Detailed Description

template<typename I2cMaster>
class modm::hmc5883< I2cMaster >

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.

bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::isTransactionRunning ( )
inheritedinlineprotected
Returns
true when transaction is busy.
modm::ResumableResult<bool> modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::ping ( )
inheritedinline
Return Values
truedevice responds to address
falseno device with address found
void modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::setAddress ( uint8_t  address)
inheritedinline

Sets a new address of the slave device.

Parameters
addressthe slave address not yet shifted left (address < 128).
bool modm::I2cDevice< I2cMaster, 10 , I2cWriteReadTransaction >::wasTransactionSuccessful ( )
inheritedinlineprotected
Returns
true when transaction did not return an error.
