i have a simple PIR/wave shield project i am failing to port from my Diecimila 328 to my lipo battery powered Pro Mini 328. I prove different sketches on the Diecimila and then move the shield to the mini, load the sketch and only get errors on sketches that use the SD card.
Code: Select all
WaveHC with 6 buttons
Free RAM: 608
Card init. failed!
SD I/O error: 1, FF

does the waveshield v1.0 use the AREF pin?
it is the only pin not broken out from the shield to the Pro Mini.
