Hi all.

I purchased two of these

but am having issues getting them working.

it appears that the PWM output is not working for reasons unknown even though it should be enabled by default.

Any ideas? I lack an I2C to PC interface to output test strings but do have a Logic :)

regards, -A

Page 34 of the datasheet notes that you need to tie the SCL pin to Vdd for pwm operation, did you catch that?
