Member Enumeration Documentation

template<class I2cMaster >
enum modm::Mmc5603::Bandwidth : uint8_t
strong

The bandwidth adjusts the length of the decimation filter. It controls the duration of each measurement.

Note
X/Y/Z channel measurements are taken sequentially. Delay Time among those measurements is 1/3 of the Measurement Time defined in the table.
template<class I2cMaster >
enum modm::Mmc5603::PeriodicalSet : uint8_t
strong

These bits determine how many measurements are done before a set is executed, when the part is in continuous mode and the automatic set/reset is enabled. From 000 to 111, the sensor will do one set for every 1, 25, 75, 100, 250, 500, 1000, and 2000 samples. In order to enable this feature, both En_prd_set and Auto_SR must be set to 1, and the part should work in continuous mode. Please note that during this operation, the sensor will not be reset.

Member Function Documentation

template<class I2cMaster >
static constexpr uint8_t modm::Mmc5603< I2cMaster >::addr ( uint8_t  factory = 0)
inlinestaticconstexpr

The MEMSIC device 7-bit device address is 0110000 where the three LSB’s are pre-programmed into the MMC5603NJ by the factory.

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.
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.
