    Hello, I’m working with and SD for read/write on a maple mini clone and using standard Arduino SD class. I’ve found that using this library with an ancient 32Mb (yes, Mb, not Gb) I have to add any debug (Serial.println) or delay(1) between each File.read() bec…

  15. STM32F4 Discovery

    ChrisMicro

    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…
