This is my very first project and I'm trying to make work this shield http://www.adafruit.com/product/1411 with my netduino plus 1 for almost 3 days with not success. I followed all the instructions at the adafruit page on soldering, and so on, but netduino 1 SCL and SDA ports are missing so I need to use the analogic pins4 and 5.
I made the red led to turn on, feeding the shield with the 5v output from the netduino, added an extra 5v by the V+, so green and red leds are turned on.
I tried to plug the analogic pins 4-5 to the SDA & SCL shield pins, even feeding the line with 3v, but no way to get anyresponse from the device when I try to write or read from the device, for example when I try to read the register MODE1, allways returns 0, no matter what I do, no matter what I write, randomly sometimes writes 2bytes others writes 1byte.. I'm totally lost and confused, so any help/advice/direction will be wellcome.
