Thanks! I’ve successfully imported the accelerations of x,y,z to Processing. But it seems a bit unstable. It seldom work, the majority times it read:
Error, disabling serialEvent() for /dev/cu.usbmodem142301
null
How might I fix it? (I’m trying to use AP-Sync library but I don’t know how to write my Arduino part to adopt the AP-Sync library
Here is the whole codes:
