Hello! I must have messed up somewhere... I am trying to connect the MU camera to BiBoard, using SCL & SDA pins from p16 and 5V & GND from pins p17. I set the right-side toggles on MU to address 0x60, and set MU_ADDRESS in camera.h to the same value. When I start Bittle, the initialization sequence gets stuck at "Scanning I2C network..." (if the camera is not plugged in, then the sequence just goes through as normal) Any suggestion? Thanks!

On a new Nybble (1_1 board) that has been working great so far, I made some small changes to the code, and somehow got it to crash in a loop - it resets ever second or so with a loud beep... And as a result, I am not able to upload new code... I tried various combinations of unplugging / plugging the USB cable / pressing the reset button / uploading. Nothing seems to fix it... Any suggestion? Error from Arduino tool on Mac: Sketch uses 592 bytes (1%) of program storage space. Maximum is 32256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes. avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x0a avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x2a avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x20 avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x53 avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x74 avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x61 avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x72 avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x74 avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x20 avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x2a An error occurred while uploading the sketch And this is what the serial monitor shows below.
