I succeed to put on work an Arduino Due, an Ethernet shield, a SD card and a MP3 Shield from Sparkfun, using the following libraries: Ethernet library from Arduino. Use extended SPI functions with pin 10 as chip select SdFat library from Bill Greiman. Use former SPI functions. Chip select is 9 SFE…
