<![CDATA[Using Cardputer without carputer library]]>Hello,

I want to port an MP3 player library to carputer, but there are conflicts between cardputer.h and my mp3 library.

So what I want to do is to user adafruit gfx library and SD library directly without using carputer library. But both (gfx and SD) are using SPI with different pins. How do you make it work ?
