After looking at the sht15 datasheet I know that it uses spi to communicate with the atmega. I'm having trouble interfacing this device because there is no chip select, and I have more than one sensor on the spi pins. Does the sht15 have set addr? 0? If so, what other means could I use to establish communication?
It's some code they pulled out of ...thin air.

I've not tried it.
Might need to rehydrate it.

There is no need to use the spi bus you could just bit bang the communications on any line. You won't be reading it very often (the sensor has a slow response time so there is no point) so it is no great overhead.
Thanks guys makes perfect since now.
