Hello,
My question is not directly related to 3D printing, but with its hardware. I have a RUMBA board that works well, and a
SD card extension was with it. Since I have a fullgraphic LCD, I dont need it on my Rumba.
Currently I make some experiments with Arduino, and I would like to use this card reader directly on a Mega 2560. I look at several
schemas to wire it correctly , but I did not succeed to make it work. I tried some example sketch of the Arduino IDE, and different cabling (on pins 50 51 52 53, or the SPI pins and pin 53 or pin4... tried to Invert Exp2 and Exp1 pins... with or without 5v alimentation and gnd...).
Does someone here have an idea about how to use it?
