Where can I set the port pins to use?
RudyFiero opened this issue · 2 comments
I can't see where I can set the pin number for SDA and SCL.
I found where to set the pins used. So I tried to compile the example sketch and I got the following error.

I added the library
SoftI2CMaster https://github.com/felias-fogg/SoftI2CMaster
And then tried to compile your example. I now get the following errors.
