I tried using accelerometer on pins 20 & 21 but it seems like there is something wrong with the board (no, I did not use +5V anywhere). Somewhere it is mentioned DUE has two I2C interfaces, and there are pins SCL1 and SDA1 next to AREF pin. How I can switch to using them?

How to use second I2C?

Could someone post the code they are using to get I2C scanner to work on the Due? I have downloaded the fix suggested above but, I am not having luck.

Thanks,
Mark
