I need to be able to add a second WIZ850io module to my Teensy 3.2. How do I change the code to address them separately?

I have used the OSC examples in Teensy and need to be able to read the code. I can program in C quite well but do not understand how to follow C++ ( I hate C++!). I need to be able to get into the library which my code is calling and make patches in the sketch. How do I find where the libraries source is etc?

Regards

I’m assuming that you are using the Arduino IDE with the teensy extension. As such, the library would normally be installed into Program Files (x86) -\> Arduino -\> libraries.

Check that folder and you will find the library complete with the .CPP (source) and .h files.

Here is a link with more information:
