PWM shield use on Due
I would like to use the PWM shield on a Due board. I see from the product page that Due is listed as compatible but there is no output on the shield. The shield works when I use it on a Mega2650 with the same sketch. I used the 3.3V VCC jumper and confirmed all the voltages were at 3.3V including the I2C pins on A4/A5 and the alternate pins above Aref. There is 0 volts on the PWM output pins regardless of the command given, which works fine on the Mega2650. Any help would be appreciated.

Pretty much any board, but the DUE will work. The DUE has a i2c implementation that does not play well.

you may need to address it as Wire1 - but really, we do not recommend the Due, it has a lot of I2C problems.

Thanks I got it working great with Wire1.
