Unable to select suitable driver for this board

More details here: http://forum.dexterindustries.com/t/grove-dht-and-golang-in-general/3187 i2cdetect returns the expected result, but I still get the error.

Hi. It's probably the library. When starting up, the library needs to select an appropriate driver for the board. Different boards support different hardware. There is a raspberry pi driver, but it looks in /proc/cpuinfo for the presence of BCM2708 or BCM2709. Chances are you've got a newer raspberry pi that uses a different chip set. Can you post the contents of /proc/cpuinfo from your raspberry pi? And what model of raspberry pi do you have?

I've added

if strings.Contains(s, "BCM2708") || strings.Contains(s, "BCM2709") || strings.Contains(s, "BCM2835")

And it seems to work, I'll test it a bit more to be sure and will provide updates.

Ok sweet. I don't have a board to test it on. The Raspberry Pi driver firstly detects if it applies (the test you've amended), but it also contains a function createPinData() that selects configuration for boards, since the raspberry pis sometimes change their hardware with each revision. The default case in that function is for a rasppi B+. From what I can see online, the 3 model has the same pinouts as the B+, so the B+ config should work. Just be aware that there can be differences.

Do you want to create a pull request for that change, or would you like me to apply that?

Ok, awesome, thanks. Yep, I can make a PR tonight when I'm back home.
