Detailed Description

HMC5843 digital compass driver.

This class extends the Hmc58x3 family driver only by the addition of device specific Register bit masks.

For further information on this device consult the datasheet.

Member Function Documentation

void modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::attachConfigurationHandler ( I2c::ConfigurationHandler handler )

inheritedinline

Attaches a configuration handler, which is called before a transaction, whenever the configuration has to be changed.
