInk.

My fix was to change line 23 in M5CoreInk.cpp from...

Wire.begin(32, 33, 10000);

to...

Wire.begin(32, 33, (uint32_t) 10000);

That eliminated the ambiguity and the code compiled as expected. Is this a common issue or something unique to my setup? Is it worth my making a branch? I am using the following setup:

OS: macOS Catalina Arduino: 1.8.19 M5Stack CoreInk: 0.0.2 ESP32 libraries: 2.0.1

Hello @andreburto

thank you for your proposed fix. I've seen the issue in other projects and I think it is related to the 2.0.x version of the ESP32 libraries.

Thanks Felix
