i modified it a bit to make it work, but it shows exception at start about the soft reset
anyone knows what is wrong? i power it at 3v (tried 5v too) and the DATA and SCK on IO19, IO18.
P.S. General question: its annoying that wires are not fixed on their position(board, sensor etc) and when i try to wire something , something else goes out. How do you make the wiring guys? Cause im new to these stuff.
what do you mean? its the breakout board from sparkfun http://www.sparkfun.com/products/8257
so the clock pin has a 10K pull-down resistor, and data pin has a 10K pull-up

The values you’re getting are Max’ed out negative… This happens when its reading 0xFF ( all bits high ) which means there is no communication…
I’ve noticed that on the breakout board they have the SCK line with a pulldown resistor!! You need to check if you have a clock signal… I don’t know whether the device driver on the FEZ is driving the pin high the serial transfers.
This driver is for a different device… Are the registers the same?
yea sorry i forgot to write it. ^^
Thanks for your replies, your post helped me when you said max values mean no communication.
So i played with the volt and pins and finally pins should be opposite from what the driver(from fezzer) says.
it said on the comments first clock pin then data pin and 3.3v
but eventually its first data pin and then clock pin and 5v for SHT15.
I wanted a light detector sensor, i bought it in order to check the light on the room so i can check if its night or day. But finally i don’t know if i bought the correct one.
(i bought this because the EU distributor of GHI (antratek.com) didnt have the GHI Light Sensor unfortunatelly)
