I build Arduino projects.
I need to connect 3 sensor boards GY521 with its DMP interruption pins to Arduino mega r3. As result I must get X-axle angles of each. I atached a sketch which receive, re-calculate and show angle data. This sketch works with one GY521, but I need 3 pcs. with possibility to enlarge q-ty GY521 to 7pcs
