evc_pt2257's Issues

Can I use a LCD screen with the PT2257?

Hello,

I'm using a LCD screen on pins A4 and A5.
Is it possible to get conflicts when pins for the pt2257 are set on A0 and A1?

Because if I only use Pt2257, there's no problem but if I add a LCD screen with i2c bus, the LCD is going well but PT2257 seems to be off...

Is there a solution to use the 2 at the same time?

thanks a lot

Gilles

Compiling Issue would be glad if you can Help me.

Hello,
I´m relativly new in the World of Arduino. But i want to build a Speaker wit the PT2257 and your libary. And I have a Problem with it. I use Win10Pro and Arduino 1.6.11. I Downloaded your libary installed it and tried to run the Example Code, but I always get a Error that there is something wrong with compiling (exit status 1) I tried to delete the Libary and install it again but it didn´t helped either. It would be glad if you can help me. Thanks
Greetings
Niklas

Here is my full Error Code:

Fehler beim Kompilieren für das Board Arduino/Genuino Uno.

Issue compiling with arduino nano.

It might be an issue with the Softi2c library since I've never used it before, but when I tested that on it's own it seemed fine. If there is another version that uses the built in i2c interface that would work fine, or if I could get help with this issue that would be nice.

Here is the error if you want it.

Doesn't compile for arduino uno

Hey, thanks for creating this library.
I'm trying to compile the example sketch for my arduino uno, but I constantly only get error messages:
