void ds1631_convert_temp | ( | uns8 | addr | ) |
This routine starts the temperature conversion in the ds1631. Issue this command before actually reading the temperature.

uns16 ds1631_get_temp | ( | uns8 | addr | ) |
Returns 16bit raw temperature register from ds1631. Note that if you are in one-shot mode (the default) you must have already issued a start_convert and waited until it is complete (to check for completion you can either wait long enough, or query the config register to check).
