Cool hopefully you will see one of my netduino projects flying around the Reading area soon!
So I tried the i2C again and still nothing.
With absolutely nothing attached to the netduino the write seems to work sending 2 bytes for the init and 1 for the pre-read. The read returns 0. This is exactly the same result when I plug in the sensor with or without resistors between them and the board.
I did notice the arduino library code for the sensor was slightly different to the Netduino conversion but even changing those had no effect and would explain why the sensor seems to have no impact on the results whatsoever.
Pretty frustrating. Is there any way to test the i2c using something simpler?
Thanks again in advance for any help. I'm sure it's probably something silly.
