Notes

The library shown above is simple in usage, however it does not allow for all features of the original library, which you can find here:

Import libraryDS1820

Dallas / Maxim DS1820 1-Wire library. For communication with multiple DS1820 on a single 1-Wire bus. Also supports DS18S20 and DS18B20. This fork fixes a timing problem I had with latest mbed library; allows immediate return from convert_temperature(); tidies up a few other things, including some documentation errors.
