Thank you for reply,
Yes, tested using IDE, but also compiled and flashed using the spark CLI. (can you point me on other way?, I know about some Eclipse plugin, …)
I will test it for some week in a device i’m building, then i will publish it. The device works using a Xively library i’ve build https://github.com/davidegironi/spark-xivelylib. Both will be published after some test.
p.s. Your DHT22 library helps me to understaind how to develop a library for the Spark world.
