Metro M0 Express + Music Maker Shield Problems

by Dread-Eye on Fri Feb 09, 2018 7:23 pm

My Music Maker Shield works fine on an Arduino Uno, but I get nothing when mounted on a Metro M0 Express (which also works fine). I've added:

Code: Select all | TOGGLE FULL SIZE
#if defined(ARDUINO_SAMD_ZERO) && defined(SERIAL_PORT_USBVIRTUAL)
  // Required for Serial on Zero based boards
  #define Serial SERIAL_PORT_USBVIRTUAL
#endif

to the Simple Player sketch which uploads without any issues. But, nothing plays and nothing appears on the serial monitor. Any advice?

The M0 Express doesn't use pins 10-13 for the SPI interface. Those signals are on the 2x3 header at the end of the PCB.

You'll need to modify the solder jumpers on the back of the shield to make it work with the M0:
