I am trying to replicate the solution given in topic Add DATE and TIME to your SD CARD Files.. However, the line SdFile::dateTimeCallback(dateTime); throws error: no matching function for call to 'dateTimeCallback(void (&)(byte*, byte*)). I'm using the libraries (SD.h and SPI.h) that are included in the carrier of the Explore IoT Kit. Is there an issue with them or I'm not doing this right?? Thanks in advance.
