MCU With More Than One I2C

[mohdrais]

Hello, I am using Pico W and I want to run DS3231 by using I2C1 (Wire1). How to do that? (It works when using I2C0 (Wire).

I'll try to define it as constant and try to be able to define it before the include. But last time I tried it didn't work (it was like 2+ years ago)

I've seen it's already done for Attiny. You can test it definining URTCLIB_WIRE before including the library:

    #define URTCLIB_WIRE Wire1
    #include "uRTCLib.h"

Sorry, it does not work for Pico W. Thank you

Then the quick way is to copy library on Sketch's folder (under libraries folder) and change definition line:

https://github.com/Naguissa/uRTCLib/blob/master/src/uRTCLib.h#L48

Change it from Wire to Wire1

So, this way folders will be like:

[...]/Arduino/YourSketch/libraries/uRTCLib
[...]/Arduino/YourSketch/libraries/uRTCLib/src
[...]/Arduino/YourSketch/libraries/uRTCLib/src/uRTCLib.h ==> This is the modified file
[...]/Arduino/YourSketch/libraries/uRTCLib/src/uRTCLib.cpp
