12.3 Routine Descriptions

The following routines are supplied by this unit.

• PhysicalConstants_get Request a physical constant given by a string, and returns its real value. This routine takes optional arguments for converting units from the default. If the constant name or any of the optional unit names aren't recognized, a value of 0 is returned.

• PhysicalConstants_init Initializes the Physical Constants Unit by loading all constants. This routine is called by Driver_initFlash and must be called before the first invocation of PhysicalConstants_get. In general, the user does not need to invoke this call.

• PhysicalConstants_list Lists the available physical constants in a snappy table.

• PhysicalConstants_listUnits Lists all the units available for optional conversion.

• PhysicalConstants_unitTest Lists all physical constants and units, and tests the unit conversion routines.

FLASH3 Transition: The header file PhysicalConstants.h must be included in the calling routine due to the optional arguments of PhysicalConstants_get.
