SD only partially works.

Today I found some time to test the default arduino SD library (SD) with my STM32F103CT8. At the first, It didn’t worked (at least to me). But after a few additional lines to the standard library it worked. Edit the file Sd2PinMap.h (arduino-1.6.4\libraries\SD…

Using Roger’s repository, you can simply copy the Wire library from STM32F1 into STM32F4, or even create a symbolic link. Thank you very much. That’s a good hint. I wonder why Roger is not copying the library itself in the repository. My goal is to use the cod…
