Title: Errors compiling projects which depend on SD.h or SPI.h
Post by: diginerd on October 13, 2015, 09:12:19 am

I'm having issues with the bundled SPI library when compiling even a basic application just based on the following includes:

Code: [Select]

#include <SPI.h>
#include <SD.h>

I get the following errors:

Code: [Select]

Error compiling.
Does anyone know how to resolve this?

If others encounter the same issues, they may be resolved by copying the SD library from the Arduino 1.5 github branch. Newer and older versions of the SD card library are not compatible with the SPI library which comes with the DigiX.

Are there any plans to update the SPI library?
